Tungsten oxide smart glass not only can adjust the transmittance in the visible light region, but also has a shielding effect on the infrared light in the colored state. This is because the electrochromic glass of tungsten oxide nano particles can actively block the heat loss caused by the indoor and outdoor temperature difference and reduce the energy consumption caused by building cooling and heating.

Mo doped WO3 electrochromic film has much similar electrochromic properties as the WO3 electrochromic film. As you may have known, tungsten trioxide electrochromic film has been more and more widely used in building glass. Thus, the Mo-doped WO3 electrochromic film has also become a hot spot of current research.

Ti doped WO3 electrochromic film can be prepared by spray pyrolysis process, which improves the cycle stability and charge storage capacity.

WO3 based electrochromic film has excellent intelligent dimming function. As you may know, in order to improve the coloring efficiency of traditional tungsten trioxide electrochromic materials and devices, it is often necessary to implant ions and electrons deep into the tungsten trioxide material. Besides, due to the poor conductivity of tungsten trioxide itself, its electrochromic response times tend to be longer.

Inverse opal structure WO3 electrochromic film can be prepared by a sol gel method. Since the obtained tungsten trioxide electrochromic film has a large porous structure, it has a relatively fast response time.

Porous crystalline WO3 electrochromic film can be prepared by electrodeposition method. So how to prepare tungsten trioxide electrochromic film by electrochemical deposition process?

WO3 coated glass can be prepared by sputtering process. At present, some foreign companies have mass-produced tungsten trioxide coated glass by sputtering method. According to experts, such method has the advantages of uniform film thickness, strong adhesion between the film and the substrate, so it is suitable for mass production.

Porous WO3 electrochromic film can be prepared by anodic oxidation process. Experts say that the tungsten trioxide electrochromic film prepared by anodic oxidation method tends to have a loose porous structure, which is more conducive to ion insertion and extraction, so that it has better electrochromic properties.

Tungsten trioxide based inorganic electrochromic film can be prepared by an inkjet printing film forming process. As you may have known, with the rapid development of electronic devices, printing electronic technology has increasingly become the focus of academic field and industrial circles.

WO3 electrochromic film is a new type of electrochromic material, which is more and more widely used in the production of smart glass. According to experts, the preparation method of tungsten trioxide film covers almost all the preparation technologies of the film electrode.
