Transparence (optique)Index. décimale : 667.9 Revêtements et enduits Résumé : An acrylic copolymer containing epoxy groups was synthesized by free radical polymerization of glycidyl methacrylate, methyl methacrylate and butyl acrylate. Afterwards, polyhexamethylene guanidine hydrochloride (PHMG) was chemically bonded with the resin through a reaction between the epoxy groups of the resin and the amino groups of PHMG to generate non-leaching and permanent antimicrobial acrylic coating. When the content of PHMG reaches 1.0 wt%, the inhibition factors against E. coli and S. aureus were respectively 99.992% and 99.994%, and the antimicrobial coating retains an excellent antimicrobial property even after being laundered with detergent solution. Moreover, the hydrophilicity of the antimicrobial coating was increased after the introduction of polar PHMG.

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Fluoroalkyl end-capped 2-acrylamido-2-methylpropanesulfonic acid oligomer/poly(vinyl alcohol) composite [RF-(AMPS)n-RF/PVA] films were prepared by casting homogeneous aqueous methanol solutions containing RF-(AMPS)n-RF/PVA composites, which were prepared by the reactions of the corresponding oligomer with PVA. The transparent colorless RF-(AMPS)n-RF/PVA composite films thus obtained were subjected to tensile testing to evaluate the values of Young’s modulus, tensile strength, and elongation at break. The RF-(AMPS)n-RF/PVA composites films are capable of greater Young’s modulus than the original PVA film (PVA/HCl film), which was prepared by casting the aqueous methanol solution of PVA in the presence of 1 N hydrochloric acid. The polymer film bearing a higher Young’s modulus is, in general, tough and brittle to providing lower elongation at break; however, we can observe a significant increase in both the tensile strength and elongation at break of the RF-(AMPS)n-RF/PVA composite films, compared to those of the PVA/HCl film. In addition, it was demonstrated that the RF-(AMPS)n-RF/PVA composite films can exhibit a higher water adsorption ability than that of the PVA/HCl film. Note de contenu : - Measurements

VinyltriméthoxysilaneIndex. décimale : 667.9 Revêtements et enduits Résumé : Hydrophilic poly(vinyl alcohol) (PVA) was chemically modified by using fluoroalkyl end-capped vinyltrimethoxysilane oligomer [RF-(VM)n-RF] to lead the PVA/RF-(VM)n-RF composite films. The PVA/RF-(VM)n-RF composite film obtained under non-catalytic conditions was found to provide the water-soluble property; however, the acidic conditions enabled the composite film to afford no solubility toward water, giving an amphiphobic property on both the surface and reverse sides just after the deposit of an oil or water droplet. RF-(VM)n-RF oligomer was also applied to the fabrication of the PVA/RF-(VM)n-RF/B(OH)3 composite film by using the RF-(VM)n-RF/B(OH)3 nanocomposites, which were prepared by the composite reaction of RF-(VM)n-RF oligomer with boric acid. It was demonstrated that the PVA/RF-(VM)n-RF/B(OH)3 composite film obtained by the interaction of the corresponding nanocomposites with PVA under acidic conditions can afford the perfect water-resistance ability even after immersion of this film into water for 30 min to give the amphiphobic property on both the surface and reverse sides, although the corresponding PVA/RF-(VM)n-RF composite film and the pristine PVA film provided the swelling behavior toward water, respectively. Thermal gravimetric analyses (TGA) and differential thermal analyses (DTA) measurements showed that the PVA/RF-(VM)n-RF/B(OH)3 composite film can give a higher thermal stability than that of the RF-(VM)n-RF/PVA composite film and the pristine PVA film.

SiliceLa silice est la forme naturelle du dioxyde de silicium (SiO2) qui entre dans la composition de nombreux minéraux.
La silice existe à l'état libre sous différentes formes cristallines ou amorphes et à l'état combiné dans les silicates, les groupes SiO2 étant alors liés à d'autres atomes (Al : Aluminium, Fe : Fer, Mg : Magnésium, Ca : Calcium, Na : Sodium, K : Potassium...).
Les silicates sont les constituants principaux du manteau et de l'écorce terrestre. La silice libre est également très abondante dans la nature, sous forme de quartz, de calcédoine et de terre de diatomée. La silice représente 60,6 % de la masse de la croûte terrestre continentale.
VerreIndex. décimale : 667.9 Revêtements et enduits Résumé : Fluoroalkyl end-capped vinyltrimethoxysilane oligomer [RF–(CH2CHSi(OMe)3)n–RF; RF = fluoroalkyl group; n = 2, 3] can undergo the sol–gel reactions in the presence of a variety of phosphonic acid derivatives such as 1-hydroxyethylidene-1,1-diphosphonic acid, nitrilotris(methylene phosphonic acid), and 2-phosphonobutane-1,2,4-tricarboxylic acid under alkaline conditions to provide the corresponding fluorinated oligomeric silica/phosphonic acids nanocomposites. Interestingly, it was demonstrated that the modified glasses and filter papers treated with these obtained fluorinated nanocomposites can exhibit the superoleophobic/superhydrophilic and superoleophilic/superhydrophobic characteristics on their surfaces, respectively. More interestingly, the modified filter papers treated with these nanocomposites were applied to the separation of the mixture of oil and water. Note de contenu : - EXPERIMENTAL : Measurements

Traction (mécanique)Index. décimale : 667.9 Revêtements et enduits Résumé : Ultraviolet (UV)-curable coatings made from acrylated epoxy soybean oil (AESO) combine the advantages of renewable biobased resources and energy-efficient UV-curable materials, so they serve as the primary research objects for developing eco-friendly coatings. However, due to the lack of rigid structure, the hardness and thermal stability of AESO are much lower than those of petroleum-based epoxy acrylate (EA). Therefore, high-performance soybean oil-based UV-curable oligomers were prepared by using dimethylolpropionic acid (DMPA) and methacrylic anhydride (MAAH) to modify ESO and then blended with high-functional active diluent trimethylolpropane triacrylate (TMPTA). Furthermore, FTIR, 1H NMR, and GPC were used to analyze the molecular structure and molecular weight of the oligomers. The oligomers (DMA/MAAESO and DMA/MAAESO-TM) had high esterification rate, curing degree, and good storage stability. The cured coatings from DMA/MAAESO and DMA/MAAESO-TM oligomers had significantly improved thermal stability, tensile, and coating properties. In all samples, DMA/MAAESO-TM cured coating had excellent coating performances. The glass transition temperature (Tg) of DMA/MAAESO-TM was 78.1°C, and its crosslink density (νe) was 6.87 × 10−3 mol/cm3. The hardness, curing time, gloss, flexibility, and impact resistance were H, 20 s, 108.5, 1 mm, and 50 cm, respectively.
