It is reported that the tungsten trioxide energy-saving film can be prepared by the PS ball template method. Some experts have prepared macroporous WO3 array films on the surface of ITO glass by using the PS ball template method. According to the experts, the spectral modulation amplitude and discoloration speed of the prepared electrochromic thin film have been greatly improved. At the same time, the cycling performance of the macroporous WO3 array film has not been significantly reduced. That is to say, such a nanostructured WO3 thin film may be applied to glass windows and glass doors of buildings for saving energy and protecting environment. In addition, the experts also mentioned that porous WO3 films can provide more active interfaces for electrochemical reactions, shorten ion diffusion paths, and enhance electrode reaction kinetics.
