Cs0.32WO3 Particles Applied for Thermal Insulation Paper

Cs0.32WO3 particles may be used to prepare a transparent thermal insulation paper, that is, a heat insulating architectural film. So, the architectural glass applying with such film will have excellent near-infrared shielding property. Some experts have studied the effect of adding coupling agent of organic titanate before and after ball milling on the visible-near-infrared light transmittance of thermal insulation film of nano grain size Cs0.32WO3.

Experts said that, according to the experimental results, the peak of the coupling agent of organic titanate added before ball milling showed a red shift phenomenon and the near-infrared transmittance increased. This was due to the addition of a coupling agent before ball milling, which destroyed the surface alkoxy group during ball milling. And the steric hindrance is reduced, which is not conducive to the dispersion of Cs0.32WO3 nanoparticles. Therefore, the heat-insulating film of nano Cs0.32WO3 adding with a coupling agent of organic titanate after ball milling has more excellent near-infrared shielding performance.
