Enhanced anti-icing performance of novel superhydrophobic F-L@KH-SiO2/OTMS coating synergistic preparation with bionic micro-nano structures and modified nanoparticles

Surface icing significantly impacts equipment operation and safety in low-temperature environments. Passive de-icing technologies using superhydrophobic materials are gaining attention for their environmental and cost benefits. This study presents a novel superhydrophobic F-L@KH-SiO2/OTMS coating, fabricated through femtosecond laser etching of aluminum alloy to create bionic micro-nano lattice structures. Subsequently, a hydrophobic epoxy coating was sprayed as an adhesive layer, followed by chemical modification of the ablated aluminum alloy surface using 3-(trimethoxysilyl) propyl methacrylate (KH570) modified silicon dioxide (SiO2) nanoparticles, γ-aminopropyltriethoxysilane (KH550), and octadecyltrimethoxysilane (OTMS) as hydrophobizing agents. The resulting coating exhibits excellent superhydrophobic properties, with a contact angle (CA) of 165.92° and a sliding angle (SA) of only 1.25°. The coating demonstrated superior anti-adhesion and bouncing capabilities, effectively preventing droplet freezing and ice formation, which is attributed to the synergistic effect of the modified silica and the cross-linked lattice structure. Compared to other reported superhydrophobic surfaces, this coating showed a longer freezing delay time of 730 s at −20 °C. These findings highlight the potential of the F-L@KH-SiO2/OTMS coating for efficient anti-icing, de-icing, and defrosting applications.

Preparation of polyaniline‐aniline modified silicon dioxide composite with synergistic anticorrosion effect for waterborne epoxy anticorrosive coatings

AbstractOwing to environmental friendliness, waterborne coatings have attracted considerable attention for the protection of mechanical equipment. Herein, polyaniline (PANI)‐aniline modified silicon dioxide (ANSiO2) composite was prepared to improve the corrosion resistance of waterborne epoxy coatings through the modification of SiO2 nanoparticles by aniline‐methyl‐triethoxysilane and the subsequent in situ polymerization of aniline (AN). When the molar ratio of AN to ANSiO2 was 6:1, the obtained PANI‐ANSiO2 composite appeared spherical‐planar shape and was able to obviously improve the anticorrosive performance of the epoxy coatings. The impedance value of the PANI‐ANSiO2 composite modified coatings maintained above 108 Ω cm2 after being immersed in 3.5 wt% NaCl solution for 30 days, and the surface of the coating had no corrosion spread after 30 days of salt spray erosion test. The excellent anticorrosive effect of the PANI‐ANSiO2 was mainly attributed to not only the filling of the defective parts of the coatings by hydrophobic ANSiO2 but also the formation of passivation layer on the coating surface by PANI to impede electrochemical corrosion reaction. The preparation method in this work is facile, low‐cost, and easy produced on a large scale, and the environment friendly high‐anticorrosion coating shows great application potential in the field of metal protection.

Development of fluorosilicon bivalve isocyanate microcapsules for multifunctional coatings with excellent self-repairing properties, enhanced hydrophobicity, and corrosion protection properties

This study first self-made TMP-IPDI tetramer, and then prepared a fluorine-modified silicon dioxide double shell isocyanate type self-healing microcapsule (CBS-X/TMP-IPDI@PU@F-SiO2) using TMP-IPDI tetramer, fluorescent agent 4,4-bis (2-disulfonic acid sodium styrene) biphenyl (CBS-X) as the core material, polyurethane (PU) as the single shell, and fluorine modified silicon dioxide (F-SiO2) as the double shell using interfacial polymerisation method. Then, it was added to waterborne polyurethane (WPU) to prepare self-healing coatings and coatings. The chemical structure, microstructure, self-healing self detection, and mechanical properties of TMP-IPDI, CBS-X/TMP-IPDI@PU@F-SiO2, and composite coatings were characterized by infrared spectroscopy (FTIR), proton nuclear magnetic resonance (1H NMR), scanning electron microscopy (SEM), particle size analysis (PSA), X-ray electron spectroscopy (XPS) analysis, contact angle testing, tensile testing, electrochemical impedance testing, and Ultraviolet photograph. The results showed that the TMP-IPDI tetramer was successfully prepared. The average particle size of CBS-X/TMP-IPDI@PU@F-SiO2 prepared is 29 μm. The contact angle, tensile strength, low-frequency impedance and Nyquist curve radius of the repaired spots increased with the increase of the amount of CBS-X/TMP-IPDI@PU@F-SiO2 in WPUs; the increasing trend slowed down when the amount of CBS-X/TMP-IPDI@PU@F-SiO2 was >5 %. When the CBS-X/TMP-IPDI@PU@F-SiO2 dosage is 5 %, the WPU coating has good self-repair and self-detection performance. The stress before and after repair were 12.89 MPa and 20.11 MPa, respectively, with a repair rate of 80.3 %. The contact angle at the repair site can reach 100.8°, and the coating has good corrosion resistance. The microcapsules prepared based on fluorine-modified silica (F-SiO2) as the wall material have good self-healing performance for WPU coatings, achieving secondary protection of the repaired material.

