Violet Tungsten Oxide Nanopowder Applied for Transparent Heat Insulation Glass

Violet tungsten oxide nanopowder is a nano functional material, more specifically,  a transparent heat insulating filler, which may be used to prepare transparent heat-insulating film or transparent heat-insulating coating, and then be applied to architectural glass to obtain transparent heat insulation glass. Experts said that the dispersion stability of nano functional material in coatings has a significant impact on the thermal properties and optical properties of transparent thermal-insulation coatings.

Experts explained that this is because the nano tungsten oxide material has a small particle size and a very high surface energy, so it is easy to form agglomerates. Therefore, only by uniformly dispersing the tungsten oxide nanoparticles in the coating can the surface and interface effects, small size effects and macroscopic quantum effects of the nanoparticles be maintained. Experts also introduced other functional materials for preparing coatings, except tungsten oxide nanopowder. There are common heat-insulating fillers. They are transparent conductive oxides such as nano ATO, ITO and rutile TiO2.
