Using IR-reflective pigments suspended in exterior wood coatings can lower the surface heating of dark-coloured coatings. The performance and weather resistance of such IR-reflective coatings are comparable to that of commercial coatings with conventional pigmentation while also reducing the risk of heat-related damage to wood and coatings.

TitanatesLes titanates sont des composés inorganiques dont la composition combine un oxyde de titane à un autre oxyde. Le terme est parfois utilisé plus généralement pour tout composé comportant un anion du titane, par exemple [TiCl6]2− et [Ti(CO)7]2−.
On connaît un grand nombre de titanates, dont plusieurs ont une importance économique. Ce sont typiquement des matériaux blancs, diamagnétiques, à haut point de fusion et insolubles dans l'eau, que l'on prépare généralement à haute température (par exemple en utilisant un four tubulaire (en)) à partir de dioxyde de titane1.
Plusieurs titanates sont connus à l'état naturel, c'est-à -dire sous la forme de minéraux, dont les principaux sont l'ilménite FeTiO3 et la pérovskite CaTiO3.
Dans la quasi-totalité des cas, le titane a dans les titanates une coordination octaédrique (coordinence 6). Dans les cristaux de titanates il n'y a pas toujours un oxoanion du titane bien identifié (comme [TiO3]2− ou [TiO4]4−) mais souvent un cation Ti4+ ou des situations intermédiaires. (Wikipedia)Index. décimale : 667.9 Revêtements et enduits Résumé : Layer-by-layer (LbL) films have been developed for multiple applications, including functional coatings with antimicrobial activity. In this work, we describe the development of LbL films based on polyaniline (PANI), titanate nanotubes (TiNTs-Na2Ti3O7), and cetyl trimethyl ammonium bromide (CTAB) for applications in antifungal coatings. The LbL films were characterized by spectroscopy in the UV–visible region, cyclic voltammetry, scanning electron microscopy, and atomic force microscopy. Among various films architectures tested, the PANI(TiNTs)/CTAB film was more promising for the suggested applications. This film showed excellent activity against Cryptococcus neoformans fungi, showing inhibition zones. The material developed in this work is a candidate for coating of air conditioning pipes, for instance, since besides the antifungal activity, it also adds the anticorrosive and air-purifying properties present in PANI and TiNTs.

Revêtements protecteursIndex. décimale : 667.9 Revêtements et enduits Résumé : Layered double hydroxides (LDHs) are an emerging technology that is used as a filler in coatings due to its structural and compositional flexibility. LDHs are layered compounds composed of positive metal hydroxides and negatively charged interlayer anions. We have discussed the structures and characteristics of LDHs in this review study, as well as many processes, such as the barrier mechanism, self-healing corrosion inhibitor method, and superhydrophobic mechanism, that demonstrate how LDHs operate in anticorrosion coatings. Additionally, how the use of LDH imparts flame-retardant qualities to the coatings is covered here, along with their respective processes. LDH coatings are suitable for packaging, biomedical, water treatment, and conductive applications alone or in combination with other materials.
