Nano Cs doped tungsten oxide, or nano grain size cesium tungsten bronze, or Cs0.33WO3 nano particles, may be applied for preparing infrared thermal insulation nano material such as transparent thermal insulation coating, which can be applied to architectural glass. As you may have known, the properties of transparent heat insulation coating made of different film-forming materials has both same and different points, which will affect the visible light transmittance and near-infrared shielding of the coating.

In this regard, some experts have studied the effects of different film-forming substances on the performance of transparent thermal insulation coatings. They prepared Cs0.33WO3 coatings using with polyvinyl alcohol (PVA), polyvinyl butyral (PVB) and polyvinylpyrrolidone (PVP) as a film-forming material respectively. Studies have shown that both PVA/Cs0.33WO3 coating and PVP/Cs0.33WO3 coating have good visible light transmittance and near-infrared shielding ratio, and PVP/Cs0.33WO3 coating has the best adhesion strength. In a word, heat insulation coating of nano cesium tungsten bronze has the above-mentioned advantages. And the film-forming substance also has an influence on the coating to some extent.
