Cesium tungsten oxide is a new material that has been discovered in recent years for the preparation of heat insulation coating. This kind of coating has outstanding near-infrared shielding effect and visible light transmission rate. Therefore, it has broad application prospects in building heat insulation, automotive heat-insulating film and greenhouses. At present, some famous paint companies in Japan, Germany, and the United States are vigorously developing the transparent heat insulation coating of cesium tungsten oxide.
The window heat-insulating film made of this type of heat insulation coating may reduce excess heat gain on hot sunny days, and therefore, reduces electric charge on air-conditioning.
The cesium tungsten oxide nanopowder is a kind of inorganic nanopowder that has the best absorption performance on near-infrared rays. It not only has strong shielding characteristics in the near-infrared region (wavelength 800-1100nm) and ultraviolet region (wavelength 200-380nm), but also has high transmittance in the visible light region (wavelength of 380-780nm).
