Nano tungsten oxide, which may be applied for preparing ceramic microsphere, is an excellent electrochromic material with good stability, mainly showing in the following two features: 1. It has better structural stability during color reversible change process, which requires electrochromic materials to be less prone to irreversible structural damage during ion insertion and extraction, thus showing good reversibility of redox and color change, and long cycle life. 2. With high chemical stability, good weather resistance and corrosion resistance, it can…

Nano tungsten oxide may be used in heat insulating window glass, which is mainly to shield the ultraviolet (UV) and infrared rays, thereby reducing the temperature inside the car and improving the comfort of human body. Tungsten oxide can also be used on electrochromic devices with excellent electrochromic properties. And therefore, such electrochromic devices will have shorter color change response time, i.e., higher color conversion rate. This requires that the entire color change reaction have higher reaction rate under the…
