Novel inner asymmetric composite microspheres were prepared by encapsulating surface-modified magnetic particles via mini-emulsion polymerization. Most of the surface-modified magnetic particles encapsulated into the polymer matrix aggregate in one side of each microsphere, while only a few particles randomly disperse in the remaining part. The magnetic content of these novel asymmetric composite microspheres is 46.7% and the saturation magnetization is 23.8 emu g^?1.
