WO3 Electrochromic Film Applied for Electrochromic Window

WO3 electrochromic film, as a new energy-saving material, can be used to assemble an electrochromic window. Experts believe that the application of tungsten oxide electrochromic windows in the field of building energy conservation is very broad, and thus tungsten oxide products including tungsten oxide powder, tungsten oxide film and tungsten oxide electrochromic device have received more attention.

In this regard, experts say that if we can break through many key technologies in the preparation and application of electrochromic materials, and develop high-performance, low-cost and practical electrochromic materials, it is expected to solve the bottleneck problem of the existing electrochromic thin film materials in practical applications. In addition, experts also introduced that in addition to electrochromic materials, electrolytes are another key to the successful commercial application of electrochromic devices. The most used liquid electrolyte in electrochromic devices is prone to leakage during use, which greatly reduces the performance of the device and shortens the service life of the device. The solid electrolyte has low ionic conductivity, so its electrochromic performance is poor during use. In recent years, research on polymer/salt systems has gradually increased, which has led to an increasing focus on polymer gel electrolytes, and related research is still a hot topic. The ionic conductivity, thermal stability and electrochemical stability of polymer electrolytes are a major problem. Successfully solving these problems can prepare more stable electrochromic devices with better electrochromic properties, and therefore greater progress can be made in the application of smart windows.
