“…Titanium oxide nanocrystals were synthesized by a modified synthesis route involving the reaction of titanium chloride with poly(ether glycol) of high molecular weight (i.e., with poly(1,4-butanediol)). This synthesis is based on the formation of partially hydrolyzed titanium alkoxide and the elimination of organic halite and HCl via a subsequent polycondensation reaction, as illustrated in Supporting Information Scheme S1. , This reaction, which is performed at 120 °C, causes a stable colloidal dispersion of the TiO 2 nanocrystals in the polymer solvent. Apparently, there is no clear evidence of nanocrystal formation because the resulting products have transparent features in visible light.…”

This article describes a different approach to the colloidal synthesis of TiO(2) nanocrystals using a polymer melt as a solvent. This approach allowed us to obtain a colloidal dispersion with a high degree of stability in a polymeric solvent, resulting in a transparent colloid. Using this method, it was possible to obtain the TiO(2) nanocrystal with Brønsted acid sites and polymer chains chemically anchored on the nanocrystal surface. The acid surface of those nanocrystals has the chemical property to react in the presence of amine organic compounds and to maintain the colloidal stability. In this way, TiO(2) nanocrystals were combined with a molecular probe containing amine functional groups such as polyaniline. Through the combination of the molecular probe and inorganic nanocrystals, we obtained a hybrid material with interesting chemical, optical, and electronic behavior, making it a promising material for photovoltaic, photochromic, and sensor devices.

Electrical insulating enamels are usually made of thermosetting resins diluted in suitable solvents, which can be enameled on magnetic wires. PEI‐based enamel is one of the most important insulating enamels in electrical engineering. The characteristics of various PEI based wires are quite different depending on the final use. Using special additives, it is possible to produce optimized PEI versions with improved characteristics. Special applications are possible by introducing pigments or conductive materials in the formulation. Thermoplastic PEI are also obtainable. This review gives an overview of the fascinating world of PEI, from discovery up to the latest developments.magnified image

The scientific and industrial history of polyurethane wire enamels during the previous six decades is reviewed. Their main use is as coatings for wires in miniature electrical devices and in electronics, where fast solderability at low temperatures is crucial. Market trends for polyurethane enamels are discussed, and an outlook is provided as to how future developments might influence the industrial use of polyurethane wire enamels.magnified image
