WO3, or tungsten trioxide, is an important raw material for the preparation of all-solid-state electrochromic smart window. Nowadays, the prepared smart window is widely used in construction or automobile to achieve the purpose of “warm in winter and cool in summer”. Also, such smart glass has the advantages of anti-UV, non-glare, safety and environmental protection.

Tungsten trioxide is an important raw material for the preparation of inorganic electrochromic film. The prepared electrochromic film is a good helper for achieving the function of heat insulation and heat preservation of architectural glass, automotive glass and even aircraft glass. So, do you know what is the electrochromic mechanism of a tungsten oxide film?

Tungsten trioxide can be prepared into an electrochromic film, and then be used to produce a new energy-saving window - an all-solid-state electrochromic smart window. The prepared smart window is a new type of heat insulation window with high thermal insulation performance and high heat preservation performance. So, how is this smart window made up? We can see from the structure of the electrochromic window.

Tungsten trioxide nanoparticles, as one of the most important raw materials applied in the preparation of smart window, have the characteristics of environmental protection and excellent optical properties. So, this new type of smart glass is increasingly used in the field of construction and auto. Therefore, not only the WO3 film, but also the Ti-doped tungsten trioxide electrochromic film has received much attention.
