Cs0.32WO3 particles may be used to prepare transparent thermal insulation material, such as thermal insulation coating and thermal insulation film, and thus be applied to architectural glass. Among them, the raw material particles used are cesium tungsten bronze nanoparticles, whose particle size is similar to that of colloidal particles. So, the dispersion stability of Cs0.32WO3 nanoparticles can be studied by the stability theory of colloids, such as the theory of electrostatic steric stabilization. So, what is the theory of electrostatic steric stabilization?

Experts say that the theory of electrostatic steric stabilization combines the theory of DLVO and stability theory of space steric hindrance. The surface of the particle adsorbs a layer of polymer molecules with a strong charge. When the particles are far away, the charged polymer generates a repulsive force by the same charge carried by itself. At this time, the electrostatic stability is dominant. If the particles are close, the particles are closer. The particle agglomeration can be prevented by steric hindrance. And steric hindrance is dominant.
