Nano cesium tungsten bronze for balcony thermal insulating film can be prepared by the low temperature hydrothermal reaction. For example, the experts synthesized cesium tungsten bronze (CsxWO3) powder by such a method using sodium tungstate and cesium carbonate as raw materials, with citric acid as the reducing agent.

Cesium tungsten bronze nanopowder is mainly applied for preparing study thermal insulating film. To improve the near-infrared shielding performance and transparent thermal insulation performance, some experts doped Pt into the CsxWO3 nanorods. The experts synthesized Pt-doped CsxWO3 nanorods with improved NIR shielding and transparent heat insulation performance by one pot solvothermal method using cheap sodium tungstate and cesium sulfate as raw materials. And the experts investigated the role of Pt-doping on the crystal structure, morphology and transparent heat insulation of the Pt-doped CsxWO3 products.

Cesium tungsten bronze nanopowder has a large forbidden band width and high carrier concentration so that it is often used to prepare balcony thermal insulating film with good transparent heat insulation properties. In addition, as the cesium tungsten bronze functional nano particles are relatively inexpensive, non-toxic and non-polluting, the experts believe that cesium tungsten bronze (CsxWO3) is very likely to replace tin-doped antimony (ATO), indium tin oxide (ITO) and other transparent heat insulation materials.

Cesium tungsten bronze nanopowder, as a type of MxWO3, has excellent near-infrared shielding properties, so it is often used to prepare living room thermal insulating film. And the prepared smart film will have excellent heat insulation and UV shielding effect. Also, it protects your privacy. And it is anti-glare. After applying such a transparent film on your glasses of living room, you will have cool springs and warm winters.

There are a series of multifunctional near-infrared shielding-photocatalytic nano films. And the study thermal insulating film of nano cesium tungsten bronze is the most popular one in these NIR shielding materials as it is a new type of environmentally friendly functional material with the highest NIR shielding performance.

Nano cesium tungsten bronze is a preferred functional material for the preparation of kitchen thermal insulating film. And it is the special optical properties of cesium tungsten bronze that makes the obtained transparent heat-insulating film integrate the advantages of heat insulation, heat preservation, anti-explosion, environmental protection and energy conservation.

Cesium tungsten bronze nanopowder, as a small size functional nanomaterial, is mainly applied for preparing sun room thermal insulating film. And the prepared smart film is often used to the sun room with a lot of glasses, thereby cooling the glass room and reducing energy consumption. According to the experts, the cesium tungsten bronze (CsxWO3) is a reduced compound, and there are W5+ and W6+. Also, it is the co-existence of W5+ and W6+ that makes the CsxWO3 show excellent near-infrared shielding performance.

Cesium tungsten bronze nanopowder for preparing office building thermal insulating film shows a strong near-infrared optical absorption and a high visible light transmittance. In recent years, the experts found that CsxWO3 nanocrystals displayed strong near-infrared optical absorption with a high molar extinction coefficient, thus generated significant amounts of heat upon excitation with near-infrared light.

Cesium tungsten bronze nanopowder is regarded as the best functional material for preparing nano heat insulating film as it has strong near-infrared optical absorption with the wavelength in the range of 780-2500 nm. Also, the cesium tungsten bronze (CsxWO3) is a novel NIR absorbent for PTA treatment of human cancer. The experts have developed PEGylated homogeneous CsxWO3 nanorods with broad photo-absorption (780-2500 nm).

Cesium tungsten bronze nanopowder has great potential in the preparation of nano heat insulating coating. And it is a new type of thermal insulation coating that is expected to replace ITO coatings. It is reported that the Cs0.33WO3 nanoparticles have the hexagonal structure. And owing to the free electrons or polarons, the Cs0.33WO3 nanoparticles exhibited a strong absorption property in the near-infrared (NIR) region.
