Nano WO3 may be applied for producing an environmentally friendly nano transparent heat insulation coating. This new type of transparent thermal insulation coating is a recently developed glass energy-saving coating that can shield infrared light and ultraviolet light while maintaining high visible light transmittance.

As we all know, energy conservation is a new theme in today's society. Building energy consumption accounts for a relatively high proportion of total social energy consumption. It is reported that China's new construction area is nearly 4.5 billion square meters per year, of which more than 99% are buildings of high energy consumption. So, it is extremely urgent to realize the goal of environmental protection and energy conservation of buildings. Doors and windows, especially glass doors and windows, are the weakest part of building energy loss, accounting for about 30% of the building area, while energy consumption accounts for 2/3 of the total energy consumption, which is the main reason for the energy consumption of building heating and cooling. In order to save energy, researchers have carried out extensive exploration and research. They have developed low-emission coated glass, solar-controlled coated glass, glass film, heat-absorbing glass, insulating glass, vacuum glass and other energy-saving glass products, but these products often have low transmittance in visible light band. The processing of these materials is complicated, and the price is expensive, which limits their promotion. While the tungsten oxide transparent heat-insulating coating has the advantages of environmental friendliness, good heat insulation effect and simple preparation process so that it is relatively close to people. In a word, it provides a new direction for the problem of glass heat insulation, and therefore it has a good application prospect in the field of architectural glass.
