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pH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,并具有较好的透明性.

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.
