Surface Properties of Whey Protein Gels

Surface properties of whey protein gels are reviewed based on traditional microscopic techniques and new methods, as optical profilometer and contact angle measurements. Optical profilometer is an instrument allowing measurement of surface roughness and contact angle measurements to determine the surface wettability behavior (hydrophobicity/hydrophilicity) of the gels. Investigation of surface properties of whey protein gels is very important, as it can transform this product to a new level of application. It could be used as a matrix for an active ingredient release, material for tissue engineering, e.g. scaffolds, i.e. temporally structures biodegraded in the human organism.

Condensate blockage alleviation around gas-condensate producing wells using wettability alteration

In the current survey, a novel fluorocarbon-based wettability modifier chemical is proposed to alter the wettability of sandstone rock surface from liquid wetting to preferentially gas wetting condition. Several experimental tests describing wettability condition of the rock surface including static contact angle measurements, spontaneous imbibition and dynamic core flooding using water and n-decane fluids were conducted on untreated and treated sandstone rock to investigate the effect of the proposed chemical on surface wetting behavior. Adsorption of fluorinated chemical on sandstone surfaces was characterized using FTIR and SEM. Elemental analysis of rock surface after treatment was determined by EDX analysis and EDX map. After chemical treatment of sandstone thin section, contact angles of water and n-decane in air-liquid-rock system were altered from 0° and 0° to 151° and 101°, respectively. Spontaneous imbibition of water and n-decane as imbibing liquid fluids into the core sample saturated with dry air at room temperature on untreated and treated core showed that the ultimate amounts of liquid imbibitions were decreased to factors of 0.03 and 0.16 PV, demonstrating wettability alteration from strongly condensate-and water-wet to preferentially gas-wet condition, respectively. Also, the results of core flooding experiments demonstrated the improvement of liquid phase mobility as a result of treatment with proposed chemical fluid by factors of 3.85 and 3.5 for water and n-decane, respectively. The outcome of this integrated study proposes that fluorochemical agents can be considered as a promising candidate for possible field applications to alleviate both condensate and water blockage in gas condensate reservoirs by wettability alteration technique.

Cellulose/polyacrylonitrile electrospun composite fiber for effective separation of the surfactant-free oil-in-water mixture under a versatile condition

Abstract In this study, a simple electrospinning method was employed for the fabrication of a durable and renewable cellulose/polyacrylonitrile (cellulose/PAN) composite nanofiber by alternatively piled one over other as stacking. The stacking layers of cellulose/PAN composite fiber was subjected to the hot roller press at 80 °C to enhance the firm attachment of fibers. The hydrophilic composite fiber was fabricated for oil-in-water mixture separation in harsh conditions of different pH. The fibers were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and thermal stability was monitored by TGA analysis. The tensile stress and the surface wetting behavior were greatly improved for cellulose/PAN composite fiber. The different oils like n-hexane, diesel oil, and toluene were used to prepare oil-in-water mixture solutions. The hydrophilic composite fiber served as a substrate to ensure the high water permeation flux and high separation efficiency with excellent stability and durability. This work projects an easy cost-effective fabrication method of composite fiber for on-demand oil-in-water separation process having good application in adverse situations with excellent recyclability and the maximum separation efficiency up to 97.31%.

Surface wettability of montmorillonite (0 0 1) surface as affected by surface charge and exchangeable cations: A molecular dynamic study

Surface wettability of swelling clay minerals plays an important role in the flocculation-dispersion, sorption, flotation and interfacial interactions behaviors. But it is difficult to determine, not only for the small particle size, but also for the abilities of hydration and swelling. In this work, surface wettability of montmorillonite (0 0 1) surfaces as affected by surface charge and exchangeable cations has been investigated through molecular dynamic (MD) simulations. The adsorption energy between montmorillonite (0 0 1) surface and water molecules was calculated to qualitatively characterize the wettability behaviors, and more negative adsorption energy means stronger affinity between montmorillonite surface and water molecules. It has been found that the negative charged montmorillonite surface has very weak adsorption energy for water molecules but very strong electrostatic attraction for exchangeable cations. Besides, these exchangeable cations have very strong hydration ability thus to acquire several layers of hydration shells around the cations, the effect of which is to impart an overall hydrophilic nature to the clay mineral. As a result, exchangeable cations are being adsorbed on montmorillonite (0 0 1) surface in the form of ionic hydration shell. And it is the exchangeable cations that have much stronger affinity to water molecules than montmorillonite surface, thus the adsorbed exchangeable cations on montmorillonite surface play the dominant role in determining the surface wettability behaviors.

