WO3-TiO2 electrochromic material can be an electrochromic device that is assembled with a WO3 electrochromic layer and a TiO2 ion storage layer. The electrochromic material is a new type of dingal material with the characteristics of good chemical stability, simple preparation process, strong radiation resistance and strong adhesion to the substrate. And it is easy to achieve full curing. So, such a smart material is widely used in information, electronics, energy, construction (smart windows) and defense.

There are many preparation methods of WO3-TiO2 electrochromic material. The preparation methods including electrochemical deposition method, vacuum evaporation method, sputtering method, chemical vapor deposition method, ion plating technology and sol-gel method are commonly used at home and abroad. Among them, the electrochemical deposition method refers to a preparation method that a desired film can be formed on the surface of the working electrode by applying an electric current to an electrolyte. Compared with other methods, the electrochemical deposition method has the advantages of simple equipment, strong controllability and uniform coating film. Also, such a method can be used to prepare composite film.
