Cs0.32WO3 Particles Applied for Thermal Insulation Film

Cs0.32WO3 particles for thermal insulation film are cesium tungsten bronze nanoparticles. The particle size of such nano particles is similar to that of colloidal particles. Therefore, the stability theory of colloids, such as steric stabilization theory, can be used to study the dispersion stability of cesium tungsten bronze nano particles. So, what is the theory of steric stabilization theory?

Experts say that systems for adding high molecular polymers as dispersants can be explained by the theory of steric stabilization. The anchoring groups of the dispersant molecules are adsorbed on the surface of the solid particles, and the solvation chain thereof is sufficiently extended in the medium to form a steric layer, acting as a stable portion, hindering collision agglomeration and gravity precipitation of the particles. The steric stabilization effect must satisfy two conditions:
1.0 The anchoring group produces a large area of strong adsorption on the surface of the particle;
2.0 The solvation chain is fully extended to form a certain thickness of the adsorption steric layer.
