摘　　要：采用单体聚合法以FeCl3为引发剂进行噻吩的聚合反应,得到了导电性好的-γFe2O3/聚噻吩纳米复合材料。红外、透射电镜、穆斯堡尔谱等研究表明-γFe2O3与聚噻吩之间有着一定的相互作用。复合材料的导电性明显高于纯的聚噻吩样品,随着-γFe2O3含量的增加,复合材料的导电性呈增大趋势。We report here the preparation of an electrically conducting γ-Fe2O3/polythiophene nanocomposites by using FeCl3 as initiator. The results of FTIR, TEM, and Moessbauer spectra show that strong interaction happens between γ-Fe2O3 and polythiophene. The room temperature conductivity of γ-Fe2O3/polythiophene was higher than that of pure polythiophene,and go on increasing as the γ-Fe2O3 content in the composites increased.
