以一种新型的双子表面活性剂6,6'-(丁基-1,4-二基双氧)双(3-壬基苯磺酸)(9BA-4-9BA)作为掺杂剂制备聚苯胺导电纤维,并与用2-丙烯酰胺基-2-甲基丙磺酸(AMPSA)掺杂的聚苯胺纤维的性能进行比较,探讨了聚苯胺分子量、纺丝原液的浓度、掺杂剂种类、凝固浴、牵伸工艺对纤维形貌和导电性能的影响.研究表明,质量分数为14%的AMPSA掺杂聚苯胺的二氯乙酸溶液在丙酮凝固浴中得到的初生纤维的电导率达到1.77S/cm,而质量分数为14%9BA-4-9BA掺杂聚苯胺的二氯乙酸溶液在9BA-4-9BA/丙酮凝固浴中得到的初生纤维及1倍牵伸纤维的表面形貌光滑规整,电导率分别为0.39 S/cm和1.14 S/cm.
