Tungsten oxide nanoparticles can be used to prepare a variety of transparent thermal insulation materials, such as thermal insulation films, thermal insulation dispersions and thermal insulation coatings. Regardless of the type of heat insulation material, transparent heat insulation glass can be obtained by applying these materials to building glass. And the obtained heat-insulating glass can absorb near-infrared rays and shield ultraviolet rays. Also, such smart glass is environmentally friendly and safe. In means that the glass will not pollute the environment without toxic substances.

As you may have known, at present, the main applications of transparent thermal insulation materials are heat-reflecting glass and low-emissivity glass. The former achieves thermal insulating effect by high-reflection of near-infrared, and the latter achieves heat-insulating effect by high-reflecting indoor heat in the room. However, the preparation process of the two types of glass is complicated and expensive, and the heat-reflecting glass has defects such as "light pollution". While tungsten trioxide heat insulating glass does not have the above problems. Such glass is a new type of smart glass, so it is more and more popular among people.
