Tungsten Oxide Applied for Liquid Electrochromic Device

Tungsten oxide for production of liquid electrochromic device is an inorganic electrochromic material. In fact, there is another type of electrochromic material, that is, an organic electrochromic material. So, do you know the difference between inorganic electrochromic materials and organic electrochromic materials?

This can be seen from the comparison of the characteristics of inorganic electrochromic materials and organic electrochromic materials. Although organic electrochromic materials have many advantages over inorganic electrochromic materials, such as lower cost, better optical properties, faster color change and better cycle reversibility. Also, it is generally multi-color and easy to optimize performance by molecular design. However, organic electrochromic materials also have some disadvantages, such as poor chemical stability, poor radiation resistance, and poor adhesion to substrate inorganic materials. These shortcomings are very fatal, which is directly related to the problems of the use of the prepared electrochromic device and the length of service life. While inorganic electrochromic materials do not have the above disadvantages, so it is more and more popular.
