Nano Cs Doped Tungsten Oxide Applied for Thermal Insulation Paper

Nano Cs doped tungsten oxide, or nano cesium tungsten bronze, or Cs0.33WO3 nanoparticles, may be applied for preparing a new type of transparent thermal insulation paper. That is because cesium tungsten bronze nanoparticles are a high-density free electron gas-type material that has high concentration of free carriers. So, it has excellent visible light transmission and near-infrared shielding performance.

As a good near-infrared shielding material, the new transparent heat insulation material of cesium tungsten bronze nano particles has a wide application prospect in the automotive and construction industries. According to experts, the cesium tungsten bronze is one of the tungsten bronze types. The hexagonal structure tungsten bronze has a large tunnel structure size, so that a larger radius of Cs ions can be infiltrated to form cesium tungsten bronze (CsxWO3). Experts also said that the concentration of x ions that can penetrate into the hexagonal structure is 1/3, which is generally less than 1/3.
