Nano tungsten oxide may be applied for preparing thermal insulation film. This kind of heat insulation film is a type of excellent building energy-saving material, which can be applied in various architectural glasses.
Due to environmental protection, energy conservation and rising energy prices, transparent heat insulation film of tungsten oxide has received more and more attention at home and abroad. Therefore, the problem of energy consumption control in building heating and cooling has also arisen. Among them, the energy loss caused by the loss of window accounts for a considerable proportion. According to statistics, China's building energy consumption accounts for about 28% of total social energy consumption, and it is expected that by 2030, this figure will rise to 40%. It means that the energy loss in building will exceed industrial energy consumption. In fact, only the energy loss in window accounted for 30% to 50% of the total building energy loss. This phenomenon can be attributed in part to the lag in the development and application of building energy-saving materials. Therefore, the development of thermal insulation films such as tungsten oxide films has become more and more important.