Rapid, Template‐Less Patterning of Polymeric Interfaces for Controlled Wettability via in Situ Heterogeneous Photopolymerizations

AbstractTuning macroscopic behavior between a synthetic surface and the surrounding environment requires precise engineering of micro‐ and nanoscale features at the interface. As one example, the geometry and spacing of topographical structures can be manipulated to modify interfacial interactions with water. If optimized correctly, topographical features can impart macroscopic wetting behavior that goes well beyond what is expected from the chemistry of the surface materials, such as strong hydrophobicity from intrinsically hydrophilic materials. However, developed techniques such as templating or nano‐lithography require significant processing times and are often ill‐suited for in situ applications. This work shows that polymeric interfaces with regular, ordered topographical features can be generated using a rapid in situ photopolymerization technique that requires no templating nor additional processing to generate or manipulate surface features. Maximizing the local differential in polymerization‐induced shrinkage between heterogeneous domains results in the formation of robust 3D surface features. Furthermore, the spacing and density of these features can be optimized through the phase separation process, yielding surfaces with variable wetting (θw ≈ 90–130°). These results demonstrate that template‐ and mask‐less surface patterning is possible with rapid polymerization techniques and that it can be easily manipulated to vary surface wetting behavior.

Surface wetting behavior of nanocellulose-based composite films

Thin nanocellulose-based composite films (approximately 25 μm) were made with cellulose nanocrystals (CNCs), cellulose nanofibers (CNFs), and Zn(2-methylimidazolate anion)2 (ZM) modified CNFs for potential use in energy storage devices such as battery separators. The film morphology and surface wettability were studied in comparison with a commercial Polypropylene-Polyethylene-Polypropylene (PEP) battery separator film. Five different models were used to determine the dispersive and polar components of surface free energy (SFE) for the films and wetting envelopes for various films were constructed. Varied morphology from mixed CNC and CNF composite and increased film porosity coupled with reduced O–H groups on the surface of modified CNFs led to increased surface wettability of CNC–CNF and ZM–CNF films, respectively. All cellulose-based films showed better surface wetting behavior compared with that of the PEP film. The Owens–Wendt–Rabel–Kaelble (OWRK) method was suitable for calculating SFE components of the composite films. The total SFE of the CNC–CNF and ZM–CNF films varied from 42.55 to 53.87 mJ/m2 in comparison with 20.19 mJ/m2 for the PEP film. The constructed wetting-envelopes can be used to predict the wetting behavior of different solvents on the composite films for target electrochemical applications.

Wettability of porous anodic aluminium oxide membranes with three-dimensional, layered nanostructures

The architecture-dependent wettability of three-dimensional (3D), porous anodic aluminium oxide (AAO) membranes with varying surface morphologies including hierarchical, mesh and honeycomb nanostructures is reported. The surface morphology and underlayer structure play different roles in regulating the wetting behaviour of the AAO membranes. For the mild AAO membranes, the wetting behaviour of the ultra-thin top layer is dominated by the surface morphology in which the water contact angles (WCAs) of the AAO membranes with hierarchical, mesh and honeycomb structures are approximately 113.7° ± 4.6°, 94.9° ± 0.7° and 98.8° ± 5.8°, respectively. The wetting behaviour of the 3D, layered AAO membranes is dominated by both the surface morphology and the underlayer structure. Notably, the WCA of the mild AAO membrane with a layered hierarchical structure increases in the second layer (increase in the hole density). The WCAs of the three kinds of layered hard AAO membranes decrease in the second layer (increase in the hole depth) and then decrease slowly or increase in the third transition layer (decrease in the hole density). The WCAs of all the AAO membranes decrease linearly at different rates with the formation of the ordered bottom layer. The above results can facilitate the engineering of nanostructures for controlling the surface wetting behaviour of materials and devices for applications in multiple fields.

Microfluidic Devices for Characterizing Pore-scale Event Processes in Porous Media for Oil Recovery Applications.

