Nano CsxWO3 Powder Applied for Thermal Insulation Masterbatch

Nano CsxWO3 powder, or nano particle size cesium tungsten bronze powder, may be applied for preparing thermal insulation masterbatch. That is because the cesium tungsten bronze nano particles has special internal tunnel structure and carrier transport characteristic, and therefore it has many excellent optical properties such as photochromic property and light selective permeability.

The masterbatch prepared by using CsxWO3 nano powder as a raw material is a functional masterbatch with excellent thermal insulation performance (near-infrared shielding performance), which can be applied to the preparation of heat insulation film. And the prepared thin film is applied to architectural glass and automobile glass where require high heat insulation and high light transmission. In addition, some experts have studied the choice of light transmission mechanism of cesium tungsten bronze and found that the absorption of light waves in different wavelength bands can be changed by changing the concentration of free electrons inside the cesium tungsten bronze lattice. In other words, the improvement of the thermal insulation property of the masterbatch can be achieved by changing the concentration of free electrons of CsxWO3.
