Fabrication of core-shell polyacrylate latex pressure sensitive adhesives modified by fluorinated monomer and film properties

In this work, a series of fluorinated core-shell polyacrylate latex pressure sensitive adhesives (PSAs) were successfully synthesized through monomer-starved seeded semi-continuous emulsion polymerization. Specifically, (meth)acrylate monomers were employed as the main materials, with dodecafluoroheptyl methacrylate (DFMA) were used as modified monomer. The impact of fluorine monomer DFMA on the resulting core-shell latex and PSA properties was thoroughly examined. FTIR analysis confirmed the successful incorporation of DFMA into the latex copolymer through emulsion polymerization. TEM images illustrated that the morphology of latex particles exhibit a distinct core-shell structure. The results also showed that with the addition of DFMA, the water absorption and water whitening of the latex films decreased, while the water contact angle and thermal stability are improved. Interestingly, the latex films with DFMA added to the shell phase exhibit a larger WCA value when compared to those with DFMA in the core phase, further confirmed by XPS results. Finally, the adhesive properties of the fluorinated core-shell acrylate PSA were evaluated. The results of shear strength and gel content demonstrate that the prepared PSA exhibits excellent cohesive properties. Thus, this work could present a feasible strategy for optimizing the comprehensive properties of acrylate latex PSAs.

Hierarchical nanoengineered emulsion with robust adhesion enables superior self-cleaning cotton fabrics

Self-cleaning treatment is of vital importance for the practical application of functional cotton fabrics. However, developing highly efficient, eco-friendly, and durable hydrophobic and oleophobic treatment agents still remains a great challenge. Herein, inspired by the design of the inorganic–organic nanonetwork, we successfully synthesized a novel core–shell structured emulsion of nano-SiO2/fluorine-silicon polyacrylate through semi-continuous emulsion polymerization. The introduction of long-chain alkyl methacrylate octadecyl ester within the shell phase results in a more organized arrangement of fluorine atoms on the surface of cotton fabrics, leading to a rapid reduction in the surface free energy of latex film. The sample is optimized with 20 wt% dodecafluoroheptyl methacrylate and 1 wt% SiO2. The nanoengineered emulsion exhibits strong adhesion and effectively transforms the hydrophilic cotton fabrics into hydrophobic (143.2°) and oleophobic (121.6°) materials. Besides, the self-cleaning characteristic can withstand 25 laundering cycles and 800 abrasion cycles with enhanced robustness. This work opens up a pathway to develop effective, green but long-lasting amphiphobic agents for functional fabrics and sustainable textiles.

Zwitterionic stabilized water-borne polymer colloids for antifouling coatings

This study presents antifouling waterborne (meth)acrylic coatings prepared through seeded semi-continuous emulsion polymerization, using trace amounts of a zwitterionic monomer 2-(methacryloyloxy)ethyl dimethyl-(3-sulfopropyl)ammonium hydroxide (DMAPS). DMAPS was introduced with a dual purpose, to establish a protective layer of DMAPS containing polymer chains on the films' surface, thereby imparting antifouling characteristics, while simultaneously provides in-situ colloidal stability to the emulsion during polymerization.By providing colloidal stability to (meth)acrylic polymer particles in aqueous dispersion (latex), DMAPS-rich units are distributed on the surface of the polymer particles and subsequently on the surface of the resulting polymer films. Subsequent analysis revealed that the films exhibited diminished hydrophilicity, a more textured surface, and diminished affinity for water entrapment compared to conventionally stabilized (meth)acrylic films. Such surfaces demonstrated high resistance to fouling and weak adhesion of the studied BSA protein. These effects were positively influenced by the quantity of DMAPS incorporated within the (meth)acrylic films that allow higher coverage with DMAPS rich polymer chains.The proposed methodology not only emphasizes a potent pathway for the development of environmentally-conscious, waterborne film-forming coating technology but also involves the simultaneous integration of a zwitterionic surface layer, conveying remarkable antifouling attributes to the resulting (meth)acrylic coating film.

