Nano particle size tungsten trioxide is a kind of infrared thermal insulation nano material. Such material that can block most of the near-infrared rays (the main source of heat) in sunlight, which mainly reflects the photochromic properties of tungsten trioxide. That is to say, the heat insulating material made of tungsten trioxide nanopowder may have a good thermal insulation effect, and its discoloration performance may change with the sun.
Tungsten trioxide also has electrochromic properties, and therefore it is widely used in a variety of vehicles. Thanks to the popularity of vehicles, tungsten trioxide electrochromic glass has potential applications in ordinary private cars, various buses, subways, and even high-speed trains. Electrochromism is the phenomenon displayed by some materials of reversibly changing color stimulated by redox reactions. Various types of materials and structures can be used to construct electrochromic devices. Electrochromic displays are based on any material that changes color depending on the applied potential. And tungsten trioxide is one of such electrochromic materials.