Microfluidic devices are versatile tools for studying transport processes at a microscopic scale. A demand exists for microfluidic devices that are resistant to low molecular-weight oil components, unlike traditional polydimethylsiloxane (PDMS) devices. Here, we demonstrate a facile method for making a device with this property, and we use the product of this protocol for examining the pore-scale mechanisms by which foam recovers crude oil. A pattern is first designed using computer-aided design (CAD) software and printed on a transparency with a high-resolution printer. This pattern is then transferred to a photoresist via a lithography procedure. PDMS is cast on the pattern, cured in an oven, and removed to obtain a mold. A thiol-ene crosslinking polymer, commonly used as an optical adhesive (OA), is then poured onto the mold and cured under UV light. The PDMS mold is peeled away from the optical adhesive cast. A glass substrate is then prepared, and the two halves of the device are bonded together. Optical adhesive-based devices are more robust than traditional PDMS microfluidic devices. The epoxy structure is resistant to swelling by many organic solvents, which opens new possibilities for experiments involving light organic liquids. Additionally, the surface wettability behavior of these devices is more stable than that of PDMS. The construction of optical adhesive microfluidic devices is simple, yet requires incrementally more effort than the making of PDMS-based devices. Also, though optical adhesive devices are stable in organic liquids, they may exhibit reduced bond-strength after a long time. Optical adhesive microfluidic devices can be made in geometries that act as 2-D micromodels for porous media. These devices are applied in the study of oil displacement to improve our understanding of the pore-scale mechanisms involved in enhanced oil recovery and aquifer remediation.

Effect of microstructure and surface features on wetting angle of a Fe-3.2 wt%C.E. cast iron with water

In the present study, variation in surface wetting behavior of a hypoeutectic cast iron with its microstructural features and surface roughness was investigated. Samples with an identical composition, i.e. Fe-3.2 wt%C.E., and different microstructures (a gray cast iron with A-type flake graphite and a white cast iron) were fabricated by gravity casting of molten cast iron in a chill mold at different cooling rates. A variation of surface roughness was also developed by polishing, a four-stage electroetching and a four-stage mechanical abrading on the samples. Roughness and water contact angles of all surfaces were then measured. The surface roughness factor and the solid fraction in contact with water by the Wenzel and Cassie-Baxter contact models were also calculated and compared with the corresponding measured contact angles to find out which regime was active. Results indicated that the surface microstructure and the type of constituents present at the surface influenced the cast iron surface wettability and that it was possible to change the surface contact angle by modification of the surface microstructure. The mechanically abraded gray cast iron followed the Wenzel-type regime while the electroetched surfaces of gray cast iron exhibited a transition from Wenzel to Cassie-Baxter type regime. In white cast iron, the results indicated Wenzel type behavior in the electroetched samples while for the mechanically abraded samples, none of these two models could predict the wetting behavior. Furthermore, the wetting angles of both gray and white cast irons were measured after 1, 2, 3 and 4 weeks of air exposure. The results showed that the wetting angles of both samples increased to above 90° after one week of air exposure which was likely due to adsorption of low surface energy hydrocarbons on the surfaces.

Innovative metallic solutions for alpine ski bases

Ski manufacturers are interested in improving ski performance in terms of rapid sliding, excellent trajectory control, and reduced maintenance. A possible approach to achieve this goal is based on substitution of the base material, moving from the standard ultra-high-molecular-weight polyethylene to metallic solutions. Despite their elevated mechanical properties, however, metallic materials exhibit a poor sliding behavior, at least in their original manufacture condition. Although the interaction between the ski base and snow is still an open field, the authors investigated the relationship between ice friction and material hydrophobicity. The wettability behavior of surfaces can be managed by surface patterning techniques, among which laser surface texturing (LST) is a promising method, permitting surface feature modification from the micrometer- to millimeter-scale, and attractive for industrial applications. Herein, the tribological properties of two metallic materials are investigated and a process to reduce the sliding friction against snow is proposed. The LST is used to realize dimple patterning on the metallic surfaces, where the laser parameters are used to control the dimple geometry and surface wettability using untreated substrates as a reference condition. Finally, characterization using a prototype snow tribometer was performed to determine the friction coefficient and sliding performance of the laser-treated metallic surfaces.

