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1×10-2S/cm;对纤维进行氧气等离子体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温度高于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。PTT/PANI composite conductive fibers were prepared using in-situ polymerization. The effects of reaction time, plasma pre-treatment and stretching on the electrical conductivity of the composite fibers were investigated, as well as their surface morphology, thermal and mechanical properties. The results indicated that the polyaniline conductive layer formed on their surface rendered the fibers good conductive property, and the electrical conductivity reached 1 × 10^-2 S/cm. The conductivity of the fibers was significantly improved by oxygen plasma pre-treatment, remarkably influenced by reaction time, and obviously deteriorated by stretching. The thermal stability of the composite fiber is better than that of the substrate fiber over 430 ℃, and the mechanical property of the composite fiber is thus improved to a certain extent.