Investigating the effect of methacrylic acid on the properties of waterborne epoxy-acrylate core-shell emulsion, film and coating

Waterborne coating has recently become a trend in research, with extensive studies focusing on waterborne epoxy-acrylate (WEA) emulsion. However, the understanding of the role of methacrylic acid (MAA) in the core-shell structure, affecting film and coating performance, is still limited. Here, we investigate the effect of MAA addition on the properties of the WEA core-shell emulsion, film and coating. The WEA core-shell emulsion was synthesized through semi-continuous emulsion polymerization and subsequently cast into WEA film. Two types of crosslinking systems were established by introducing MAA to either the shell layer (interlayer crosslinking) or the core layer (intralayer crosslinking). The interlayer crosslinking provides a high crosslinking density (7.01 × 10−4 mol cm−3), involving the crosslinking of polymer chains between the core and shell layers. Consequently, the film has a compact structure and high modulus (489 MPa) but low elongation at break (3.20 %). Conversely, the intralayer crosslinking has a low crosslinking density (1.59 × 10−4 mol cm−3). Hence, the film has a loose structure and low modulus (0.38 MPa) but high elongation at break (225 %). This occurs because it involves crosslinking with the polymer chains within the same layer, resulting in reduced compatibility between the layers. The inclusion of MAA enhances the clarity in discerning two glass transition temperatures (Tg). Lastly, the stability (shelf-life) of the WEA emulsion remains unaffected by the MAA, with the decisive factor being the presence of the oxirane ring in the Epoxy (EP). We believe that this finding can significantly contribute to a better understanding of the role of MAA in crosslinking systems within WEA core-shell coatings for researchers.

The core-shell structured aqueous dispersions of the siloxane-grafted polyurethane copolymers with high transparency

We have synthesized the siloxane-grafted polyurethane copolymers aqueous dispersions by semi-continuous emulsion polymerization. The mono-methacryloxypropyl terminated polydimethylsiloxane was used to react with the acrylate-terminated waterborne polyurethane, which served as seed emulsions. It is obtained that the as-synthesized copolymer dispersions are stable and have small particle sizes ranging from 77 nm to 120 nm, and they possess core-shell structures. Moreover, the results show that the prepared films exhibit high transparency and hydrophobic surface. Moreover, the enrichment of siloxane and the heterogeneous structure on the film surface was studied. The results of Raman spectra disclose that the intensities of siloxane on the surface change over time during the film formation. These results are correlated to the pressure difference of droplets and low surface tension of siloxane segments. The as-synthesized dispersions promise to be applied in the displayer coatings.

Ultraviolet-magnetic response multicolored janus colloidal photonic crystal beads for information coding

We report a new kind of ultraviolet (UV)-magnetic response Janus colloidal photonic crystal (CPC) beads for information coding. The Janus beads made up of fluorescent CPCs and Fe3O4 nanoparticles show different colors under visible light, UV light and magnetic stimulation. In the concrete scheme, monodisperse colloidal particles with and without fluorescent molecule SPMA were prepared by semi-continuous emulsion polymerization. Then colloidal particles and Fe3O4 nanoparticles were paired as precursors to prepare Janus beads by the droplet template method. During the slow self-assembly process, Fe3O4 nanoparticles were deposited on the bottom and colloidal particles filled the other parts of the beads so that a Janus structure formed. Therefore, the upper surface of Janus beads appears structural color and the lower surface appears black. The variation of Fe content in different hemispheres allows the controllable magnetic response to reverse the beads. The presence of fluorescent molecule SPMA makes fluorescent Janus beads (FJBs) emit fluorescence under UV light. According to design, an array in a particular arrangement of Janus beads can realize reversible changes between three different optical information. Furthermore, the binary cipher was combined with Janus beads to design and fabricate an optical encoding array, revealing an important application in information coding.

Effect of Fluorinated Comonomer, Polymerizable Emulsifier, and Crosslinking on Water Resistance of Latex Coatings

Common latex coatings suffer from poor water resistance, which often limits their practical application. This paper reports on the preparation of polyacrylate latexes using various approaches to tune the water resistance, wettability, and surface properties of their coating films. The mutual effects of fluorinated monomer copolymerization, emulsifier type (polymerizable and general), and intra- or interparticle covalent crosslinking (due to allyl methacrylate copolymerization and a keto-hydrazide reaction, respectively) were studied. The polyacrylate latexes were synthesized through a two-step semicontinuous emulsion polymerization of 2,2,2-trifluoroethyl methacrylate, butyl acrylate, methyl methacrylate, and methacrylic acid as the basic monomers. The fluorinated monomer was incorporated into the second-step polymer (at a content of 30 wt.% based on the second-step monomer feeds). The water resistance, wettability, and surface properties of the coating films were evaluated with focus on the water absorption, water whitening, water contact angle, and surface topography using atomic force microscopy. It was found that highly water-resistant and hydrophobic coatings that possessed a self-healing ability were prepared, provided that the polymerizable emulsifier and the fluorinated monomer were involved in the latex synthesis, along with the intra- and interparticle covalent crosslinking.