Critical heat flux for flow boiling of water on micro-structured Zircaloy tube surfaces

We investigated the influence of surface structure on critical heat flux (CHF) for flow boiling of water. The objectives were to find suitable surface modification processes for Zircaloy-4 tubes and to test their critical heat flux performance in comparison to the smooth surface tube. Surface structures with micro-channels, porous layer, oxidized layer, and elevations in micro- and nanoscale were produced on Zircaloy-4 cladding tube. These modified tubes were tested in an internally heated vertical annulus with a heated length of 326 mm and an inner and outer diameter of 9.5 and 18 mm. The flow boiling experiments with water were performed with mass fluxes of 250 and 400 kg/(m2 s), outlet pressures between 120 and 300 kPa, and an inlet subcooling temperature of 40 K. Only a small influence of modified surface structures on critical heat flux was observed for the pressure of 120 kPa in the present test section geometry. However, with increased pressure and mass flux, the critical heat flux could be increased up to 29% higher than for the smooth tube using surface structured tubes with micro-channels, porous and oxidized layers. The flow boiling process and the critical heat flux occurrence were visualized by high-speed camera records. Additionally, we characterized the surface wettability behavior of the different tube surfaces using the Wilhelmy method. Concluding from the different characteristics capillary effects and/or increased nucleation site density were assumed to influence the critical heat flux performance.

Wettability alteration of reservoir rocks to gas wetting condition: A comparative study

AbstractProductivity of gas condensate reservoirs reduces significantly due to the near wellbore condensate/water blockage phenomenon. A novel, permanent solution to alleviate this problem is near wellbore wettability alteration of reservoir rocks to preferentially gas wetting conditions; industrial chemical materials are good candidates for this purpose, because of their eco‐friendly characteristics, economical price, and mass production. In this paper, a comparative study is conducted on two industrial fluorinated chemicals, MariSeal 800 and SurfaPore M. Static and dynamic contact angle measurements, spontaneous imbibition, and core flooding tests were conducted to investigate the effect of utilized chemical agents on surface wetting behaviour and fluid flow characteristics of rock samples. Contact angle measurements demonstrate that the liquid phase is changed to a non‐wetting phase after chemical treatment and MariSeal 800 has a greater potential to decrease the surface free energy of the calcite surface. Although both chemicals reveal great potential in static contact angle measurements, further experiments were conducted to distinguish between their abilities. Spontaneous air liquid imbibition tests and endpoint relative permeability measurements approved the potential of utilized chemicals to improve liquid phase mobility and decrease critical condensate saturation, which improve production parameters and reservoir productivity. Liquid phase endpoint relative permeabilities of sandstone core samples were improved by factors of 1.74 and 2.62; furthermore, irreducible liquid phase saturations were decreased by factors of 0.68 and 0.5 using MariSeal 800 and SurfaPore M chemicals. The results of this research help efficient selection of chemical agents for further field applications.

Toward a hydrocarbon-based chemical for wettability alteration of reservoir rocks to gas wetting condition: Implications to gas condensate reservoirs

Recently, wettability alteration has been much attended by researchers for studying well productivity improvement in gas condensate reservoirs. Previous studies in this area only utilized water/alcohol based chemicals for this purpose. While, hydrocarbon nature of the blocked condensate in retrograde gas reservoirs, may motivate application of hydrocarbon based chemical agents. In this study, a new hydrocarbon based wettability modifier is introduced to alter wettability of carbonate and sandstone rocks to preferentially gas wetting condition. Static and dynamic contact angle measurements, spontaneous imbibition and core flooding tests were conducted to investigate the effect of proposed chemical on surface wetting behavior, and fluid flow characteristics at core scale. SEM, EDX, EDX map and FTIR tests are used to characterize the adsorbed chemical layer and also to endorse the adsorption of fluorinated chemicals on both sandstone and carbonate rock surfaces. It is inferred from the results of contact angle hysteresis at different levels of tilt angle that the surface roughness increased as a result of treatment with the new chemical. Measurements of surface free energy of calcite thin section at different tilt angles, by means of dynamic contact angle method, showed a significance decrease due to treatment with the new chemical, the factor of reduction ranges from 0.24 to 0.03. The results of air-water and air-n-decane spontaneous imbibition tests showed remarkable decrease in the ultimate imbibed liquids by a factor of 0.14 and 0.34, respectively. Also, core flooding experiment results demonstrated improvement of liquid phase endpoint relative permeability by a factor of 1.73 as a result of treatment with the proposed chemical fluid. The proposed chemical is miscible with dropped out condensate and does not suffer from instability due to reservoir brine salinity. Effectiveness, as well as hydrocarbon base of the proposed chemical makes it an attractive candidate for possible applications to enhance condensate recovery due to both condensate and water blockage in gas reservoirs by wettability alteration technique.

