Cs Doped Tungsten Oxide Nanopowder Applied for Thermal Insulation Coating

Cs doped tungsten oxide nanopowder may be use to produce thermal insulation coating for applying in heat insulating glass. What should be noted is that considering the size and existence of cesium doped tungsten oxide nanoparticles in a suitable solvent, it is necessary to pre-treat these nanoparticles, such as physical modification or chemical modification, to improve the stability of particles in the solvent.

So, what is physical modification? In the physical modification, the dispersing aid is mainly adhered to the outer layer of the cesium doped tungsten oxide nanoparticles by electrostatic interaction, and the outer layer of the nano particles cannot be adjacent to the adjacent particles due to being surrounded by the auxiliary agent, thereby hindering the tendency of the particles to build up between the particles, allowing the particles in the solvent to be stably present. What is chemical modification? Chemical modification, that is, chemical coating, refers to the bonding of a silane coupling agent, an organic acid, and a polymer molecule to the surface of the cesium doped tungsten oxide particle by chemical bonding, thereby weakening the surface energy of the nanoparticles, and thereby enhancing the stability of the nanoparticles.
