以十二烷基苯磺酸(DBSA)为表面活性剂和掺杂剂,通过乳液聚合的方法制备聚苯胺/聚乙烯醇(PA-NI/PVA)复合乳液用于静电纺丝,制备出超细复合纤维毡,通过SEM、XRD和力学测试表征PANI/PVA超细复合纤维毡的外观形貌、纤维直径、结晶度及其力学性能.结果表明:有机磺酸掺杂后的聚苯胺导电性能达到1.28 S/cm;1459 cm-1处醌环和苯环上的C=C伸缩振荡峰和1697 cm-1处醌环上C=N伸缩振荡峰的聚苯胺特征峰明显;YG006型电子单纤维强力机的测试发现,PANI/PVA纤维集合体的面密度对其力学性能的影响显著;当纺丝工艺条件设定为接收距离18 cm、电压24 kV时,PANI/PVA纤维直径达到600 nm,直径分布小于150 nm,PANI微颗粒分散于PVA纤维基体表面.
