Cs0.33WO3 thermal insulation paper, or Cs0.33WO3 heat insulation film, is a kind of transparent "paper" prepared using cesium tungsten bronze dingal nanoparticles as a raw material. In recent years, this new type of thermal insulation nano material has been widely used in the field of heat insulation of building glass. Therefore, some experts say that the nano particles of cesium tungsten bronze have broad application prospects.

And therefore, some experts have studied the effect of different dispersants on the visible-near-infrared light transmittance of Cs0.33WO3 film. The transmittance spectra of thermal insulation papers prepared by colloidal Cs0.33WO3 using different dispersant is shown in the above figure. It can be seen from the figure that the addition of coupling agent of organic titanate after ball milling has better dispersion effect on Cs0.33WO3 slurry. The particle size is uniform and the particle dispersion is good to make uniform and continuous particle arrangement on the film, thereby improving optical performance. That is to say, to obtain Cs0.33WO3 particles with excellent optical properties, it is necessary to add a dispersing agent before ball milling.
