Tungsten oxide has the advantages of high transparency, high thermal insulation, and NIR-shielding performance so that it can be applied for window heat insulation film.
Why window heat insulation film is necessary for building windows?
60% of the solar thermal energy enters the room through the window, while the general glass can only block 7% of the solar thermal energy, which makes the indoor temperature in the summer high within a certain temperature range, resulting in the frequent and lasting use of air conditioning, and thus the proportion of air conditioning in electricity charges will be greatly increased.
Moreover, in summer, air-conditioning consumes a lot of electricity, which is not environmentally friendly. Therefore, the theme of environmental protection such as energy conservation and reduction of carbon dioxide emissions has promoted the development of building energy efficiency. Therefore, nano grain size tungsten oxide, as a new infrared ray shielding material of great significance, has become a key object in study.