Molecular mechanism of the improved adhesion between PDMS adhesive and silicon substrate after thermal treatment

An interesting experimental observation recently found that thermal treatment of polydimethylsiloxane (PDMS) adhesives and the contact adhesion time can significantly improve the interfacial adhesion. However, the mechanism underlying such adhesion enhancement is unclear. To disclose the micro-mechanical mechanism of the adhesion improvement, contrast experiments are systematically carried out with PDMS adhesives respectively adhering on silicon and silicon dioxide substrates in the present paper. For the case of thermal treatment of PDMS adhesives while on the substrates, the adhesion strength of a PDMS adhesive on a silicon substrate is significantly stronger than that on a silicon dioxide substrate after thermal treatment at different temperatures, and the adhesion strength on both substrates increases with increasing thermal treatment temperature and contact time. For the case of first thermally treating the PDMS adhesive and then adhering to the silicon substrate, the adhesion strength is much smaller than that of thermally treating PDMS adhesives while on silicon substrates. This is mainly because the migration and restructuring of the PDMS molecular chains form intimate contact between the PDMS adhesive and substrate after thermal treatment. Meanwhile, high temperature could lead to the easy formation of hydrogen bonds at the interface between the PDMS adhesive and silicon substrate. The surface of silicon provides more favorable conditions to form hydrogen bonds than the silicon dioxide surface, leading to the stronger adhesion of PDMS adhesives on silicon substrates after thermal treatment. If the silicon dioxide surface is modified and grafted with hydroxyl (–OH) groups, which are one of the main groups forming hydrogen bonds with the PDMS material, the adhesion strength of the PDMS adhesive on the modified silicon dioxide substrate is approximately the same as that on the silicon substrate after thermal treatment. The results obtained in the present study could provide a new and convenient design strategy to achieve strong attachment without any surface microstructures.

Surface Modified Silicon Dioxide Based Functional Adsorbents Derived From Waste Sand for the Removal of Toxic Pollutants From Water

Nanoparticle Mediated Treatment of Dairy Wastewater

Nanotechnology is one of the emerging areas of scientific interest with numerous applications. In this research, surface modified silicon dioxide nanoparticules have been developed from low molecular weight chitosan by dip-coating technique for the batch treatment of dairy wastewater. The processing parameters of wastewater pH, mixing duration, agitation speed and quantity of nanoparticles are varied, and the treatment efficiency was established by measuring the total dissolved solids (TDS), turbidity, chemical oxygen demand (COD), total suspended solids (TSS), and dissolved oxygen (DO). Dynamic light scattering (DLS), scanning electron microscopy (SEM), energy dispersive X-Ray analysis (EDX), and fourier transform infrared spectrocopy (FTIR) are employed as characterization techniques. The DLS analysis showed the average diameter of the nanoparticles as 320 nm and the EDX analysis confirmed the elemental composition of the silicon dioxide nanoparticles. The functional groups are identified by FTIR. The optimum values for the best treatment conditions are established as pH 3.0, 60 minutes contact time, 100 rpm agitation speed and a nanoparticle dosage of 0.6 g. The batch expérimental study démontrâtes that the surface modified silicon dioxide nanoparticles could efficiently remove the polluants from the dairy wastewater in an environmentally friendly and cost effective method.

