Magnetic and conducting Fe3O4-polypyrrole nanoparticles with core-shell structure have been prepared in the presence of Fe3O4 magnetic fluid in aqueous solution containing dodecyl-benzene sulfonic acid sodium salt (NaBS) as a surfactant and dopant. Interaction and interactive mechanism between Fe3O4 nanoparticles and polypyrrole were studied by XPS, IR, UV and TG. The magnetic Fe3O4 nanoparticles can improve the thermal stability of Fe3O4-polypyrrole nanocomposites due to interaction between Fe3O4 particles and polypyrrole chains. The interaction between Fe and N, which mechanism may be the lonepair electrons of N atom in PPY chain interact with 3d orbit of Fe atom to form corm coordinate bond, which could reduce the energy level interval of pyrrole ring.
