The nano cesium tungsten bronze powder produced by our company is an inorganic nano material with good near-infrared absorption, with uniform particles and good dispersion. It has good absorption in the near-infrared region (wavelength 800-1200nm) and high transmittance in the visible light region. The visible light transmittance of the thin film prepared by using nano cesium tungsten bronze powder is more than 70%. Used together with our nano tin oxide antimony, it can be made into a transparent thermal insulation coating with infrared blocking.
Cesium Tungsten Bronze (Cs0.33WO3) is a non-stoichiometric functional compound with a special structure of oxygen octahedron, with low resistivity and low temperature superconductivity. In recent years, it has been discovered that CsxWO3 film has good near-infrared shielding performance, which is expected to replace the existing ITO conductive glass. As a window material, it can be used as a good near-infrared heat insulation material and has good applications in the automotive and construction fields. prospect.

Modern buildings use a large number of thin and transparent external materials such as glass and plastic. While improving indoor lighting, these materials cause sunlight to enter the room and cause the indoor temperature to rise. In summer, in order to balance the increase in indoor temperature caused by sunlight, people generally use air conditioners to cool down. This is also the main reason for power cuts in some areas of my country in summer. The current effective method is to add nanoparticles with the ability to absorb infrared light, such as antimony-doped tin oxide (ATO), indium tin oxide (ITO), lanthanum hexaboride and cesium tungsten bronze nanoparticles into the resin to make Transparent heat-insulating paint is directly coated on glass or sunshade cloth, or first coated on PET (polyester) film, and then the PET film is pasted on the glass (such as car film), or made into a plastic sheet, such as PVB ( Polyvinyl butyral), EVA (ethylene-vinyl acetate copolymer) plastics, and then these plastic sheets and tempered glass compound, also play a role in blocking infrared, so as to achieve a transparent heat insulation effect.
