Tests d'efficacitéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Sun protection preparations (sunscreens) are classified differently internationally. The Sun Protection Factor (SPF) determination methods as well as the UV filter substances are not harmonised so far. According to all available scientific studies, the UV filters sold in the EU are effective and safe. Further research is necessary to implement sun protection filters in the nano sector. According to the current legislation in Europe one cannot expect the development of new and better biodegradable UV filter substances because necessary animal testing is prohibited and alternative methods are not predictable.

VernisIndex. décimale : 667.9 Revêtements et enduits Résumé : The degree of UV protection afforded by nano-ZnO in a polyurethane/acrylic clear topcoat was investigated. The influence of nano-ZnO concentration and dry film thickness on the optical properties (e.g., UV permeability and visible transmittance) of the coating was probed using a library of 28 samples that were prepared by high throughput techniques. A model for predicting the UV permeability of nano-ZnO filled coatings was developed and the nano-ZnO loading condition required to block >99% UV radiation was determined to be 2.0 g/m2. This model can be used to assist in the development of coatings and other polymeric systems embedded with nano-ZnO to protect the coating and underlying materials (i.e., substrate) from UV degradation.

RhéologieIndex. décimale : 668.4 Plastiques, vinyles Résumé : Polypropylene/organoclay nanocomposites were prepared by melt-mixing in a twin-screw extruder. Polypropylene grafted with maleic anhydride was used as compatibilizer. The evolution of the microstructure along the screw profile was characterized through dead-stop experiments. In order to quantify the multi-scale dispersion state of the nanocomposites, different techniques have been used: scanning electronic microscopy (SEM) to observe the large remaining aggregates, X-Ray diffraction measurements to characterize the intercalation state by measuring the interlamellar distance, and finally rheological characterizations in the molten state to assess the dispersion state at the nanoscale. The effects of low barrel temperatures and high matrix viscosity were tested, in order to improve exfoliation by an increase in shear stresses.

Produits de conservation du cuirIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : Although tanning makes the collagen matrix resilient against microbial attack, the chemicals used in the finishing process are susceptible to microbes. Hence, it is imperative to develop a finishing process with inherent antimicrobial properties. Leathers with antimicrobial properties evoke a considerable array of interest in consumers. The present study aims to enhance the antimicrobial properties of the leather using copper nanoparticles in the finishing and retanning process. Copper nanoparticles have been synthesized by chemical reduction using copper sulphate pentahydrate as the precursor with dialdehyde starch and gallic acid. The prepared nanoparticles have been characterized using UV-Visible spectrometry, dynamic light scattering, scanning electron microscopy, transmission electron microscopy, and X-ray diffraction techniques. The prepared nanoparticles have been used in both retanning and finishing processes. The experimental leather retanned using copper nanoparticles possess good mechanical strength properties and color index value compare to the control. Nanoparticles are effective against both gram negative and positive bacterial organisms. The nanoparticles also inhibit the growth of common fungus, which can colonize on leather. Thus, the current study paves the way for a novel solution that is an alternative to biocides and antimicrobial chemicals and is more effective in inhibiting microbial growth.