Synthesis of tertiary amine functionalized Multi-Stimuli-Responsive latex nanoparticles by semicontinuous emulsion Polymerization: Investigation of responsivities and antimicrobial activity

Stimuli-responsive core–shell nanoparticles (CSNPs) are an important class of smart polymers, which their physical and chemical properties could be changed in response to induced external stimuli. In this study, the amphiphilic CSNPs were synthesized via semi-continuous seeded emulsion polymerization using dimethylamino ethyl methacrylate (DMAEMA) as a hydrophilic monomer, and styrene as a hydrophobic monomer. Developed CSNPs were obtained in two series, poly(N, N-dimethylamino ethyl methacrylate) (PDMAEMA)-polystyrene (PS) core–shell particles and PS-PDMAEMA core–shell particles. The PDMAEMA chains exhibited different responsivities towards temperature rising, pH change, and CO2-gas, which their smart behaviors were investigated by dynamic light scattering (DLS) analysis. The temperature-responsivity of CSNPs was confirmed by observed particle size variation in the case of PDMAEMA-PS (increase) and PS-PDMAEMA (decrease) core–shell latex particles, when temperature increased to 70 °C, above the lower critical solution temperature (LCST) of PDMAEMA. Protonation of tertiary amine functional groups in the presence of CO2 bubbling led to an increase in the size of CSNPs as a result of water swelling of PDMAEMA chains. On the other hand, the size of CSNPs was changed in acidic (pH = 4) and basic (pH = 10) media by swelling and deswelling of PDMAEMA located in the core or shell. Obtained results indicated that maximum antimicrobial activity was observed for PS-PDMAEMA CSNPs compared to PDMAEMA-PS, which is probably due to presence of the PDMAEMA on the surface and increase of positive charge related to amine groups in this sample. The developed antimicrobial latexes have potential applications for using as antibacterial additives in water-based coatings and adhesives.

Designing of desired nanocomposite pressure-sensitive adhesives through tailoring the structural characteristics of polysilsesquioxane-acrylic core-shell nanoparticles

A series of novel nanocomposite pressure-sensitive adhesives (PSAs) made of core-shell nanoparticles has been designed with a diverse range of adhesion properties from general-purpose to high-shear adhesives. The PSAs were prepared by synthesis of polymethacryloxypropylsilsesquioxane (PSQ) nanoparticles and their encapsulation with an acrylic shell via semi-continuous emulsion polymerization. The effects of structural characteristics of the core-shell nanoparticles, i.e. composition of acrylic comonomers in the shell, shell thickness, and grafting density, on peel and shear strengths of the PSAs were scrutinized. Grafting of acrylic chains on the surface of PSQ nanoparticles led to an improvement in the peel and shear strengths due to enhancement in the dynamic mechanical moduli. Increase in the cohesive energy density of the PSAs through raising the methyl methacrylate content in the shell enabled designing of high peel and shear PSAs. Increasing the number of segments of the grafted chains present in the semi-dilute polymer brush (SDPB) region through 40% enlargement in the shell thickness of the nanoparticles decreased the peel and shear strengths. However, increasing the grafting density through a 4.5-fold rise in the core size and thus extension of the concentrated polymer brush region and elimination of SDPB region led to an extraordinary 1400-fold improvement in the shear strength. • Grafting of acrylic chains on PSQ enhanced peel and shear strengths simultaneously. • Optimization of cohesive energy density of shell enhanced peel and shear strengths. • Extension of semi-dilute polymer brush region deteriorated the shear strength. • Increase in grafting density led to an extraordinary improvement in shear strength.

High performance demulsifiers for heavy crude oil based on alkyl acrylic-amino alkyl acrylic random bipolymers

