In this Article, a facile and general method was afforded to prepare magnetite/polymer coreshell microspheres. The hydrogen bond interaction between the magnetite and a series of functional monomers was strong enough for coating polymer shells onto the magnetite microspheres. Various functional shells such as carboxyl, hydroxyl, amide, and ester were provided via the tune of the monomer during the polymerization. The P(MBAAm-co-MAA) shell-coated magnetic microspheres were loaded with a series of metal nanoparticles like Au, Ag, and Pd. Because of their high saturation magnetization values and easy preparation, these microspheres may be promising materials for catalysis. Further work is in progress.
