Nano tungsten oxide may be applied for producing thermal insulation masterbatch, which reflects its photochromic properties. Tungsten oxide also has electrochromic properties so that it can be used for heat insulation in large-area building curtain walls, such as, architectural glass. Among them, the two most important performance indicators of solid inorganic electrochromic materials in large-area building curtain wall applications are — response time and cycle life. Then, there is something about the research progress of the electrochromic properties of tungsten…