• Novel demulsifiers for heavy and extra-heavy crude oils based on acrylic monomers. • Chemical demulsifiers to treat and destabilize complex crude oil emulsions. • Superior dehydrating and clarifying capacity to that of polyethers formulations. • DPD simulation to stablish the dehydrating mechanism of new acrylic demulsifiers. In this work, a series of novel random alkyl acrylic-amino alkyl acrylic bipolymers was synthetized by semi-continuous emulsion polymerization technique. The obtained bipolymers were characterized mainly by Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), 1D and 2D nuclear magnetic resonance (NMR) and size exclusion chromatography (SEC). Afterwards, these bipolymers were evaluated as demulsifying agents in four heavy crude oils. The evaluations revealed that the efficiency of the synthesized acrylic bipolymers to break the emulsion, induce the drop coalescence and clarify the remaining aqueous phase depends strongly on their alkyl acrylic/amino alkyl acrylic ratio in the chain and average molecular mass. Likewise, it could be noted in three samples of heavy crude oils from Motul field that a greater content of the amino alkyl acrylate monomer in the bipolymer chain and a higher molecular mass allowed reaching higher emulsion removal efficiencies, with good water clarification. It was also shown that, in all the cases, a single acrylic bipolymer is able to remove the water dispersed in petroleum in a more efficient way than a commercial formulation of four triblock bipolymers based on ethylene and propylene oxide, when it possesses convenient structural features. In addition, for a better understanding of the improved dehydrating efficiency of the new acrylic demulsifiers reported in this study, a mechanism of bridge formation between water drops to provoke coalescence was established by dissipative particle dynamics (DPD) simulation. This theoretical technique was also applied to calculate the decrease of the interfacial tension as a function of the number of alkyl acrylic-amino alkyl acrylic chains at the water/crude oil interface.

Polymer nanolatexes for dyeing of soybean fabric

AbstractIn this study, functionalized polymer nanolatexes based on P(MMA‐co‐BA‐co‐MAA) are synthesized by semicontinuous emulsion polymerization. An evaluation of the effect of reaction parameters such as monomer composition and initiators type on the latex properties is performed. Consideration of these effects allows the synthesis of low surfactant concentration‐high functionalized polymer nanoparticles as small as 29 nm. Then, a functionalized nanolatex is used as a binder in dyeing process of soybean protein fabric (SBF) using the cationic dye, Basic Red 46. Colorimetric tests show that the previous functionalization of soybean fibers with the nanolatex improves the efficiency of dyeing process by up to 13%. In addition, washing and rubbing fastness tests revealed that dyed functionalized fabrics had better performance than the one without nanolatex.

Screen-printed photochromic textiles with high fastness prepared by self-adhesive polymer latex particles

Photochromic textiles have received increasing attention due to their wearable properties and reversible discoloration. However, improving the poor fastness of photochromic textiles is always a problem. In this paper, the self-adhesive polymer (PSBM-SP) latex particles based on spiropyran were prepared and then applied to obtain photochromic textiles with high fastness. The PSBM-SP latex particles were prepared via semi-continuous emulsion polymerization of styrene (St), n-butyl acrylate (BA), vinyltrimethoxysilane (VTMS), and a self-synthesized polymerizable photochromic monomer (SPMA). The chemical structure of SPMA was confirmed by 1H NMR and FT-IR. Results of UV–vis spectra indicated that the discoloration and fading process of PSBM-SP latex particles can be completed within 120 s and 150 s under ultraviolet and visible irradiation, respectively. The PSBM-SP latex particles retained good photochromic properties after the alternating ultraviolet and visible light for irradiation 30 times. Then, the PSBM-SP latex particles were used to prepare the screen-printed photochromic textiles by the chemical crosslinking and film formation, which showed softer hand feel and better fastness than the conventional printing with a large number of binders. Importantly, the prepared photochromic textiles had a fast UV-response performance and maintained impressive reusability after experiencing 30 washing cycles, proving their great potential in wearable and flexible textile-based photochromic materials.

Process Characterization of Polyvinyl Acetate Emulsions Applying Inline Photon Density Wave Spectroscopy at High Solid Contents.

The high solids semicontinuous emulsion polymerization of polyvinyl acetate using poly (vinyl alcohol-co-vinyl acetate) as protective colloid is investigated by optical spectroscopy. The suitability of Photon Density Wave (PDW) spectroscopy as inline Process Analytical Technology (PAT) for emulsion polymerization processes at high solid contents (>40% (w/w)) is studied and evaluated. Inline data on absorption and scattering in the dispersion is obtained in real-time. The radical polymerization of vinyl acetate to polyvinyl acetate using ascorbic acid and sodium persulfate as redox initiator system and poly (vinyl alcohol-co-vinyl acetate) as protective colloid is investigated. Starved–feed radical emulsion polymerization yielded particle sizes in the nanometer size regime. PDW spectroscopy is used to monitor the progress of polymerization by studying the absorption and scattering properties during the synthesis of dispersions with increasing monomer amount and correspondingly decreasing feed rate of protective colloid. Results are compared to particle sizes determined with offline dynamic light scattering (DLS) and static light scattering (SLS) during the synthesis.

