Mo-doping tungsten oxide film can be used as an electrochromic layer and assembled into an electrochromic device by thermocompression film method. While how to assemble electrochromic devices by hot pressing film method?

As an electrochromic material, WOx film can be steady-state WO3 film or metastable tungsten oxide, experts said. Well, as you may have known, there are many types of electrochromic materials, including inorganic electrochromic materials, and organic electrochromic materials, etc. The WOx film is an inorganic electrochromic film.

Porous tungsten trioxide electrochromic film can be prepared by sol-impregnation pulling method. In this regard, experts said that preparing tungsten oxide film by this method has the advantages of simple equipment and low film forming cost. Also, you can prepare an electrochromic thin film of large glass area, which is now the important research direction for smart buildings.

Porous tungsten oxide film is a transparent heat insulating film with superior electrochromic properties than the conventional dense tungsten oxide film. And its possibility of being applied to electrochromic glass is often studied. While you should prepare the object of study firstly. So, how to prepare such a tungsten trioxide heat-insulating film?