Protein adsorption on amino-acid-conjugated self-assembled molecule-modified SiO2 surfaces

Protein adsorption has a crucial effect on biocompatibility during the interaction of biomaterial surfaces and the biological environment. It is significant to understand and control the interactions among biomaterials and proteins for several biomedical applications. Surface engineering plays a significant role in determining biocompatibility by tuning the effects directly on proteins. In this study, amino acid (histidine and leucine) conjugated self-assembled molecules were synthesized and used to modify silicon dioxide (SiO2) surfaces to investigate protein adsorption behavior. Silicon dioxide surfaces were modified with (3-aminopropyl)triethoxysilane-conjugated histidine and leucine amino acids. Modified silicon dioxide surfaces were characterized by water contact angle measurements and X-ray photoelectron spectroscopy analysis. Protein adsorption (human serum albumin, fibrinogen and immunoglobulin G) on silicon dioxide-coated crystals was investigated in situ by using a quartz crystal microbalance (QCM) biosensor. From the results, model proteins showed different selectivities to the amino-acid-conjugated silicon dioxide-coated crystals depending on the type of the amino acid and concentration. Consequently, this controlled chemistry on the surface of biomaterials has a great potential to manipulate protein adsorption and enhance the biocompatibility of biomaterials for various biomedical applications.

A facile graphene oxide modified approach towards membrane with prominent improved permeability and antifouling performance

The superior hydrophilicity of graphene oxide (GO) makes it a promising candidate for improving the permeability and antifouling performance of membranes used for feed water pretreatment in desalination systems. However, the uncontrollable assembly structures of GO laminates on membrane surface restrict the full exertion of its hydrophilicity. In this study, a layer-by-layer self-assembled GO-based nanocomposite membrane with adjustable interlayer spacing and assembly layers was facilely fabricated by alternately depositing GO and (3-Aminopropyl) triethoxyilane modified silicon dioxide (SiO2@APTES) on membrane surface via electrostatic interaction. The fully exerted hydrophilicity of GO and well-maintained membrane pore structures facilitated the adsorption and penetration of water molecules, meanwhile, the hydration layer and electronegativity of GO effectively inhibited the adhesion of foulant. Thus, monolayer GO/SiO2@APTES/GO endowed P-(G/S/G)1 membrane with more than 10-fold water flux (560.2 L m−2 h−1) than pure PVDF membrane (55.4 L m−2 h−1) without sacrificing selectivity; and the antifouling performance was improved by nearly 50%. Moreover, the nanocomposite membrane presented robust structural stability after physicochemical cleaning. Overall, the nanocomposite membrane affords a novel facile way to fully exert the hydrophilicity of GO to improve permeability and antifouling performance, and is expected to provide an important guarantee for efficient operation of desalination system.

The Effect of Silicon Dioxide Nanoparticles Combined with Entomopathogenic Bacteria or Fungus on the Survival of Colorado Potato Beetle and Cabbage Beetles.

Three types of modified silicon dioxide nanoparticles (SiO2, 10–20 nm) with additives of epoxy, silane and amino groups, used independently and in combination with the entomopathogenic bacteria Bacillus thuringiensis subsp. morrisoni and fungus Metarhizium robertsii were tested against Colorado potato beetle (Leptinotarsa decemlineata) and cabbage beetles (Phyllotreta spp.). All three nanoparticles were found to have an entomocidal effect on Colorado potato beetle larvae and crucifer flea beetles when ingested. Increased susceptibility of insects to B. thuringiensis or M. robertsii blastospores and their metabolites was shown after exposure to the modified silicon dioxide nanoparticles. The potential of modified silicon dioxide nanoparticles to enhance the efficiency of biopesticides based on the bacteria B. thuringiensis and fungi M. robertsii is considered in the paper.

HIGHLY EFFICIENT FIRE-EXTINGUISHING POWDER

Fire-extinguishing powders based on ammonium phosphates (FEP) have a high specific fire-extinguishing ability. However, during storage, their technical characteristics deteriorate, which reduces the efficiency to extinguish fire. To solve this problem, the authors have considered a promising direction for improving the technical properties of FEP by using superhydrophobic functional additives based on silicon dioxide particles. The paper discusses methods for manufacturing fire-extinguishing powder using superhydrophobic silicon dioxide particles with different textural and structural properties and apparent contact angles more than 160°. Based on the results of rheological tests, the main characteristics of functional additives (particle size, shape, apparent contact angle) were determined. Their influence on the fire-extinguishing efficiency of FEP was proven. It was shown that the addition of modified silicon dioxide with monodisperse spherical particles (~55nm) into the FEP provides high flowability, superhydrophobicity (apparent contact angel 168°) and low moisture absorption. The developed functional additive made it possible to manufacture FEP that demonstrates the best among analogues characteristics of fire-extinguishing efficiency, moisture resistance and flowability.

