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.

W18O49 nanorod can be used to prepare an electrochromic thin film that can achieve thermal insulating and anti-UV performance. Nowadays, such smart film has been applied more and more to large-area glass such as glass curtain wall and floor-to-ceiling windows to achieve the goal of “warm winter and cool summer”. So, how to prepare tungsten oxide nanorod powder?

Tungsten oxide nanorod can be used to prepare an electrochromic thin film, which can be applied to architectural glass or automotive glass to provide advantages such as heat insulation, energy conservation, UV resistance and electricity reduction.

Blue tungsten oxide can be used to prepare an inorganic electrochromic film, which is then applied to architectural glass to obtain smart glass, for shielding infrared rays that will heat the building without affecting indoor lighting.
