Cs doped tungsten oxide nanoparticles, namely cesium tungsten bronze nanoparticles with the chemical formula CsxWO3, are often used to prepare infrared thermal insulation nano material such as thermal insulation film. With the popularization of such a transparent thermal insulation film in the field of buildings and autos, more and more scholars have begun to pay attention to the preparation of the infrared thermal insulation nano material - CsxWO3 film.

Preparation of Thermal Insulation Film Containing Cs Doped Tungsten Oxide Nanoparticles
According to experts, after the CsxWO3 powder was thoroughly ground, it was ultrasonically dispersed in a citric acid solution for 1 h, then added to a 0.1 g/mL polyvinyl alcohol (PVA) solution, stirred in a water bath at 80 °C for 30 min, and aged for 1 day to obtain the latex, and finally a CsxWO3 film is prepared on a glass slide by sol-gel dip-coating method.
