Yellow tungsten oxide powder, which can be prepared by a sol-gel method or a magnetron sputtering method, can be used for studying and producing a large area electrochromic device. And experts said that the WO3 electrochromic film prepared by the sol-gel method has a faster response speed than the physical method such as the magnetron sputtering method. Besides, it is easy to prepare an electrochromic device of large area.

As you may have known, inorganic-organic nanocomposites, which are multi-dingal new materials that combine the excellent properties of inorganic materials, organic materials and nanomaterials, are emerging as a new and vital research field, attracting many researchers. Inorganic-organic nanocomposites have good mechanical, optical, electrical and magnetic dingal properties and have broad application prospects in many fields. In this regard, some experts said that PEO can accelerate the ion and electron conductivity. After doping a certain amount of PEO in the WO3 sol, it is expected to improve the response speed and discoloration effect of the tungsten trioxide film.
