Polyméthacrylate de méthyleLe poly(méthacrylate de méthyle) (souvent abrégé en PMMA, de l'anglais Poly(methyl methacrylate)) est un polymère thermoplastique transparent obtenu par polyaddition dont le monomère est le méthacrylate de méthyle (MMA). Ce polymère est plus connu sous son premier nom commercial de Plexiglas (nom déposé), même si le leader global du PMMA est Altuglas International9 du groupe Arkema, sous le nom commercial Altuglas. Il est également vendu sous les noms commerciaux Lucite, Crystalite, Perspex ou Nudec.

ZirconeLe dioxyde de zirconium ou oxyde de zirconium(IV) couramment appelée zircone est un composé inorganique du zirconium de formule ZrO2. Ce matériau est une céramique technique d'aspect opaque. Appelé CZ (Cubic Zirconia) lorsque transparent, il est utilisé pour imiter le diamant. Il ne faut pas le confondre avec le zircon (ZrSiO4). Sous sa forme tétragonale, l'oxyde de zirconium est un matériau a vocation mécanique, cette évolution cristallographique lui confère une dureté très élevée (1200Hv) ainsi qu'une bonne résistance aux sollicitations mécaniques (700Mpa en traction et 2000Mpa en compression). Une fois polie, la zircone tétragonale peut atteindre un Ra de 0,02, ce qui permet de l'utiliser pour des pièces de frottement.Index. décimale : 667.9 Revêtements et enduits Résumé : Zirconia nanoparticles synthesized by the sol–gel method were surface modified by the coupling agent, 3-(trimethoxy silyl) propyl methacrylate (MSMA), containing C=C bonds. These particles were then UV-cured together with the hexa-functional monomer, dipentaethritol hexaacrylate (DPHA), to prepare transparent coatings that exhibited antistatic property on plastic substrates. FTIR and solid 29SiNMR were used to analyze the chemical bonds in the formed particles and coatings. Dynamic light scattering measurement of the modified ZrO2 sol indicated a relatively small particle size distribution, 1.5–20 nm, with a maximum intensity at ~5.5 nm. These particles dispersed uniformly in the organic host, poly(DPHA), as was manifested by the high resolution SEM images of the coatings. Antistatic performance of the coatings was examined based on the surface resistivity measurements. A resistivity of 7.74 × 108 ?/? suited to common antistatic applications could be attained for coatings containing 10% inorganic component. In addition, all of the prepared coatings were very hard with pencil hardness 7H–8H, and they attached perfectly to the PMMA substrate according to the peel test.

The results revealed that the surface tensions of water were decreased to 21–34 mN · m–1when applying these surfactants at a concentration range from 10–3to 10–4mol · L–1. Moreover, the performance of foaming, emulsification, anti-static and rewetting of the surfactants were investigated and the results showed that both the rewetting and emulsifying ability of the prepared surfactants were much better than that of conventional surfactants. In addition, the anti-static and foaming properties were also improved at the same condition compared to that of conventional surfactants.

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : In this study, a facile and cost-effective approach has been developed for fabricating antibacterial and antistatic waterborne polyurethane (WPU)-based coatings by using Polyaniline-Copper@Zinc oxide (P-Cu@ZnO) ternary nanohybrid as a multifunctional additive. The solid-state reaction of copper acetate and zinc acetate salts led to the synthesis of copper clusters on the ZnO nanoparticles (Cu@ZnO). The obtained Cu@ZnO nanoparticles were intercalated with polyaniline (PANI) chains to prepare the P-Cu@ZnO nanohybrid. FTIR, XRD, UV–Vis, and FESEM analyses were used to characterize the structural, crystallographic, and morphological properties of the synthesized nanohybrid. Adding P-Cu@ZnO nanohybrid to the WPU matrix not only improved adhesion strength of the coatings but also enhanced their scratch resistance compared to the pristine WPU coating. Moreover, incorporation of the obtained nanohybrid into the WPU coatings caused electrical surface resistance of the obtained coatings to reach 1.2 × 10+8 Ω/sq, so, these coatings gained the optimum electrical surface resistance to be counted as an antistatic coating. Also, the results of the colony counting test showed that the modified coatings could reduce the Staphylococcus aureus and Escherichia coli bacteria growth by about 86% and 74%, respectively.
