摘　　要：对十二烷基苯磺酸 (DBSA)掺杂的导电聚苯胺 (PAn-DBSA)的氯仿溶液 ,在 p H为中性的条件下 ,采用“修饰 -再掺杂 (Modification-re-doped)法”合成了含有 Fe3O4 磁性纳米颗粒的导电聚苯胺复合物的有机溶液 .用 FTIR,XRD,TEM,UV-Vis和 SQUID等对所得复合物进行了表征 ,结果表明 ,该复合物呈现超顺磁性和半导体的导电性 。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.
