摘要/Abstract

摘要： 采用原位聚合法制备了PTT/PANI复合导电纤维，探讨了反应时间、等离子预处理、拉伸状态对复合纤维电导率的影响，并研究了PTT/PANI复合纤维的表面形貌、热学性能及力学性能。结果表明：纤维表面形成的聚苯胺导电层赋予了纤维优良的导电性能，其电导率可达10-2S/cm；对纤维进行氧气等离子预处理可明显提高复合纤维的电导率；反应时间对复合纤维的电导率也有较大影响；PTT/PANI复合纤维经拉伸后导电性能明显下降。复合纤维的热稳定性在高于430℃时优于基质纤维并在一定程度上提高了基质纤维的力学性能。

Abstract: PTT/PANI composite conductive fibers were prepared using in-situ polymerization. The effects of reaction time, plasma pre-treatment, stretching on the electrical conductivity of composite fiber were investigated. The surface morphology, thermal characterization and mechanical characterization of composite fiber were also studied. The results indicated that PTT/PANI composite fibers obtained by in-situ polymerization with good conducting property, and the electrical conductivity reached 10-2S/cm, and much higher electrical conductivity would reached by base fiber’s oxygen plasma pre-treatment. Reaction time affects the electrical conductivity of PTT/PANI composite fiber obviously. The electrical conductivity of composite fiber declines significantly after stretching. The thermal stability of composite fiber is better than that of base fiber over 430℃, and the mechanical property of composite fiber is also better than that of base fiber.
