Preparation of Nanometer Silica-Acrylate Composite Emulsion through Mini-Emulsion Polymerization

Abstract

In this work, the nanometre silica-acrylate composite emulsion was successfully prepared by the method of mini-emulsion polymerization. The effect on particle size by the amount of emulsifier and silica was investigated, and the property of the prepared silica-acrylate composite mini-emulsion was characterized by the stress strain. Results showed that the introduction of silica had no evident effect on the molecular weight and molecular weight distribution. With the increase of SDS concentration, the average particle size of the mini-emulsion decreased. The stress-strain curve showed that the tensile stress elongation and modulus of the polymer increased significantly when the silica was introduced, demonstrating the inorganic nanomaterial effect on the acrylate material.
