摘　　要：在一元有机酸(甲酸、丁酸)溶液中,采用化学氧化聚合法制备了不同纳米结构的聚苯胺(PANI).结果表明:长链有机酸有助于聚苯胺纳米管的形成,且所得聚苯胺的热稳定性增加.通过对丁酸体系中不同反应阶段的溶液pH值与产物的形貌及红外光谱分析,得出有机酸分子形成胶束,在聚合苯胺时作为形成PANI纳米管的模板.Different nanostructures of the polyaniline （PANI） were fabricated by chemical oxidative polymerization in the solution of different monocarboxylic acids （formic acid and butyric acid）. The results showed that long-chain organic acids contribute to the formation of PANI nanotubes, and the thermal stabil- ities of the PANI also improved. It was proposed that micelles formed by the organic acid molecules as a ＂template＂ to synthesize PANI nanotuhes, by analyzing the relationship between the morphology and Infrared spectra （IR） of products and the pH of solutions at different reaction times.
