摘要: 

以熔体纺丝方法制备了碳黑/聚酯(CB/PET)导电纤维, 分析了偶联剂对CB/PET纤维渗流阈值和Tg的影响, 研究了碳黑含量与CB/PET纤维热性能和导电性能的关系。结果表明碳黑经偶联剂处理后, CB/PET纤维的渗流阈值和Tg均有所降低; 碳黑含量对CB/PET纤维的性能影响显著, 即随碳黑含量增加, CB/PET纤维的正效温度系数效应向高温移动; 当碳黑含量为11%时, CB/PET纤维表现为较明显的正效拉力系数效应。

Abstract

Carbon black/polyester (CB/PET) electrically conductive fibers were prepared by meltspun method. The effect of coupling agent on the percolation threshold concentration and Tg of CB/PET fiber was discussed, and the relationship of CB content with thermal and electrical properties of CB/PET fibers was investigated. The results showed that percolation threshold content and Tg of CB/PET fiber were decreased after CB being treated by coupling agent. And CB content has a strong effect on the properties of CB/PET fiber, i.e. the positive temperature coefficient effect of CB/PET fiber moves to
higher temperature with CB content increasing; CB/PET fiber has a strong positive strain coefficient effect when CB content is 11%.
