Therefore, taking advantage of the positive effects of multilayer structure of a-zirconium phosphate (α-ZrP) on the anti-aging properties of coatings, organic–inorganic composite materials based on a-ZrP were synthesized. Firstly, a-ZrP was synthesized by a hydrofluoric acid precipitation method. Then, CT-ZrP was prepared by a-ZrP, pre-intercalated successively with cholamine and cetyltrimethylammonium bromide (CTAB). The synthesized CT-ZrP was then used for synthesizing urushiol-titanium polymer/ZrP composite coatings (M-ZrP) through intercalation. The results of XRD, TEM, and FTIR proved the successful intercalation of α-ZrP and the loss of layering M-ZrP composite coatings in the process of exfoliation. TG results showed that the thermal stability of M-ZrP3 (3 wt% CT-ZrP) was higher than that of urushiol-titanium polymer (UTP). After 1000 h of accelerated aging, 3 wt% of CT-ZrP could significantly improve the anti-aging property of the UTP coating, and the maximum rate of gloss loss was the lowest (5.9%).

Conventional acrylic resin emulsion and organic silane hybridized acrylic resin emulsion prepared by emulsion polymerization were mixed with colloidal silica to form organic-inorganic composite films. The addition of colloidal silica to emulsions yielded films with higher hydrophilkities, as indicated by lower water contact angles for these films in comparison to films without colloidal silica. The water contact angles of organic silane hybridized acrylic resin emulsion/colloidal silica films were lower than those of acrylic resin emulsion/colloidal silica films. Composite films containing colloidal silica particles smaller than 100 nm in diameter showed high hydrophilicities. Observations of the dispersed state of colloidal silica particles in organic-inorganic composite films by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) demonstrated that colloidal silica particles were densely aggregated on the film surface. Outdoor exposure tests of the coating materials prepared from organic silane hybridized acrylic resin and colloidal silica particles with diameters of 7.5 nm showed excellent stain resistance.

Traction (mécanique)Index. décimale : 667.9 Revêtements et enduits Résumé : A series of ambient self-crosslinkable acrylic resin/protein composite emulsions (PA–Ps) were prepared by copolymerizing the functional monomer acetyl acetylethyl methacrylate (AAEM) with methyl acrylate, butyl acrylate and acrylic acid, and then protein crosslinking agents such as gelatin and casein were also added. The PA–P films were characterized by Fourier transform IR spectroscopy, contact angles, differential scanning calorimeter, thermogravimetric analysis, antisolvent testing and physicomechanical testing. Influences of AAEM and protein dosages on properties of composite films were examined in detail. The results indicate that influences of AAEM and protein on PA–P films are diverse on solvent resistance, physicomechanical properties and thermal properties. With enhancement of AAEM and protein dosages, hardness, solvent resistance to tetrahydrofuran and glass transition temperature (Tg) of PA–P films are markedly enhanced, but the decomposing temperatures (Td) are decreased. Tensile strengths are evidently reinforced while elongations at break are lessened. Suitable AAEM and protein dosages could render PA–P films with good water resistance.

Caractérisation
ChitosaneLe chitosane ou chitosan est un polyoside composé de la distribution aléatoire de D-glucosamine liée en ß-(1-4) (unité désacétylée) et de N-acétyl-D-glucosamine (unité acétylée). Il est produit par désacétylation chimique (en milieu alcalin) ou enzymatique de la chitine, le composant de l'exosquelette des arthropodes (crustacés) ou de l'endosquelette des céphalopodes (calmars...) ou encore de la paroi des champignons. Cette matière première est déminéralisée par traitement à l'acide chlorhydrique, puis déprotéinée en présence de soude ou de potasse et enfin décolorée grâce à un agent oxydant. Le degré d'acétylation (DA) est le pourcentage d'unités acétylées par rapport au nombre d'unités totales, il peut être déterminé par spectroscopie infrarouge à transformée de Fourier (IR-TF) ou par un titrage par une base forte. La frontière entre chitosane et chitine correspond à un DA de 50 % : en deçà le composé est nommé chitosane, au-delà, chitine. Le chitosane est soluble en milieu acide contrairement à la chitine qui est insoluble. Il est important de faire la distinction entre le degré d'acétylation (DA) et le degré de déacétylation (DD). L'un étant l'inverse de l'autre c'est-à-dire que du chitosane ayant un DD de 85 %, possède 15 % de groupements acétyles et 85 % de groupements amines sur ses chaînes.
Le chitosane est biodégradable et biocompatible (notamment hémocompatible). Il est également bactériostatique et fongistatique.
Le chitosane est également utilisé pour le traitement des eaux usées par filtration ainsi que dans divers domaines comme la cosmétique, la diététique et la médecine.

ViscoseIndex. décimale : 667.9 Revêtements et enduits Résumé : Regenerated cellulose fibers—viscose fibers—were coated with chitosan using an ultrasound technique to improve their accessibility, reactivity and sorption properties. The main purpose of our research was to study the modification of viscose fibers and to determine the effect of the application of chitosan onto viscose fibers. Samples were obtained by treating the fibers with chitosan in a dilute acetic acid solution in an ultrasonic bath. The influences of the chitosan coating on the changes in morphology, supramolecular structure, sorption and tensile properties were studied. The spectra (FTIR analysis) of the treated viscose fibers showed changes and new absorption bands that revealed the existence of the chemical interactions with the chitosan. The scanning electron microscope images confirmed that the surface of the fibers was covered with the chitosan. A decrease in the water retention value and increase in the absorption and moisture content with an increasing concentration of chitosan was noted. Furthermore, the differences in tensile behavior were analyzed using an Instron tensile testing machine. The chitosan coating had no effect on the tensile strength of the viscose fibers, but influenced the tensile strain. Some changes, though not significant, were noted in the structure (crystallinity, orientation) of the treated viscose fibers.
