Tungsten trioxide, as an n-type semiconductor material, is often doped with Cs+. And then the doped tungsten trioxide material is prepared into the dispersion solution for adding to the preparation of heat insulation coating. Finally, the smart coating is applied to the office building with glass curtain wall to play the role of high infrared shielding and good transmittance in the visible light region. Such coating solves the contradiction of "high transparency and high heat insulation" of the glass curtain walls of the office building. So, tungsten trioxide has extremely high application value.

With the rapid economic growth of our country, energy conservation and environmental protection have been paid more and more attention. For large-scale windows and transparent ceilings of buildings where used a lot of glasses, the heat radiation of sunlight will increase the use of air conditioners and waste energy. Therefore, develop a material with good transparency and thermal insulation properties not only has important theoretical significance for solving the problem of glass thermal insulation, but also has a broad market prospect. In this regard, experts said that the transparent heat insulation coating made of tungsten trioxide is a new smart material developed in this case.
