| 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T_g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T_g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 melt-spun method.The effect of coupling agent on the percolation threshold concentration and T_g 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 T_g 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 f... |
