归纳总结了静电纺丝聚丙烯腈纤维的制备及其在电化学超级电容器中的应用研究进展,根据所得材料的形貌与成分进行分类,分为多孔PAN基碳纳米纤维、掺杂PAN基碳纳米纤维和复合PAN基碳纳米纤维3大类,重点介绍如何采用不同处理方法在所得纤维上造孔、掺杂和复合,从而提高其电化学储能性能,并剖析了各种方法存在的优缺点,指出了进一步的改进提高方向。

In this paper, the research progress on preparation of polyacrylonitrile fiber by electrostatic spinning method and its application in electrochemical supercapacitor was summarized. According to the morphology and composition of the obtained materials, the obtained materials have be divided into three kinds, porous carbon nanofibers based on PAN, doped carbon nanofibers based PAN and carbon nanofiber composite based PAN. This paper focuses on how to carry out the works of pore forming, doping and compounding on the PAN fibers with different methods and thus how to enhance their electrochemical energy storage performances. And at the same time, the improvement directions are brought out based on the discussion in detail on the advantages and disadvantages of the methods mentioned above.
