Study on Dispersion Polymerization Process of Silica Aerogel/Polystyrene Core-Shell Composite Particles

Full Text(PDF, 1890KB)

Author: Gangqiang Geng, Suqing Wen, Huan Wang

Abstract: Silica aerogel/polystyrene core-shell composite particles have been synthesized by dispersion polymerization. In the chemical synthesis microwave irradiation heating method is used to induce the polymerization. And study on the influence of the mass ratio of the silica aerogel and styrene monomer on the coating rate of the composite particles. Then study on the content of the initiator AIBN on the density of the composite particles and the conversion rate of the styrene monomer. Finally composite particle is confirmed to be a kind of strawberry shaped core-shell composite structure by SEM and energy spectrum analysis.

Keywords: Silica aerogels; Polystyrene; Core-shell structure; Dispersion polymerization
