发明名称 Surface treatment method for magnetic particles
摘要 A surface treatment method for magnetic particles is disclosed, which comprises the steps of activating magnetic particles by application of heat thereto, treating the surface of the magnetic particles with a reactive silane coupling agent, bringing the treated magnetic particles into contact with at least one polymerizable vinyl-type monomer, polymerizing the monomer to form a polymer, and coating the surface of the magnetic particles with the polymer.
