Abstract

Abstract: A layer of elemental silver was electrodless plating coated on the surface of Fe3O4 forming Ag/Fe3O4. Subsequently, conductive polymer magnetic composites(PANI/Ag/Fe3O4) was prepared through in situ polymerization of PANI.When the amount of Ag/Fe3O4 was 20% of the mass of PANI,the conductivity of PANI/Ag/Fe3O4 composites was 0.85 S/cm and saturation magnetization was 16.34 emu/g.Ag/Fe3O4 hindered the decomposition of PANI and thus high decomposition temperature and thermal stability was obtained.
