摘　　要：研究对鳞片石墨粉和聚醚醚酮纤维实施改性处理,制备出酰氯化石墨烯和氨基改性聚醚醚酮纤维,并对两种材料进行接枝处理,最终制备出聚醚醚酮复合导热纤维。为验证该材料的导热性能和热稳定性,研究对其进行微观形貌观测、热扩散系数测试、DSC测试以及TGA测试等试验。根据试验结果可知,聚醚醚酮复合导热纤维中的酰氯化石墨烯能够形成连续的导热通路,可将聚醚醚酮纤维的导热系数提升4.8倍。除此之外,聚醚醚酮复合导热纤维还具有良好的热稳定性,其5%热失重温度高达536.9℃,可有效支持小型运动设备的高负荷运转。This paper aims to improve the thermal conductivity of polymer fiber materials for small sports equipment and maintain the stable operation of equipment under high load. In this regard, flake graphite powder and polyetheretherketone fibers were first modified to prepare acyl chloride graphene and amino-modified polyetheretherketone fibers, and the two materials were grafted to finally prepare polyetheretherketone composite thermal conductive fibers. Then, the microscopic morphology observation, thermal diffusivity test and both DSC and TGA tests were conducted to verify the thermal conductivity and thermal stability of this newly prepared material. According to the test results, the acyl chloride graphene in the polyetheretherketone composite thermal conductive fiber can form a continuous thermal conductivity path, which can increase its thermal conductivity by 4.8 times. In addition, the polyetheretherketone composite thermal conductive fiber also has a good thermal stability, and its 5% thermal loss temperature is as high as 536.9 ℃, which can effectively support the high-load operation of small sports equipment.
