Nanometer yellow tungsten oxide is a new type of infrared thermal insulation nano material that may be used in architectural glass and automotive glass. Nano grain size yellow tungsten oxide is also an electrochromic material. As you may have known, electrochromic materials are widely studied as a category of the most promising smart materials available. Among them, inorganic metal oxides are the most studied category, especially yellow tungsten oxide (tungsten trioxide) and NiOx. Nowadays, many materials prepared by using electrochromic materials have been applied to the market.
Electrochromic materials have bistable properties. Electrochromic displays made of electrochromic materials do not require a backlight. Also, it will not consume electricity as long as the display content does not change. It means that this type of product saves energy. What is more, compared with other displays, electrochromic displays have the advantages of no blind angles and high contrast. However, what should be noted is that there are still some problems in the application of electrochromic materials. And such electrochromic material requires further improvement.
