摘要：
Magnetic composite particles were prepared via dispersion polymerization of styrene in the presence of gamma-Fe2O3 nanoparticles. The fabricated magnetic composite nanoparticles were dispersed into non-magnetic suspending media to be adopted for magnetorheological (MR) fluid, whose theological properties can be drastically changed in the external magnetic field. The MR efficiency of gamma-Fe2O3/polystyrene composite based fluid was examined by a rotational rheometer equipped with a magnetic field supplier. (C) 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
