本文首次采用新型氧化剂对原煤进行氧化处理，提高了原煤在有机溶剂中的溶解度，为利用煤和静电纺丝制备纳米碳纤维提供了可能。此外，我们发现氧化煤的加入会导致纤维的内部连接。结果表明，当氧化煤的添加量为15wt%时，纤维具有较高的电导率，且当氧化煤的添加量为50wt%时，在三电极体系中，电流密度为1A g（-1）时，碳/聚丙烯腈纳米纤维的比电容为259.7F g（-1），循环性能良好。(C)2016由Elsevier Ltd.出版
In this paper, we firstly used a new oxidizing agent to treat raw coal and got an enhancement of the solubility in organic solvents, making it possible to prepare carbon nanofibers by using coal and electrospinning. In addition, we found that the addition of oxidized coal would cause the fibers to inner-connect. Results showed that when the addition of oxidized coal was 15 wt%, the fibers would show a high conductivity, moreover, the coal/PAN nanofibers containing of 50 wt% oxidized coal had a specific capacitance of 259.7 F g(-1) at a current density of 1 A g(-1) in three-electrode system, together with an excellent cycling performance.
