Magnetite hollow microspheres were successfully synthesized by a solvothermal route,using ethylene glycol(EG) as reaction solvent and FeCl3·6H2O and urea as the starting materials,and it was modified by sodium dodecyl benzene sulfonate(SDBS).Polyaniline/Fe3O4 magnetic hollow microsphere composites was prepared by emulsion polymerization,using sulfosalicylic acid(SSA) as emulsifier and doping agent and potassium persulfate as oxidant.Phase structure,morphology and magnetic properties of its corresponding products were characterized by X-ray diffraction(XRD),Fourier transform infrared spectroscopy(FT-IR),high-resolution transmission electron microscopy(TEM),and physical property measurement system(PPMS).The results showed that the composite was composed of the network structure of ribbon-like polyaniline in which flower-like Fe3O4 hollow microspheres were uniformly embedded,and the composite had good magnetic property.
