Tungsten oxide, or WO3-X, can be used to prepare an electrochromic thin film, which is an environmentally friendly thermal insulation film. For the raw material tungsten oxide nano powder, it has been found that the surface morphology and crystal structure of the tungsten oxide nano particles largely determine its electrochromic properties. And some experts have also studied the difference in electrochromic properties between crystalline tungsten oxide and amorphous tungsten oxide.