Potential for significantly improving comprehensive performance of oil-well cement by a new type of latex

In this study, a new type of soap-free inorganic/organic composite latex (SBML-II) was prepared by soap-free emulsion polymerisation method using sodium p-styrenesulfonate (SSS) and modified silicon dioxide as copolymer emulsifiers, which were characterised by Fourier transform infrared spectrometer, transmission electron microscope, thermo-gravimetric analysis and other means. Then the latex was employed to prepare polymer latex modified oil-well cement, and the influence of the latex on the basic properties of cement slurry, mechanical properties and microstructure of cement matrix was evaluated. The characterisation of SBML-II showed that the synthesised latex presents a typical core-shell structure and possesses better dispersibility, stability and thermal stability than conventional latex (SBML-I). At the same time, the SBML-II latex forms a membranous morphology more easily than SBML-I at the same temperature and has better compatibility with additives and resistance to ions. Performance evaluation in cement slurry and cement matrix showed that the SBML-II has a good dilution effect on cement slurry and excellent potential to improve the mechanical properties of the cement matrix. Meanwhile, the addition of SBML-II is helpful to improve microstructure, owing to film formation in the cement matrix.

Novel long-chain aliphatic polyamide/surface-modified silicon dioxide nanocomposites: in-situ polymerization and properties

A new kind of long-chain aliphatic polyamide (PA1218) with a relatively low melting point, high molecular weight, and stable mechanical properties at humid conditions was successfully developed via a polycondensation reaction between 1,18-octadecanedioic acid and 1,12-diaminodecane. Additionally, oleic acid-surfaced modified silicon dioxide (SSD) was prepared and employed to improve the properties of PA1218 through in-situ polymerization. FT-IR spectra and TGA thermograms confirmed the successful surface modification of nanoparticles, and consequently, 5% substitution of surface hydroxyl groups of SiO2 nanoparticles with oleic acid molecules. Moreover, the thermomechanical and rheology tests revealed a significant improvement in nanocomposites’ properties compared to the pure PA1218; for instance, the tensile strength and storage modulus were increased by 22% and 40%, respectively in the sample containing 3% SSD nanoparticles. This improvement, along with SEM images, confirmed the uniform dispersion of SSD nanoparticles through the employed in-situ polymerization and excellent compatibility between inorganic and organic phases, which was achieved via surface modification. Finally, all the samples demonstrated a water uptake capacity of less than 0.6% attributed to the high methylene/amide ratio in their backbones, causing these newly developed nanocomposites to be notable candidates for specific engineering applications.

Thermal and mechanical properties of poly(lactic acid) filled with modified silicon dioxide: importance of the surface area

In this research work, the effect of the change in the surface area of silicon dioxide nanoparticles of the same size on mechanical properties of poly(lactic acid) nanocomposites (PLA) was studied, as well as the role of coupling agent amount in the compatibility of these nanomaterials. We consider a spherical silicon dioxide with a surface area of 170–200 m2/g (labeled as S–SiO2) and another considered amorphous with a surface area of 180–600 m2/g (labeled as P-SiO2). This surface areas difference plays an important role in modifying of nanoparticles polarity by incorporating a coupling agent and its integration into partially polar polymers. According to obtained results, for nanomaterials with high surface area, it was observed while increasing coupling agent amount, the elasticity of the composite was observed to increase. In contrast, in nanomaterials with spherical nanoparticles, it was observed that as the amount of coupling agent decreases, the resistance of the material increases, reaching a maximum when a 10:2 ratio is used. It was observed that behaviors for both nanoparticles were different, which gives an idea that the incorporation of nanoparticles in polymers is not an issue of coupling agent or quantity only, it is more important as it is arranged on the surface. This kind of couplings does not only affect mechanical properties, since the thermal behavior of the material was also influenced, where it was observed that particles with low surface area modify the crystallization rate when they have different percentages of coupling agent on the surface. Furthermore, it is observed that the incorporation of nanoparticles with high surface areas area does not modify the crystallization rate significantly. Besides, in both cases, it was observed that the highest crystallization rate is reached when a 10:2 ratio is used. However, the energy required to form crystals remains unchanged. Therefore, it is considered that the incorporation of nanoparticles only affects the crystal formation rate without disturbing the energy requirement for crystal formation. Finally, a maximum in the 10:2 ratio was observed for the compatibility in both particles, which was manifested in an increase in the storage module through a dynamic mechanical analysis. The rate of crystal formation as well as the number of formed crystals have a considerable effect on mechanical properties of nanocomposites when the surface area is modified.

