Nano cesium tungsten oxide powder may be applied for the preparation of thermal insulation film, which is an energy-saving and environmentally friendly heat insulating film. The obtained heat-insulating film has an excellent effect of preventing ultraviolet rays and infrared rays. And such thin film does not affect light transmission. At the same time, its thermal insulation performance is good, which makes the interior of the building or car space to which the thermal insulating film is applied comfortable and safe.
In other words, the heat-insulating film to which the cesium tungsten oxide nanoparticles are added has high heat insulation and high light transmittance. And it can also save construction refrigeration and heating costs. In addition, the new dingal film can also avoid the discomfort caused by glare lighting and exposure, increase the user's environmental comfort, and save the user's curtain cost. And such heat insulation film is available in different colors to enhance the aesthetics of the building.
