Cesium Tungsten Oxide Particles Applied for Transparent Thermal Insulation Material

Cesium tungsten oxide particles, which is also known as cesium tungsten bronze or cesium doped tungsten bronze, may be used to prepare a variety of transparent thermal insulation material, such as, architectural films, automotive films, architectural coatings, dispersions, and the like. Among them, thermal insulation coating of cesium tungsten bronze nanoparticles can achieve uniform dispersion of particles, and has good mechanical property and high visible light transmittance. The maximum light transmittance of such material can reach more than 89%. And thus it is believed that cesium tungsten oxide nanoparticles have certain application prospects.

In fact, there are several types of thermal insulation coatings, including shielding type coatings, radiation type coatings and reflection type coatings. China's research on shielding-type thermal insulation coatings began in the 1980s. Shielding-type heat insulation coatings are coatings that achieve thermal insulation performance through significant resistance to heat transfer. This is because such material with small thermal conductivity, loose internal structure and high porosity has a good resistance to heat transfer. Heat transfer is achieved by convection, radiation and molecular vibration heat conduction. Therefore, the thermal conductivity of the raw material is the determining factor of the thermal insulation performance of the heat insulation material. The smaller the thermal conductivity, the better the thermal insulation performance.
