Paper Abstract

In this manuscript, we reported the preparation and characterization of Fe3O4/Epoxy nanocomposites. Structural characterizations were given by powder X-ray diffraction. The magnetic performance of pure Fe3O4 nanoparticles in the resulting composites was investigated by vibrating sample magnetometer. The coercivity of Fe3O4 nanoparticles in the composites has no obvious change, while the saturation magnetization of pure Fe3O4 nanoparticles in the composites increased from 42 emu/g to 60 emu/g with its content increasing. Such content-dependent behavior in the saturation magnetization is attributed to the 'Fe3O4-Epoxy' interfacial interaction and 'Fe3O4-Fe3O4'interparticles magnetic interaction.
