中文摘要：
以过硫酸铵((NH4)2S2O4)为氧化剂,盐酸作为质子酸掺杂,采用化学氧化聚合法合成了导电聚苯胺,研究了氧化剂用量、掺杂质子酸浓度、反应温度和反应时间对聚苯胺导电性及产率的影响,用X射线衍射(XRD)、扫描电子显微镜(SEM)、傅立叶红外变换光谱(FTIR)、紫外-可见光谱(UV-Vis)分析研究了聚苯胺的结构和形貌特征。结果表明,制备导电性好、产率高的掺杂态聚苯胺最佳实验条件为:n((NH4)2S2O4)/n(An)为1︰1,盐酸浓度为1 mol/L,反应温度为5℃,反应时间6 h。在此条件下,制备得到的聚苯胺电导率大于27 S/cm,产率在95%以上,颗粒表现出一定的结晶性。