Effect of chemical interaction at modification layer/substrate interface on molecular orientation of dinaphtho[2,3-b:2′,3′-f]thieno[3,2-b]thiophene thin films

The molecular orientation of dinaphtho[2,3-b:2′,3′-f]thieno[3,2-b]thiophene (DNTT) thin films on modified silicon dioxide (SiO2) and copper oxide (CuOx) substrates whose surfaces were treated by 6-[(3-trisilanol)propylamino]-1,3,5-triazine-2,4-bis(2-aminoethylamine) (TAS) was investigated using near-edge X-ray absorption fine structure and ultraviolet/X-ray photoelectron spectroscopy. The standing orientation of DNTT was obtained in DNTT/TAS/SiO2 and DNTT/TAS/CuOx. The amount of amorphous region in DNTT/TAS/SiO2 was larger than that in DNTT/TAS/CuOx. The TAS treatment on the substrates formed interfacial dipoles at TAS/SiO2 and TAS/CuOx interfaces by chemical interaction, resulting in the vacuum level shift by −0.9 and −1.2 eV, respectively. Functional groups at the outermost TAS surface were amino groups in TAS/SiO2 and silanol groups in TAS/CuOx. The intermolecular distance of DNTT was widened in DNTT/TAS/SiO2 because of an electrostatic repulsion with nitrogen. The interfacial dipole at the modification layer/substrate interface and functional groups at the modified surface affect the molecular orientation of DNTT thin films on the modification layer.

Synthesis and characterization of sodium laurylsulfonate modified silicon dioxide for the efficient removal of europium

With the development and utilization of nuclear energy, radioactive contamination has caused special concern. Herein, the sodium laurylsulfonate modified silicon dioxide (SLS/SiO2) was prepared to eliminate europium (Eu) from aqueous solution. The SLS/SiO2 composite revealed a uniform spherical structure. The results showed that Eu(III) removal onto SLS/SiO2 was monolayer adsorption, and the elevated temperature was advantageous to Eu(III) removal. The adsorption capacity of SLS/SiO2 at 298 K reached 52.5 mg/g for Eu(III), and the adsorption of Eu(III) was dependent on solution pH and independent on coexisting ions. The adsorption of Eu(III) reached the adsorption equilibrium within 120 min, showing a great advantage. The retention of Eu(III) onto SLS/SiO2 only occurred at the surface of the composite. According to the characterization analysis, the removal mechanism was the strong surface complexation of Eu(III) at the surface of SLS/SiO2. The results in this study can offer significant information for the radioactive pollution control.

Chitosan modified silicon dioxide composites for the capture of graphene oxide

Graphene oxide (GO) is considered as a toxic carbon material, and the adverse impact of GO has been realized. Herein, the spherical chitosan modified silicon dioxide (CS/SiO2) was prepared to eliminate GO. Considering the effects of hydroxyl and amidogen groups, the introduction of chitosan onto silicon dioxide can not only change the morphology and size of the composite but also increase the removal capacity for GO. The experimental results demonstrated that the removal of GO onto the CS/SiO2 composites relied on pH and ionic strength. The maximum removal capacity of CS/SiO2 for GO was 111.8 mg/g, and the elimination of GO was endothermic. Based on the characterization analysis, the electrostatic attraction played the main role in GO removal process. Furthermore, the hydroxyl groups and amidogen groups on the surface of CS/SiO2 formed a hydrogen bond with GO, which was conducive to GO capture. This work promoted the trapping of GO and provided an example for other nanomaterials removal from the aquatic environment.

Superhydrophobic Surface Modified by Sol-Gel Silica Nanoparticle Coating

We reported a superhydrophobic silica-coated surface with a water contact angle of 160° with a 4 μL water droplet, and transparency of 70-86% in the wavelength range of 380-800 nm. The silica film was synthesized at room temperature (22 °C) using sol-gel process by a simple, cost-effective and uniform spin-coating by mixing silicon dioxide sol-gel with γ-(2, 3-epoxypropyloxy) propyltrimethoxysilane (KH-560). The durability of the coating could be effectively enhanced by controlling the ratio of KH-560 and modified silicon dioxide sol-gel. It was believed that this process that we used can hold a great potential in super-hydrophobic surface fabrication.

