Abstract

Abstract: Composite of conducting polyaniline(PAn) doped by dodecylbenzenesulfonic acid(DBSA) with Fe₃O₄ magnetic nanoparticles was synthesized in a neutral solution by a chemical method which was called "modification-re-doped" method. The composite of magnetic nanoparticles modified with doped PAn was synthesized by microemulsion. Then the composite was synthesized by emulsion polymerization extraction method. The composites were characterized by means of FTIR, XRD, UV-Vis, TEM, and SQUID. The results indicate that the composite with superpapramagnetic Fe₃O₄ nanoparticles possesses a good electrical conductivity and magnetic susceptibility as well as high transmittance.
