Cs doped tungsten oxide nanopowder, or cesium tungsten bronze nanoparticles, may be used to prepare an environmentally friendly thermal insulation masterbatch. According to experts, the obtained masterbatch has excellent properties such as high temperature resistance, high heat insulation, water resistance, and ultraviolet ray blocking property, etc. So, the masterbatch of cesium tungsten bronze nanoparticles can be used for preparing an environmentally friendly heat insulation film.

In this regard, experts say that the nanopowder of the nano cesium doped tungsten oxide raw material needs to be treated by a mechanical physical dispersion process to minimize the agglomeration of the nanopowder particles, so that the particles are uniformly dispersed uniformly. The so-called mechanical physical dispersion process generally includes mechanical agitation dispersion, ultrasonic dispersion, and high energy treatment. Among them, mechanical agitation dispersion mainly includes ball milling, high-speed stirring, sanding and other dispersion processes. In a word, nano grain size cesium tungsten bronze can be prepared by many preparation methods.
