WO3 based electrochromic film has excellent intelligent dimming ding. As you may know, in order to improve the coloring efficiency of traditional tungsten trioxide electrochromic materials and devices, it is often necessary to implant ions and electrons deep into the tungsten trioxide material. Besides, due to the poor conductivity of tungsten trioxide itself, its electrochromic response times tend to be longer.

Therefore, in order to shorten the response time of tungsten trioxide based electrochromic materials, experts often use organic/inorganic composite methods to make high-performance organic/inorganic composite electrochromic material by using the extremely high specific surface area of tungsten trioxide nanostructures and good cycle stability, combined with the better electron transport speed of organic electrochromic materials. Among them, the conductive high molecular polymer represented by polyaniline, polythiophene and polypyrrole has a fast electrochromic response speed and good molecular tailorability. Therefore, many experts are working to combine tungsten trioxide with a conductive polymer with an electrochromic performance to obtain an electrochromic film with a fast response speed and good cycle stability.
