界面聚合法制备纳米C_(60)/聚苯胺复合材料及其电学性能研究

Study on preparation and electric property of C_(60)/polyaniline composite by interfacial polymerization

依靠界面聚合法制备了C60/聚苯胺纳米复合物。透射电子显微镜表明C60/聚苯胺呈纳米纤维状;通过UV-vis光谱证实了C60和聚苯胺之间存在着π-π相互作用;四探针法测试表明C60/聚苯胺纳米复合物具有半导体电导特征,最高电导率可达3.5×10-4S/cm;热重分析表明,C60/聚苯胺复合物具有比纯聚苯胺高的热稳定性。

The C60/polyaniline（PANI）composite was prepared by interfacial polymerization method. The obtained composite showed a nano-fiber morphology detected by TEM. The π-＊π interactions between C60 and PANI were proved by UV-vis analysis. The nanocomposite showed the behavior of semiconductor, with the maximum conductivity of 3.5 × 10-4 S/ cm examined by four-probe method. TGA analyss showed that the composite had the higher thermal stability than the pure PANI.