The influence of a non-isocyanate urethane monomer in the film formation and mechanical properties of homogeneous and core-shell latexes

A urethane methacrylate monomer, 2-((methylcarbamoyl)oxy)ethyl methacrylate, (MEM), was synthesized via a non-isocyanate pathway and incorporated into latexes using a semi-continuous emulsion polymerization. Homogeneous and core-shell latexes were prepared using MEM, methyl methacrylate (MMA) and butyl acrylate (BA). Narrow particle size distribution and high conversion was achieved for all latexes. Core-shell structure was corroborated by differential scanning calorimetry (DSC), dynamic mechanical thermal analysis (DMTA) and transmission electron microscopy (TEM). Thermal properties, viscoelastic, mechanical properties and morphology were evaluated and compared as a function of increasing concentration of the urethane methacrylate monomer. Enhanced viscoelastic and mechanical properties were obtained with higher MEM content in both homogeneous and core-shell latexes. Incorporation of MEM into latexes lowered the minimum film formation temperature (MFFT) and also enhanced the extent of film formation. Core-shell latexes displayed higher storage modulus, Young's modulus, tensile strength and hardness compared to homogeneous latexes due to the combination of hard core and the pendent urethane present in the continuous phase (shell).

Redox initiation in semicontinuous polymerization to search for specific mechanical properties of copolymers

AbstractIn this work, for a semicontinuous emulsion polymerization reaction, it is shown that using a redox initiation system at 40°C, substantial modifications in copolymer chain composition with conversion can be easily obtained. To test controllable trajectories for comonomer feeding, linear and parabolic profiles were chosen to get different types of chain composition variations for the 50/50 w/w styrene/n-butyl acrylate system. For the “forced composition copolymers,” the molecular weight averages and distribution were obtained by size exclusion chromatography. The composition along conversion was followed by proton nuclear magnetic resonance to determine the weight composition distribution (WCD) of the copolymer chains. Mechanodynamic (dynamic-mechanical analysis), tensile, and hardness tests exhibited consistent results depending on the WCD that outcomes from the respective feeding profile. The results confirm that this methodology is of great potential for industrial applications when looking for synergy in copolymer properties, and low-cost processes.

Fabrication of industrial-level polymer photonic crystal films at ambient temperature Based on uniform core/shell colloidal particles

HypothesisPolymer photonic crystals have drawn a lot of interest due to cost-effective fabrication. Although tremendous efforts are tried, almost no large-size photonic crystal (PC) films can be obtained due to different kinds of reasons. The main issues are the tedious process and strict preparation conditions (like high temperature and solvents), sometimes the limitation of the machinery equipment, accordingly they are not conducive to preparation of subsequent large-scale PC films. Hence, there is an urgent desire to develop a technique that can assemble polymer PC films in a large scale at low temperature without solvent. ExperimentsThrough semi-continuous emulsion polymerization, core-interlayer-shell (CIS) colloidal particles (PS@PEA@P2EHA) were synthesized with the output of 240 g/h. After the successful production of polymer PC films in the laboratory at room temperature, industrial roll-to-roll process was used for large-scale production of the PC films. FindingsBy introducing poly(2-ethylhexyl acrylate) which has quite low glass transition temperature (Tg) into the shell, we have successfully developed an energy-efficient technique for fabrication of large-area (over 100 m2) polymer PC films at ambient temperature for the first time. This technique has great potential to promote the industrial application of PC films, such as display, sensors, anti-counterfeiting and so on.

Thermal and mechanical properties of cationic starch-graft-poly(butyl acrylate-co-methyl methacrylate) latex film obtained by semi-continuous emulsion polymerization for adhesive application

In this work, thermal and mechanical properties of cationic cassava starch-g-poly(butyl acrylate-co-methyl methacrylate) films with different amounts of cationic cassava starch (CCS) were studied. The objective of this work was to substitute a portion the monomers (BA/MMA) by CCS in the copolymer and to investigate the consequent effects on the properties of the polymer latex films (e.g., graft percentage, surface tension, thermal and mechanical properties). The results show that the grafting percentage decreased as the concentration of CCS increased. Thermal and mechanical properties of polymer films showed a direct relationship with respect to the content of CCS used and the grafting percentage. Higher grafting percentage led to improvement of the thermal degradation, which indicated better thermal stability than neat poly(BA/MMA). DSC analysis showed that the Tg of the graft copolymers was a little lower as compared to Tg values of un-grafted copolymers. The addition of CCS increases the tensile, elastic modulus and hardness properties of the polymer film, but the elongation at break decreased dramatically. The optimal CCS contents that maximized not only thermal properties, but also mechanical properties, were 7 and 10 mass%, which are directly related to the grafting percentage and CCS content in the formulation. In addition, these results create a new approach for the application of CCS graft-polymer as an adhesive for wood, paper and shoes insole applications.

