中文摘要：为提高涤纶的导电性能,以涤纶长丝纱为基材,采用基于苯胺原位聚合的连续导电方法,制备涤纶/聚苯胺(PET/PANI)复合导电纱。探讨了导电处理工艺氧化剂浓度、处理掺杂酸和苯胺的浓度及处理速度对导电纱导电性能的影响,并测定与分析了纤维的表面形貌、化学结构、热学性能及力学性能。结果表明:经导电处理后,PET纱线表面及内部包覆并填充了导电态PANI;反应液浓度及处理速度对PET/PANI复合导电纱的电导率有较大影响,制得的导电纱电导率最高可达1.5 S/cm以上;PANI的存在降低了PET的热稳定性;相比PET纱,PET/PANI复合导电纱的断裂强度和断裂伸长率有小幅增长,但初始模量却有较大的下降。

外文摘要：In order to improve the conductivity of polyester （PET） fiber, a novel method based on in- situ polymerization of aniline for the continuous preparation of conductive yarn was presented, and conductive polyester/polyaniline （PET/PANI） composite yarns were prepared by this method. The influence of parameters of conductive treatment such as concentration of oxidant, doping acid and aniline and processing speed on the electrical conductivity of composite yarns was discussed, and the morphological structure, chemical structure, thermal-gravimetric performance and mechanical properties were also studied. The results indicate that the substrate.yarns are coated and filled with conductive PANI. The concentration of reaction mixtures and processing speed greatly affect the conductivity of conductive PET/PANI composite yarns, and the conductivity can reach above 1.5 S/cm. The thermostability of the treated yarns is decreased due to the existence of PANI. Compared with the substrate yarn, the breaking strength and breaking elongation of the treated yarns are increased slightly while the initial modular decreases greatly.
