聚苯胺/改性聚酯复合导电纤维的制备

Preparation of Polyaniline/Modified Polyester Composite Conductive Fiber

采用"原位"聚合法制备聚苯胺/改性聚酯复合导电纤维,分析盐酸浓度、氧化剂浓度、纤维在苯胺中的浸泡时间以及反应时间对纤维电导率的影响。研究结果表明,由改性聚酯纤维制得的导电纤维的导电性能较好,当盐酸浓度1.0mol/L,氧化剂浓度0.02mol/L,纤维在苯胺中的浸泡时间1h,反应时间1～2h时制得的纤维体积电阻率较佳。制备的导电纤维基本保持了原有的力学性能。

Polyaniline/modified polyester composite conductive fiber is prepared by in-situ polymeriza- tion. The optimum conditions of the preparation are studied. The effect of hydrochloride acid and oxidant concentrations, immersion and reaction time is investigated on the conductivity of the fiber. The results show that the conductivity of polyaniline/modified polyester composite conductive fiber is higher than the polyaniline/pure polyester composite conductive fiber, when the concentrations of HC1 is 1.0 mol/L, the concentrations of oxidant is 0.02 mol/L, the immersion time is 1 h, the reaction time is 1-2 h, the opti- mum conductivity of the fiber are obtained. In addition, the conductive fiber maintains good mechanical properties.