Effect of dodecafluoroheptyl methacrylate (DFMA) on the comprehensive properties of acrylate emulsion pressure sensitive adhesives

Fluorinated acrylate emulsion pressure sensitive adhesives (PSA) based on butyl acrylate (BA), fluorine monomer dodecafluoroheptyl methacrylate (DFMA), acrylic acid (AA) and 2-hydroxyethyl acrylate (HEA) were synthesized via a monomer-starved seeded semi-continuous emulsion polymerization process. The influences of DFMA on the resultant latex and PSA properties were comprehensively investigated. FTIR analysis indicated that DFMA could be successfully introduced into the latex PSA copolymer through emulsion polymerization. DSC and TG analyses showed that Tg and thermal stability of the PSA were both improved as DFMA content increased. XPS analysis indicated that fluoroalkyl groups had a tendency to enrich on the surface of the film, and the more DFMA added the more F content on the film surface. Moreover, the surface roughness and contact angle of the acrylate latex PSA film were both increased with the introduction of DFMA. Dynamic mechanical analysis (DMA) and adhesive property tests showed that the storage modulus (Gʹ) and shear holding power were improved with DFMA content while at the sacrifice of loop tack. Finally, 180° peel strength of fluorinated acrylate latex PSAs on different substrates (PP, SS) as a function of DFMA content was evaluated.

Environmentally Friendly Water-Based Self-Crosslinking Acrylate Dispersion Containing Magnesium Nanoparticles and Their Films Exhibiting Antimicrobial Properties

A water-based polymeric acrylate dispersion (latex) containing MgO nanoparticles, which had been added at a concentration of 1.5% (with respect to the monomers) during the preparation procedure, was investigated as an environmentally friendly binder for sanitary interior paints. The properties of this new latex were compared to those of a reference system free of the magnesium nanoparticles, synthesized by the same route, i.e., by semi-continuous emulsion polymerization. Tests were made in order to ascertain the mechanical and chemical properties, flash corrosion resistance and antimicrobial effect of the latex films. The results revealed that the new latex containing magnesium nanoparticles provided solvent-resistant coating films having pronounced antimicrobial activity against all the tested bacterial and fungal strains. The desirable antimicrobial properties can be ascribed to the sharp-edged character of magnesium nanoparticles, the peroxidation of lipids and the formation of reactive oxygen species. Moreover, no flash corrosion was formed beneath coating films containing magnesium nanoparticles, which can be attributed to the alkaline action due to the dissolution of a fraction of MgO in latex medium. The results of all of the tests provided evidence of the superiority of the polymeric dispersion with the magnesium nanoparticles to the reference system containing no nanoparticles.

Waterborne coatings based on acrylic latex containing nanostructured ZnO as an active additive

This work was devoted to the study of the properties of an acrylate latex-based binder synthesized by semicontinuous emulsion polymerization. Nanoparticles of zinc oxide (NPsZnO) in an amount of 1.5 wt% with respect to the polymer content were added to the binder during the synthesis procedure. The binder was then homogenized with various anticorrosion pigments, fillers, and additives to obtain model anticorrosion paints. In addition, model paints with expected enhanced antimicrobial resistance designed for the protection of mineral substrates were also formulated and prepared. The effects of NPsZnO on the physicomechanical properties and on the chemical, anticorrosion, and antimicrobial resistance of the paint films were examined. The properties of the paints based on the synthesized binders were also compared to those of a commercial acrylate-type binder. The results show that incorporation of NPsZnO into the latex during the synthesis provided stable polymeric dispersions exhibiting physicochemical, mechanical, and anticorrosion properties that were superior to those of a blank binder (containing no nanoparticles) as well as to the commercial binder. It was also demonstrated that the binder with NPsZnO provided anticorrosion paints that are usable as coatings for environments with a moderate corrosion burden as well as paints for interior applications with reduced biocide contents.
