摘　　要：传统对位芳纶纤维结构规整,表面改性困难,功能相对单一,通过干喷-湿法纺丝工艺,向对位芳纶前驱液中引入炭黑进行功能化改性,制备出对位芳纶/炭黑复合纤维。采用扫描电子显微镜、X射线衍射分析仪、傅里叶红外光谱仪对其形貌以及结构进行表征并采用热重分析仪、电子单纤维强力机、热红外成像仪探究对位芳纶/炭黑复合纤维的性能。结果表明:相比于未引入炭黑的对位芳纶纤维,对位芳纶/炭黑投料质量比为95∶5的复合纤维断裂伸长率增长了97.13%,而断裂强力保留率为73.82%,仍具有良好的热稳定性,此外在红外灯辐照7 min后,温度变化高达34℃,展示出良好的光热转换性能。The traditional para-aramid fiber structure is regular,making surface modification challenging and its functions relatively simple.To address this issue,para-aramid/carbon black composite fibers were prepared by introducing carbon black into the para-aramid precursor,followed by functionalization modifica-tion through a dry-jet wet spinning process.Scanning electron microscopy,X-ray difraction analysis,and Fourier transform infrared spectroscopy were used to characterize their morphology and structure.Additionally,thermogravi-metric analysis,electronic single fiber strength testing,and thermal infrared imaging were employed to investigate the properties of the para-aramid/carbon black composite fibers.The results show that compared to para-aramid fi-bers without carbon black,the composite fibers with a para-aramid/carbon black feeding ratio of 95:5 exhibited a 97.13%increase in elongation at break while retaining 73.82%of the original breaking strength.They also demon-strated good thermal stability,with a temperature change of up to 34℃after 7minutesof infrared lamp irradiation,indicating excellent photothermal conversion performance.