Combination of laser patterning and nano PTFE sputtering for the creation a super-hydrophobic surface on 304 stainless steel in medical applications

Subsequent host tissue responses to implanted biomaterials that occur immediately after implantation are highly determined by surface events between tissue-implant interfaces and in contact biological fluids. These events are directly affected by biomaterial surface features. The surface of the 304 stainless steel as a high used metallic biomaterials in blood contact medical devices need to hemocompatibility improvement. The hemocompatibility features of the surface are affected by various factors, including physical and chemical properties, particularly wettability. A high level of surface hydrophobicity helps to enhance the hemocompatibility. For this, many surface engineering techniques are used to modify and control surface wettability behavior that can be adapted to improve the hemocompatibility and overall performance of biomaterials.In the present study, a laser patterning model is applied for creation of parallel micro-grooves on the surface of 304 stainless steel in first stage. Secondly, a fluorocarbon thin film has been deposited on the inscribed surface of the steel using polytetrafluoroethylene (PTFE) sputtering. The results show that, by creating a micro-groove pattern on the steel surface, the wettability behavior of the surface will also change and the contact angle will be increased from 80° to almost 111°. Moreover, the deposition of a polymer thin film has led to a decrease in surface energy and, thereby, an increase in hydrophobicity and making a contact angle of 149°. From these finding, it can be concluded that, with simultaneous use of topography and surface chemistry changes, the wettability behavior of the surface has been increased and a high and appropriate level of hydrophobicity has been achieved consequently, that is suitable for hemocompatibilty of blood-contact devices.

Facile, robust and large-scale fabrication method of mechanically durable superhydrophobic PDMS/aerogel coating on fibrous substrates

A simple method was developed for the large-scale fabrication of mechanically durable superhydrophobic surfaces with roughness on the microscale. The method is applicable for a large number of fibrous substrates with different pore sizes. With this method, it is possible to prepare polymeric fibrous substrates with a water droplet (5 μL) roll-off angle of less than 5°. The method developed is based on dip-coating of fibrous substrates in polydimethylsiloxane (PDMS)/toluene solution, followed by the electrostatic spray of aerogel microparticles on the samples. Depending on the PDMS solution concentration, it is possible to obtain a superhydrophobic surface with dual-scale roughness on the microscale. In this article, preparation and characterization of surfaces with electrostatic powder spray on the common fibrous cellulose substrates are provided. Fibrous surfaces obtained were characterized by scanning electron microscopy, energy-dispersive X-ray spectroscopy and static water contact angle measurement. Effects of PDMS/toluene solution concentration on the surface morphology and wettability behavior of surfaces were investigated. We demonstrate the mechanical durability of the surface using high-pressure air flow.

Modification of wetting property of Inconel 718 surface by nanosecond laser texturing

Topographic and wetting properties of Inconel 718 (IN718) surfaces were modified via nanosecond laser treatment. In order to investigate surface wetting behavior without additional post treatment, three kinds of microstructures were created on IN718 surfaces, including line pattern, grid pattern and spot pattern. From the viewpoint of surface morphology, the results show that laser ablated grooves and debris significantly altered the surface topography as well as surface roughness compared with the non-treated surfaces. The effects of laser parameters, such as laser scanning speed and laser power, on surface features were also discussed. We have observed the laser treated surfaces of IN718 showed very high hydrophilicity just after laser ablation under ambient air condition. And this hydrophilic property has changed rapidly to the other state, very high hydrophobicity over about 20days. Further experiments and analysis have been carried out so as to investigate this phenomenon. Based on the XPS analysis, the results indicate that the change of wetting property from hydrophilic to hydrophobic over time may be due to the surface chemistry modifications, especially carbon content. After the contact angles reached steady state, the maximum water contact angle (WCA) for line-patterned and grid-patterned surfaces increased to 152.3±1.2° and 156.8±1.1° with the corresponding rolling angle (RA) of 8.8±1.1° and 6.5±0.8°, respectively. These treated IN718 surfaces exhibited superhydrophobic property. However, the maximum WCA for the spot-patterned surfaces just increased to 140.8±2.8° with RA above 10°. Therefore, it is deduced that laser-inscribed modification of surface wettability has high sensitivity to surface morphology and surface chemical compositions. This work can be utilized to optimize the laser processing parameters so as to fabricate desired IN718 surfaces with hydrophobic or even superhydrophobic property and thus extend the applications of IN718 material in various fields.

