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.
