Nanoparticles of polystyrene/T-Fe2O3 composites were prepared by method of insertion in sodium dodecylbenzene sulfonate(SDBS) micellar system. The orange T-Fe2O3 particles of about 6 nm were first prepared from 0.25 mol/L FeCl2 and (NH3)2CO3 in 0.1% surfactant solution at pH=4,105℃ for 10 h. The title nanoparticles were prepared then in conditions of SDBS: styrene: H2O(mass fraction)=0.1:1:9, 85℃, 8 h, using ammonium persulfate(APS) as an initiator. The composite nanoparticles sized in 20~50 nm and showed magnetic property.
