Cesium Tungsten Oxide Particles Applied for Thermal Insulating Glass

Actually, cesium tungsten oxide particles for preparing thermal insulating glass are cesium tungsten bronze nanoparticles. In this regard, experts say that the dispersion of functional particles of cesium tungsten bronze will affect the thermal insulation properties of the final building transparent heat insulating glass. Therefore, it is necessary to carry out related treatment, such as chemical dispersion, on the cesium tungsten bronze nanopowder to improve the dispersibility of the nanoparticles.

Experts mentioned that chemical dispersion method is a more effective way to improve the dispersion of nanoparticles, which can be divided into surface modification method and dispersant dispersion method. Among them, according to the chemical reaction between the modifier and the surface of the nanoparticles, the surface modification method can be divided into two major categories: physical modification method and chemical modification method. So, what is the physical modification of the surface? The surface physical modification method is a method that adsorbing on the surface of the nanoparticles by van der Waals force, coordination bond or hydrogen bond, including surfactant method, surface coating method and surface deposition modification method. When the nanoparticles adsorb the surfactant, a repulsive force is generated between the nanoparticles, so the nanoparticles are well dispersed.
