| Abstract: | The magnetic nanoparticles with perfect crystal and good dispersion were synthesized by the chemical coprecipitation method in the presence of oleic acid （OA） as the surfactant. The magmetic polymer microspheres Fe3O4/PMMA were prepared by monomer polymerizatioon hy using methyl methacrylate as the monomer（MMA）, DVB as the cross-linking agent and KPS as the initiator with the existence of the magnetic fluid. The magnetic polymer microspheres had the obvious core-shell structured and the size of the microspheres was about 500 nm. |
