Electrochromic Film: Tungsten Trioxide Film

Tungsten trioxide film is an important electrochromic film. In recent years, WO3 electrochromic thin film has been well received by scientists in the field of energy-saving building materials, as the electrochromic glass assembled using WO3 film as an electrochromic layer is an environmentally-friendly energy-saving glass with remarkable heat insulation and heat preservation effect. Also, such glass can prevent glare and ultraviolet light. So, what method can WO3 film be prepared by?

Some experts have prepared tungsten trioxide electrochromic thin films by electrophoretic deposition method. The experts used stainless steel plates as anodes, treated ITO glass as cathodes, applied a certain voltage, and performed sol-electrophoretic deposition in a self-made electrophoresis device. After a period of time, the ITO glass was taken out, allowed to stand for a while, and dried under an infrared lamp. Then, the heat treatment is carried out at different temperatures, and the WO3 film can be obtained after natural cooling.
