Vapeur d'eauIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : An acrylic resin and an acrylic-resin/nano-SiO2 composite prepared as coating agents were applied in leather finishing and various properties of the finished leathers were determined. The results show that the physicalmechanical properties and cleaning properties of the leather samples finished with the acrylic-resin/nano-SiO2 composite increase noticeably. As examples, water vapour penetration and air permeability improved by 11.5% and 15.4%, dry rub fastness and folding strength [flexing] of the leather finished with the composite resin were also, to a degree, superior to that finished by the acrylic resin. The surface morphology observed by SEM (scanning electron microscope-energy spectrum of X-ray analysis) and AFM (atomic force microscope) indicated that the surface of the leather finished with the composite resin is smoother than that of leathers finished with the acrylic resin.

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 : 675 Technologie du cuir et de la fourrure Résumé : Microbial activity on leather during its storage and use is one of major problems in the leather industry. Micro-organisms cause damage which costs millions of dollars to the global leather industry. Hide and skin suppliers and tanners are aware of the necessity to use antimicrobial products to protect their precious raw material. The control of bacteria and fungi growth is important to prevent and minimize the generation of mal odours and some skin problems as weII. Recently, the leather industry has been exploring the benefits of remarkable properties of nanoparticles with antimicrobial properties.
In this antimicrobial effects of nano silver, nano silver-doped titanium dioxide and silicon dioxide, nano-size silicon dioxide and zirconium oxide on leather material are presented.Note de contenu : - Nanosilver and its antimicrobial activity on leather

PolydiméthylsiloxaneLe polydiméthylsiloxane —[O-Si(CH3)2]n—, ou poly(diméthylsiloxane) selon la nomenclature systématique, communément appelé PDMS ou diméthicone, est un polymère organominéral de la famille des siloxanes souvent présent dans les shampoings. On l'y ajoute pour augmenter le volume des cheveux mais il peut également aller boucher les pores du cuir chevelu et rendre les cheveux gras. C'est une des raisons pour lesquelles se laver les cheveux tous les jours est très déconseillé avec un shampooing contenant des silicones.
Il existe également de l'amodiméthicone, qui est un dérivé du diméthicone.
Le polydiméthylsiloxane est un additif alimentaire (E900), utilisé comme antimoussant dans les boissons (Coca-Cola BlāK).
La chaîne de poly(diméthylsiloxane) forme également la structure de base des huiles et des caoutchoucs silicones.
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.

Résines photosensiblesIndex. décimale : 668.9 Polymères Résumé : This research aims to develop a new dry nano powder inverse imprint technology, and probe into transferring and replication of micro patterns. First, a polydimethylsiloxane (PDMS) mould surface, with micro patterns of grating structures, undergo activation treatment with oxygen plasma in order to improve mould surface energy, and thus, spin coat photoresist onto the surface more easily. Then, the surface is heated to restore its hydrophobicity, and by means of nano powder, micro patterns are transfer printed onto the polymethylmethacrylate (PMMA). Research results show that dry nano powder soft coat transferring and forming technology can accurately reproduce the required patterns. In the experiment, gas assisted nano powder imprint technology is used to apply even pressure, coupled with even temperature rise for solidification, then, patterns can be effectively transfer printed and completely formed. Further, these patterns are in perfect contact with the PMMA surface, thus, greatly increasing the valid imprint area and enhancing transferring reproductiveness. The technology integrates technologies, such as, soft lithography, solidifying photoresist, and gas assisted pressure application, and is utilized to transfer print micro patterns in a grating structure, and thus, complete the transferring process of dry micro structure patterns.

Polymères en émulsionIndex. décimale : 667.9 Revêtements et enduits Résumé : Acrylate latex is widely used in coating film forming agents, textile printing and dyeing adhesives, daily chemical products, medical polymers etc. However, the drawbacks of the acytate, such as poor water resistance, easy brittleness at low temperature and losing adhesion at high temperature have limited its further application. Thus, it is necessary to modify the latex to widen its application. Nowadays, more and more attention has been focused on nanometre-acrylate composite materials, such as silicon dioxide, titanium dioxide, alumina, zinc oxide etc, which have been used in emulsion polymerisation to improve the properties of acrylate latex because of the particular properties of the nanometer materials. In this paper, the modification of acrylate latex with nanometer materials is reviewed in detail, which can bring some inspiration to modification of the acrylate latex.

RutileLe rutile est une espèce minérale composée de dioxyde de titane de formule TiO2 avec des traces de fer (près de 10 % parfois), tantale, niobium, chrome, vanadium et étain. Il est trimorphe avec la brookite et l'anatase. Il est la forme la plus stable de dioxyde de titane et est produit à haute température, la brookite se formant à des températures plus basses et l'anatase formée à des températures encore plus basses.Index. décimale : 667.9 Revêtements et enduits Résumé : Nano-TiO2 pigments in pure crystallographic anatase and rutile phases have been successfully prepared by hydrothermal at 120°C and hydrolysis methods, respectively. The laboratory-prepared pigments were characterized parallel to two commercial pigments of the same crystal structure. All pigments were applied in paper coating mixtures, and their influence on coated paper properties was systematically investigated. X-ray diffraction investigation showed that the laboratory-prepared pigments using the hydrothermal method at 120°C were pure anatase, whereas hydrolysis method produced pure rutile phase pigment. The application of the prepared nanopigments and the corresponding commercial TiO2 phases in paper coating revealed that clay/rutile nano-TiO2 pigments in paper coating mixture decreased coated paper roughness more than blending clay with anatase nano-TiO2 pigments. Commercial nano-TiO2 pigments increased porosity of coated paper at both the 30% and 50% addition of nano-TiO2 pigments to clay, while laboratory-prepared nano-TiO2 pigments highly decreased it at 30% addition of nano-TiO2 to clay, compared to clay only. Blending of clay/nano-TiO2 pigments improved both brightness and opacity of the coated paper where commercial pigments are more effective. Burst, tensile strength, stretching, and TEA were improved in the case of all pigments. The 50% addition of the prepared and commercial nanopigments in conjunction with clay improved the mechanical coated paper properties more than 30% addition (except the cases of stretching and TEA of the commercial pigments). The coated paper samples were offset printed. It was found that blending of clay/nano-TiO2 pigments improved print density. Commercial nano-TiO2 pigments improved print gloss more than the laboratory-prepared ones. This result was found consistent with the results of coated paper roughness.
