Nano tungsten trioxide is an important inorganic functional nano material for preparing bathroom heat insulating glass coating. In this regard, some experts started with the dispersion of WO3 nanopowder and tin antimony oxide (ATO) nanopowder, and prepared three systems of transparent heat-insulating coatings. They are nano ATO/two-component water-based polyurethane coatings, nano WO3/two-component water-based polyurethane coatings, and ATO-WO3/bi-component water-based polyurethane coatings, respectively.

WO3 electrochromic thin film is a new type of environmentally friendly smart material that is expected to be popularized and applied on energy-saving window. With the promotion of tungsten oxide electrochromic films in the field of building energy conservation, more and more experts and scholars have begun to pay attention to the preparation of such smart films. The following is a method for preparing WO3 electrochromic thin film:

WO3 electrochromic thin film for energy-efficient window can be prepared by traditional preparation methods, such as hydrothermal method, sol-gel method, evaporation method, sputtering method, electrodeposition method, and pulsed laser deposition method. Also, the WO3 film can be synthesized by a new method combining a liquid laser ablation technique and an electrophoretic deposition method.

The tungsten trioxide nano-film is attracting much attention as it can be used to assemble an electrochromic device for applying to energy saving reconstruction of building. Well, do you know how to prepare such a WO3 nano film? Some experts have proposed a method for preparing highly ordered tungsten trioxide nano-film.
