Cs0.32WO3 nanoparticles have high concentration of free carriers, high visible light transmission and high near-infrared light shielding performance, so they may be used to produce good near-infrared shielding material for applying in car heat insulating window glass. In addition, cesium tungsten bronze nano functional particles also have a very broad application prospect in the construction industry. Such new heat-insulating particles are often prepared into transparent heat insulating materials, such as, heat insulating film, heat insulating dispersion, and heat insulating coating, etc.

Cs0.32WO3 nanoparticles may be used to prepare an energy-saving window heat insulation film with the advantages of environmental protection. The prepared thin film is a high-tech product that allows the glass to maintain high light transmission while being highly effective, heat-insulating, UV-resistant and radiation-proof. So, such heat insulating film may be applied to architectural glass to obtain insulated architectural glass.

Cs0.32WO3 nanoparticles may be used for the preparation of thermal insulation film, and thus be used in automotive glass to obtain thermal insulating glass. It is well known that some automotive films are able to block UV rays as a large amount of UV blockers are added during the manufacturing process. The UV blocker referred to herein is a material that specifically blocks the passage of ultraviolet wavelengths.

Some experts use Cs0.32WO3 nanoparticles (cesium tungsten bronze nanoparticles) as functional particles and epoxy resin as film-forming material to prepare transparent heat insulation coating. The visible light transmittance of the obtained thermal insulation coating is above 80%. And the acid and alkali resistance of such coating are in line with the construction industry standards.
