【摘 要】 为改善PEDOT :PSS/PVA 复合纤维的导电性,在PEDOT :PSS 和PVA 混纺水溶液中 添加不同含量的乙二醇(EG),采用湿法纺丝制备复合导电纤维。探究了 EG 的添加量对复合纤维表面 形貌及力学、导电性能的影响。采用包括电子单纤维强力仪在内的多种方法对纤维进行测试。结果表 明:EG 可改善复合纤维的外观形貌,使纤维表面裂纹消失趋于光滑,且随EG 添加量的增加,复合纤维 的导电性逐渐增强,在EG 添加量为10%时,电阻率从(3. 0 +0. 2) MQ 下降到(0. 6 + 0. 1) MQ,纤维 的拉伸强度从(180+15) MPa 提高到(246 + 10) MPa 。拉曼光谱表明,EG 可使PEDOT 主特征峰红 移,使PEDOT 主链发生苯醌转变。

[Abstract ! In order to improve the electrical conductivity of PEDOT : PSS/PVA composite fibers , ethylene glycol (EG) was added into PEDOT : PSS/PVA blended spinning formulation. Effect, of the amount, of EG on the surface morphology and mechanical and electrical properties of the composite fibers were investigated. And the fibers were tested and characterized by several techniques including electronic single-fiber strength meter. Results show that the doping of EG improves the appearance of the composite fiber and make the surface cracks of the fiber disappear. When the content of EG increases , the conductivity of the composite fiber gradually increases , and when the doping content of EG increase to 10%, the resistivity decreases from (3. 0士0. 2) MQ to (0. 6 + 0. 1 ) MQ, and the tensile strengt
