Nanoparticules -- SynthèseIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Leather finishing is a very important operation in leather manufacture. Various chemicals are used in leather finishing. The introduction of nanoparticles in leather finishing has revolutionized the leather industry. They are used to produce various types of leathers and to meet the end user requirements. The aim of the work was to coalesce the fields of leather technology and nanotechnology for obtaining superior quality of leather with improved performance. Synthesis of titanium metal oxide nanoparticles was done by sol-gel process and used in leather finishing mixture as coating ingredients. The physical and chemical properties of the synthesized metal oxide nanoparticles were characterized by TEM, FE-SEM, EDAX, FT-IR and XRD. The surface morphology of the nanoparticle coated leather was evaluated by AFM. The finished leather was assessed for its film adhesion to evaluate the strength of the bonding between the leather surfaces and finish coating. The conventional finish system experience finish adhesion issue in due course of time. The titanium metal oxide nanoparticles coated leather exhibited increased adhesion property. TiO2 nanoparticles increased the intermolecular linkages between the leather finish coating and the leather surface. Note de contenu : EXPERIMENTAL :

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.
Séparation (technologie)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Developing high-performance separation membrane with good durability is a highly desired while challenging issue. Herein, we reported the successful fabrication of chemically and mechanically durable superhydrophobic membrane that was prepared by embedding UiO-66 as size-sieving sites within the supramolecular fiber structure of collagen fiber membrane (CFM), followed by the polydimethylsiloxane (PDMS) coating. The as-prepared CFM/UiO-66(12)/PDMS membrane featured capillary effect-enhanced separation flux and homogeneous porous channels guaranteed high separation efficiency. When utilized as double-layer separation membranes, this new type of composite membranes separated various surfactant stabilized water-in-oil microemulsions and nanoemulsions, with the separation efficiency high up to 99.993 % and the flux as high as 973.3 L m− 2 h− 1. Compared with commercial polytetrafluoro ethylene (PTFE) membrane, the advantage of the double-layer CFM/UiO-66(12)/PDMS membranes in separation flux was evident, which exhibited one order of magnitude higher than that of commercial PTFE membrane. The CFM/UiO-66(12)/PDMS membrane was acid-alkali tolerant, UV-aging resistant and reusable for emulsion separation. Notably, the CFM/UiO-66(12)/PDMS membrane was mechanically durable against strong mechanical abrasion, which was still capable of separating diverse water-in-oil emulsions after the abrasion with sandpaper and assembled as double-layer separation membranes. We anticipate that the combination of CFM and metal organic frameworks (MOFs) is an effective strategy for fabricating high-performance separation membrane with high mechanical and chemical durability.

Pigments inorganiquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Nanocrystalline cobalt aluminate spinel, CoAl2O4, was prepared via a microwave-assisted solution combustion process applying various mixtures of urea, glycine, and starch as a novel mixed fuel. The effects of starch addition (0, 10, 20, and 30 wt%) on the physical characteristics (e.g. crystallite size and colour) of the blue nano pigments were also investigated. The resultant powders were characterised by means of X-ray diffraction, scanning electron microscopy, electron dispersive X-ray analysis, and CIE L*a*b* colour measurements. The presence of a CoAl2O4 spinel lattice after calcination of precursors at 600 °C was confirmed by X-ray diffraction patterns, and the crystallite sizes were ca. 10–39 nm. Colorimetric data pointed to the formation of bright-blue pigments at low levels of starch addition. Scanning electron microscope images showed that starch enrichment reduced the agglomeration and size of synthesised nanoparticles. Note de contenu : - EXPERIMENTAL : 1. Powder synthesis - 2.

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.
Technique des plasmasIndex. décimale : 668.4 Plastiques, vinyles Résumé : We demonstrate a commercialized injection molding method for nano patterning of polymethyl methacrylate (PMMA) for the purpose of mass production of a label-free optical biosensor chip. Scanning electron microscope (SEM) images clearly show uniform nanopattern transfer on the plastic chip fabricated by an injection molding method. A uniformly deposited silicon nitride layer having a high refractive index by a plasma enhanced chemical vapor deposition (PECVD) technique is also observed. A unique characterization method is described wherein optical resonance reflection is used accurately and quickly to characterize the geometrical sensor structure. The authors anticipate that this robust method will provide an excellent means of producing an optical resonance reflection biosensor (ORRB).

The optical properties of the PBAE/ATO composites were analyzed by fabricating thin films on glass substrates. The polymeric film with 3 wt% ATO showed good transparency in the visible and UV regions and strong absorption in the NIR region. Moreover, under light illumination, the PBAE/ATO thin film displayed an ~ 24.4°C rise in temperature relative to the reference thin film. In addition, the outdoor NIR absorption efficiency was studied by spray coating a PBAE/ATO thin film over a vinyl greenhouse, and it was observed that the PBAE/ATO-coated greenhouse prevented snow deposition during the winter by melting the snowflakes through NIR absorption.
