Tungsten oxide film can be used to assemble a smart glass and then be applied to buildings to obtain smart windows with performance of energy conservation and environmental protection. This is because the tungsten oxide electrochromic glass can change the visible light and the infrared light transmittance to adjust the indoor temperature and realize the dynamic adjustment of the indoor brightness, thereby significantly reducing the energy consumption of the building. In a word, tungsten oxide smart window is a heat insulating glass.

In addition, experts say that in electrochromic devices, the electrolyte mainly provides conductive particles for the electrodes, so that it is an indispensable component. Experts have focused on gel-state electrolytes by adding polymers, ionic liquids, and inorganic nanoparticles to liquid electrolytes to prepare gel-state electrolytes suitable for electrochromic devices. Moreover, the electrochromic properties were studied by preparing an electrochromic device with a tungsten oxide electrochromic thin film.
