WO3 electrochromic film for heat insulating window glass has the highest coloring efficiency and excellent electrochromic properties, and thus it has been studied deeply, applied widely and developed extensively. For example, some experts have studied the relationship between the electrochromic coloring efficiency and the density of a tungsten trioxide film.

WO3 electrochromic film for heat insulating glass can be prepared by a sol-gel method. For example, some experts have adopted sol-gel method to prepare tungsten trioxide electrochromic thin films, and designed the experiments by orthogonal design.

WO3 electrochromic film for thermal insulating glass can be prepared by electrophoretic deposition. Experts say that the obtained tungsten oxide film has extremely high response speed and large coloring efficiency. And it is low in cost. It is reported that many experts have adopted this method to conduct research on tungsten trioxide electrochromic thin film.

Building energy efficiency is an important theme in today's society, which has received wide attention from people from all walks of life. Also. It is closely related to our lives. While do you know how to prepare the WO3 electrochromic film that can exert energy-saving effects to reduce the burden of the building?

Mo-doped WO3 electrochromic film can be prepared by spray pyrolysis. Then, how to prepare Mo-doped tungsten oxide electrochromic film by spray pyrolysis?

Mo-doping WO3 electrochromic film can be prepared combining magnetron sputtering method and spraying method. So, do you know the specific steps of preparing Mo-doped tungsten oxide electrochromic film by magnetron sputtering and spray coating?

Mo doping tungsten oxide electrochromic film can be prepared by a spray coating method. First, prepare a Mo-doped tungsten oxide nanosol, followed by preparation of a Mo-doped tungsten oxide electrochromic film.

Mo-doped tungsten oxide electrochromic film is a type of widely studied and applied electrochromic layer material, which is extremely important for producing smart windows as the color change of smart window is achieved by the change in the valence state of the electrochromic material. For example, when a negative voltage is applied to the electrochromic layer (WO3 film), the cations (H+, Li+) migrate into WO3 to change the valence state of the W atom, showing a blue color.

WO3 powder can be prepared into an electrochromic film and then be used to assemble a large area electrochromic glass. As you may have known, the reason why the color of tungsten oxide electrochromic film undergoes a reversible transition in a specific wavelength range of light is that WO3 undergoes a redox reaction under the stimulus of applying a lower voltage to it. In fact, the color change of tungsten oxide electrochromic film is mainly due to the fact that it produces a new absorption band in the spectral region.

Tungsten oxide powder can be prepared into a tungsten oxide film with high electronic conductivity, ionic conductivity, large light modulation range, high coloring efficiency and good cycle stability, and then be used as an electrochromic layer for assembling large area electrochromic glass. And these smart glasses may be applied in the buildings and automobiles for heat insulation performance.