Enhanced Transmittance Modulation of SiO2-Doped Crystalline WO3 Films Prepared from a Polyethylene Oxide (PEO) Template

Polyethylene oxide (PEO)-modified silicon dioxide (SiO2)-doped crystalline tungsten trioxide (WO3) films for use as electrochromic layers were prepared on indium tin oxide (ITO) glass by the sol–gel spin coating technique. The effects of the PEO template and SiO2 on the electrochromic transmittance modulation ability of crystalline WO3 films were investigated. Fourier transform infrared spectroscopy (FT-IR) spectra analysis indicated that PEO was decomposed after annealing at 500 °C for 3 h. X-ray diffraction (XRD) pattern analysis showed that both SiO2 and PEO helped reduce the crystalline grain size of the WO3 films. Atomic force microscope (AFM) images showed that the combined action of SiO2 and PEO was helpful for achieving high surface roughness and a macroporous structure. An electrochromic test indicated that PEO-modified SiO2-doped crystalline WO3 films intercalated more charges (0.0165 C/cm2) than pure WO3 crystalline films (0.0095 C/cm2). The above effects resulted in a good transmittance modulation ability (63.2% at 628 nm) of PEO-modified SiO2-doped crystalline WO3 films, which was higher than that of pure WO3 crystalline films (9.4% at 628 nm).

Anti-fouling and thermosensitive ion-imprinted nanocomposite membranes based on grapheme oxide and silicon dioxide for selectively separating europium ions

The increasing amount of europium in aqueous environment from rare earth industry has become a serious environmental challenge. Significant efforts have been focused on ion-imprinting membranes (IIMs) for selective separation of ions from analogues. Based on ion-imprinting technique, we have developed Eu3+-imprinted nanocomposite membranes (Eu-IIMs) for selectively separating Eu3+ from La3+, Gd3+ and Sm3+. Polydopamine (pDA) was previously synthesized on basal membranes to augment the interfacial adhesion. Grapheme oxide (GO) and modified silicon dioxide (kSiO2) were synergistically stacked on pDA-modified substrates to form hydrophilic nanocomposite membranes. Ag nanoparticles were modified on the surface to enhance anti-fouling performance. The temperature-controlled selective recognition sites were formed using N-isopropylacrylamide (NIPAm) and acrylamide (Am) as functional monomers as well as europium ions as templates by RAFT (reversible addition-fragmentation chain transfer) method. Large enhanced Eu3+-rebinding capacity (101.14 mg g−1), adsorptive selectivity (1.82, 1.57, 1.45 for Eu3+/La3+, Eu3+/Gd3+, Eu3+/Sm3+) and permselectivity (3.82, 3.47, 3.34 for La3+/Eu3+, Gd3+/Eu3+, Sm3+/Eu3+) were achieved on Eu-IIMs with superior regeneration performance. Additionally, the negligible damage of the membranes after buried for 20 d indicated the superior anti-fouling property of the Eu-IIMs. The ion-imprinted nanocomposite membranes synthesized in this work have shown great potentials for selective separation of rare earth ions.

Surface Grafting of Functionalized Poly(thiophene)s Using Thiol-Ene Click Chemistry for Thin Film Stabilization.

Regioregular poly[(3-hexylthiophene)-ran-(3-undecenylthiophene)] (pP3HT) and vinyl terminated poly(3-hexylthiophene) (xP3HT) were synthesized by the McCullough method and surface grafted to thiol modified silicon dioxide wafers using thiol-ene click chemistry. Utilizing this method, semiconducting, solvent impervious films were easily generated. Thiol-ene click chemistry is convenient for film stabilization in electronics because it does not produce side products that could be inimical to charge transport in the active layer. It was found through grazing incidence wide-angle X-ray scattering (GIWAXS) that there is no change in microstructure between as-spun films and thiol-ene grafted films, while there was a change after the thiol-ene grafted film was exposed to solvent. Organic field-effect transistors (oFETs) were fabricated from grafted films that had been swelled with chloroform, and these devices had mobilities on the order of 10-6 cm2 V-1 s-1, which are consistent with poly(thiophene) monolayer devices.
