Abstract

Abstract:

Inorganic nanoparticles Fe₂O₃ in diameter of 3-5 nm have been assembled with polymer microspherer and then encapsulated in copolymer of St/BA/AA by polymerization process. Fe₂O₃ encapsulated microspheres can obtained through interaction between surface groups of the two component particles and by adjusting the pH value in the emulsion. Pre-treatment of the composite particles using a certain amount of surfactant before polymerization can give a good encapsulation.

Key words: Assembly, Fe₂O₃ nanoparticles, Encapsulated copolymerization
