中文摘要：针对原位聚合的纱线连续导电处理方法存在原料利用率低的问题,通过改进了制备工艺,制备了聚对苯二甲酸丙二醇酯/聚苯胺(PTT/PANI)复合导电纱线,研究了氧化剂浓度对复合导电纱线导电性能以及力学性能的影响关系。结果表明:利用该法可以连续制备高电导率的PTT/PANI复合导电纱线,随着氧化剂浓度的提高,PTT纱线表面聚苯胺电导率先增大后降低,但纱线电导率逐渐提高趋于稳定。在大拉伸条件下,纱线电阻随拉伸的增大而增大,并成指数关系。在小应变拉伸-回复循环条件下,复合导电纱线的电阻变化较为复杂。复合导电纱线的断裂强力和断裂伸长率较处理前有所下降,初始模量有所增大。

外文摘要：Aiming at the problem of the continuous conductive treatment method of yarns prepared by in-situ polymerization on low utilization ratio of raw materials, an improved process was presented to prepare conductive polytrimethylene terephthalate （PTT） /PANI composite yarns, and the electrical and mechanical properties thereof were studied in detail. The results indicated that high conductivity PTT/ PANI composite yarns can be continuously prepared by the improved process. The conductivity of PTT increased first and then decreased, but the conductivity of the composite yarns increased and finally trended to be stable approximately, with the increase of the oxidant APS concentration. The resistance increased exponentially with the stretching of the composite yarn in large-strain. And the resistance change is complicated during the small strain stretch-recovery cycles. The breaking strength and breaking elongation of PTT yarns decreased and the initial modulus increased after the conductive treatment.
