WO3 Electrochromic Film

WO3 electrochromic film is a new type of electrochromic material, which is more and more widely used in the production of smart glass. According to experts, the preparation method of tungsten trioxide film covers almost all the preparation technologies of the film electrode.

According to experts, the commonly used preparation methods for tungsten trioxide electrochromic films include hydrothermal/solvent thermal method, sol-gel method, electrochemical deposition method, sputtering method, anodizing method, inkjet printing film forming process and other physical and chemical methods.

Among them, hydrothermal/solvothermal method is the most widely studied preparation method of tungsten trioxide electrochromic thin film as it has the advantages of good film formation and controllable nanostructure. Hydrothermal and solvothermal reactions can synthesize materials with various special nanostructures, which have the advantages of low temperature growth, controllable size and low process cost. In addition, the hydrothermal method differs from the solvothermal method in the reaction solvent.
