| Abstract: | Composite of conducting polyaniline(PAn) doped by dodecylbenzenesulfonic acid(DBSA) with Fe 3O 4 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 Fe 3O 4 nanoparticles possesses a good electrical conductivity and magnetic susceptibility as well as high transmittance. |
