Yellow tungsten oxide is the most commonly used material for the preparation of an inorganic electrochromic film. And the obtained film can be used for producing an all-solid electrochromic glass, that is, the so-called smart glass, which is more and more widely applied in smart buildings to play the role of heat insulation in summer and heat preservation in winter. So, how to prepare WO3 electrochromic film?

Yellow tungsten oxide, or tungsten trioxide, may be prepared into an electrochromic film, and then be used to produce a smart glass - a new energy-saving material. Due to its excellent heat insulation and heat preservation performance, such material is more and more widely applied in building energy-saving renovation. Experts say that tungsten trioxide film is probably the most practical electrochromic material in many electrochromic materials.

Yellow tungsten oxide nanopowder may be used to produce an electrochromic glass, that is, a smart glass with excellent optical adjustment properties. In other words, such smart glass is mainly used to achieve the effects of thermal insulation and heat preservation with high transparency so that it is more and more widely applied in the heat insulating field of construction and automotive glass. for such electrochromic material, experts say that the following reversible reactions occur when the WO3 film is electrochromic:

Yellow tungsten oxide, or tungsten trioxide, has excellent optical adjusting properties and therefore it may be used to produce an all-solid-state electrochromic smart window. According to experts, WO3 electrochromic film is considered to be the most promising inorganic electrochromic material used in construction and automotive windows.
