Séparation de phasesIndex. décimale : 667.9 Revêtements et enduits Résumé : We experimentally examined the time-evolutions of local compositions in photocurable, monomer-solvent-initiator ternary liquid film coatings using attenuated total-reflectance-Fourier transform infrared spectroscopy. The coatings exhibited phase separation upon UV exposure owing to the inherent partial miscibility between the solvent and the polymer. The solvent concentration at the bottom of the coating increased when exposed to UV light for 1 s from the top, showing a solvent transport along the irradiation direction. The differences in solvent concentration before and after UV exposure showed good agreement with model predictions based on stress-induced non-Fickian solvent mass transport. The solvent concentrations at the bottom remained constant in the case of discrete phase structures, whereas it exponentially decayed over time in bicontinuous phase structures. These results suggest that light-tunable microstructures enable the relaxation of the reaction-driven nonuniformity in solvent concentration distributions. Note de contenu : - Materials

In this sense, polyurethanes, which exhibit tunable chemical structures by selecting suitable precursors, can fit specific requirements, and the developments of green strategies make them important candidates for leather industry. This mini review briefly outlines the recent development of conventional (petrol-based) and sustainable polyurethanes in the leather industry, including their design and properties, in applications such as synthetic leather and surface-finishing (coatings/binders). Finally, outlooks of the future tendency, including more environmental-friendly strategies, bio-sourced/recycled materials and development of high-value multifunctional leather materials, are also here proposed.

Sol-gel, ProcédéIndex. décimale : 667.9 Revêtements et enduits Résumé : The increase in energy production costs for fossil fuels has led to a search for an economically viable alternative energy source. One alternative energy source of particular interest is solar energy. A promising alternative to inorganic materials is organic semiconductor polymer solar cells due to their advantages of being cheaper, light weight, flexible and made into large areas by roll-to-roll processing. However, the conventional architecture that is typically used for fabricating solar cells requires high vacuum to deposit the top metal electrode which is not suitable for roll-to-rolI processing. Anti-reflective coatings (ARCs) have evolved into highly effective reflectance and glare reducing components for various optical and opto-electrical equipments. Extensive research in optical and biological reflectance min im ization as wel I as the emergence of nanotechnology over the years has contributed to the enhancement of ARCs in a major way. In this review the prime objective is to give a comprehensive idea of the ARCs right from their inception, as they were originally conceptualized by the pioneers and lay down the basic concepts and strategies adopted to minimize reflectance. Antireflective coatings for solar cover glasses and photocatalytic coatings for self-cleaning glasses are two types of nano-functionalized thin films, which are extensively investigated at present.

SynergieIndex. décimale : 667.9 Revêtements et enduits Résumé : The current review explicitly describes the phosphorus-based flame-retardant (FR) coating materials derived from the bio-resources. It segregates the coatings according to their polymeric backbone type and correlates their structure with the end-application properties. The review will provide a readership to understand different chemistries of FR systems and implement similar in developing the bio-based FR systems for coatings. Furthermore, the review targets to brief the various mechanisms of phosphorus-based FR coating systems depending upon the resin type, such as epoxy, phenolic, polyurethane. The synergistic effects of phosphorus and other FR moieties are also discussed, along with their synthesis chemistries and the structural impact on the properties.

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : As the lightest structural metal and having a natural ionic presence with compatible biological systems, magnesium (Mg) has been emphasized in vehicle fuel economy for the automobile industry and is appropriate for biodegradable implants. However, the reactive nature of Mg makes it susceptible to corrosion. The electrochemical instability of Mg is due to long-term hydrogen gas evolution, microgalvanic reaction between the matrix and second phase, presence of impurities, and formation of non-protective corrosion product. Many studies have been done to protect Mg and its alloys from corrosion, and one way to prevent direct contact between magnesium substrate and corrosive medium is by applying a stable coating. Protective coating with self-healing properties has become an efficient technique to improve the corrosion resistance of Mg alloys. A self-healing coating can contain released ion exchange of corrosion inhibitors that could improve the coating stability significantly, while coating with embedded nanocontainers is able to autonomously self-heal via stimulus controlled-release upon crack and damages. In this review, recent studies on functional coating with self-healing ability including layered double hydroxides, cerium conversion coating, plasma electrolytic oxidation, graphene oxide coating, and smart self-healing coating are highlighted in the first section. The nanocontainers containing inhibitor coating and self-healing coating with superhydrophobic and biocompatibility function are reviewed afterward.