Modifying the surface wetting behavior of soda-lime silicate glass substrates through thermal poling

Thermal poling, i.e., exposure of a glass to a DC electrical field at moderate temperature, enables the generation of an anisotropic surface layer. Cation motion on the anode side results in the formation of an internal gradient in the electrical potential which can be frozen-in upon cooling. This is accompanied with a change in the polarity of the anode surface and, hence, a change in surface wettability. In this article, we study the effect of thermal poling on the wettability of soda-lime silicate glasses. We confirm a poling-induced increase in surface hydrophobicity on the air-side of commercial float glass, with a water wetting angle increase of around 20° for poling at 210°C and 1.5kV. The effect is persistent after storage for three months under ambient conditions. Significant variation between air and tin-side of the float glass indicates strong compositional dependence and offers a route for tailoring the surface chemical properties of functional glass substrates.

Mimicking lizard-like surface structures upon ultrashort laser pulse irradiation of inorganic materials

Inorganic materials, such as steel, were functionalized by ultrashort laser pulse irradiation (fs- to ps-range) to modify the surface’s wetting behavior. The laser processing was performed by scanning the laser beam across the surface of initially polished flat sample material. A systematic experimental study of the laser processing parameters (peak fluence, scan velocity, line overlap) allowed the identification of different regimes associated with characteristic surface morphologies (laser-induced periodic surface structures, grooves, spikes, etc.). Analyses of the surface using optical as well as scanning electron microscopy revealed morphologies providing the optimum similarity to the natural skin of lizards. For mimicking skin structures of moisture-harvesting lizards towards an optimization of the surface wetting behavior, additionally a two-step laser processing strategy was established for realizing hierarchical microstructures. In this approach, micrometer-scaled capillaries (step 1) were superimposed by a laser-generated regular array of small dimples (step 2). Optical focus variation imaging measurements finally disclosed the three dimensional topography of the laser processed surfaces derived from lizard skin structures. The functionality of these surfaces was analyzed in view of wetting properties.

Recent theoretical development in confined liquid-crystal polymers

Liquid-crystal polymers in confined system is a fundamental issue in soft matter. Theoretical method plays animportant role in studying these systems. The intention of this work is to give a thorough reviewof the theoretical methodologies used in tackling confined liquid crystals. At first, some basic concept of liquid crystal, such as a vital order parameter for orientation, phases of liquid crystal, the uniaxial and biaxial of liquid crystal, are presented. After that, a brief review of the development of liquid-crystal theories, which include the Onsager model, the Maier-Saupe model, the McMillanmodel, the Landau-de Gennes expansion, the Frank elastic model and the self-consistent field model for liquid-crystal polymers, are given. All these theories havetheir own advantages and disadvantages. For example, the phenomenological Frank elastic model is the most widely used model due to its simplicity. In contrast, parameters in the self-consistent field model are physically meaningful, however, it is rather complicated. During recent decades, with these theories and suitable boundary treatment, plenty confined liquid crystal systems are investigated. In this review, we focus on three kinds of confined systems: 1) the surface wetting behavior in slits; 2) the two-dimensional liquid crystals confined by a boundary line and 3) defects in the orientational field of rigid rods on spherical surface. Results arrived from different At the end of this review, we give a list of frontier issues and an outlook for thecoming ten years.

Influence of hydrogen bonding interactions on the properties of ultraviolet‐curable coatings

ABSTRACTPhenolic novolac type epoxy resin has been modified with acrylic acid (AA) and 2‐acrylamido‐2‐methyl‐1‐propanesulfonic acid (AMPS) to form ultraviolet‐curable coatings, and integrated performances of the coatings were evaluated. It was found that the hydrogen bonding interactions among the oligomers became stronger along with the increase of AMPS content, thus the oligomer viscosity and a variety of polymer properties were affected. The polar hydrogen bond donors significantly enhanced the adhesion strength and surface wetting behavior of the coatings. Meanwhile, hydrogen bonding interactions can also reinforce the three‐dimensional structure of the film as in polymeric state, which potentially increased its glass transition temperature and mechanical properties. Results of chemical resistance showed that coatings modified with moderate amount of AMPS could be completely removed in several minutes when exposed to alkali solution or anhydrous ethanol. With these attractive features, modified films had prospective applications in temporary protective coatings. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43113.
