碳纤维具有比表面积大、导电性好、化学稳定性好等特点,是制作超级电容器电极材料的良好原材料。本文对近年来国内外应用于超级电容器电极材料的碳纤维表面处理技术进行了汇总,比较了电化学法、化学合成法、物理涂覆法三种直接在碳纤维表面进行处理方法的优缺点,并介绍了对碳纤维处理后再次碳化和对碳纤维进行杂原子掺杂两种对前驱体进行处理从而进行表面改性的方法。本文将为设计和制造不同用途的碳纤维超级电容器复合材料提供有价值的指导。

Carbon fibers are good raw materials for supercapacitor electrode because of their large specific surface area, good electrical conductivity and good chemical stability. This paper summarized the surface treatment technologies of carbon fibers applied to supercapacitor electrode materials in recent years, comparing the advantages and disadvantages of three methods of treatment on the surface of carbon fibers by electrochemical method, chemical synthesis method and physical coating method, and introducing two methods of treating precursors and thus surface modification by carbon fiber treatment and carbon fiber heteroatom doping again after treatment. This paper will provide valuable guidance for the design and fabrication of carbon fiber supercapacitor composites for different applications.
