Preparation and Characterization of SiO₂/VO₂ Composite Particles

Abstract:

In order to enhance the visible transmittance, a compact silica film was successfully coated on the surface of VO2 particles by the sol-gel method, using sodium silicate as the coating agent and hydrochloric acid as the neutralization agent. The composition, structure, surface bonding mode and the visible transmittance of the products were characterized by means of XRD, SEM, FTIR and UV-Vis. The results showed that SiO2/VO2 composite particles can produced by this method, and the visible transmittance was higher than the pure VO2. It was a basic study in the applications of the smart coatings based on VO2 powders.
