摘　　要：以聚丙烯腈(PAN)和碳纳米管(CNT)为原料,通过静电纺丝制备CNT/PAN纳米纤维膜作为柔性超级电容器电极材料。通过添加不同含量(1%、2%、3%、4%)的CNT,对比电极材料的纤维直径分布范围和CV、GCD、EIS曲线。结果发现,当CNT的添加量为2%时,纤维平均直径最小,为78.67nm。该电极在0.1mA/cm^(2)的充放电电流密度下,样品的放电时间为5.75s,放电比电容达到1.150mF/cm^(2)。Using polyacrylonitrile(PAN) and carbon nanotubes(CNT) as raw materials,CNT/PAN nanofiber films were prepared by electrospinning as electrode materials for flexible supercapacitors.By adding different contents(1%,2%,3%,4%) of CNT,the fiber diameter distribution and CV,GCD,EIS curves of the electrode materials were compared.The results showed that when the amount of CNT was 2%,the average diameter of the fiber reached the minimum of 78.67nm.The discharge time of the sample was 5.75s and the specific discharge capacitance was 1.150mF/cm^(2) at the charge and discharge current density of 0.1mA/cm^(2).
