Nano tungsten oxide may be used to prepare a transparent heat-insulating energy-saving film, which also has the advantage of a decorative film. Nowadays, the decorative film is applied in more and more places. It not only achieves the effect of beautifying the building, but meets the increasing privacy requirements of modern people.

However, as the common decorative film does not have heat insulation property, the experts have developed a tungsten trioxide energy-saving decorative film, which can simultaneously exert the dings of the heat insulating film and the decorative film. Such new environmentally friendly smart film can be used on the exterior and interior of the building, including glass curtain walls, glass doors, glass windows, and sun room glass. And the obtained glass will have the characteristics of high thermal insulation, high heat preservation, high hardness, high strength, high adhesiveness, UV resistance, heat resistance, water resistance, fireproofing and long service life.
