Tungsten trioxide nanoparticles may be used for producing an energy efficient glass, which is an electrochromic glass to play the role of heat insulation and heat preservation. Experts introduced that the raw material WO3 nano powder is the most widely used electrochromic material currently. And related research on tungsten trioxide mainly includes the mechanism of electrochromism, various physical/chemical deposition methods for film preparation, the relationship between properties and film composition, structure, density and surface/interface morphology, as well as the design and preparation of various electrochromic devices.

So, what are the advantages of WO3 smart glass?
1.0 Fire protection. With characteristics of resisting high temperature, it can prevent the damage caused by the hot brittleness of the glass under high temperature conditions, and delaying the softening time of the glass under high temperature conditions.
2.0 Environmental protection. The material is environmentally friendly so that it will not pollute the environment, and will not cause harm to the human body.
3.0 Sun protection. The UV shielding rate exceeds 99%, protecting the skin from direct sunlight.
4.0 Anti-theft. More than 500% hardness of common glass and 30, 000Psi high tensile strength, 160% high elongation, so gangsters are not easy to break, delaying the invasion time.
5.0 High thermal insulation and heat preservation. It can meet the basic needs of most people.
