摘　　要：采用低分子量酚醛树脂/F127混合物填充多孔氧化铝模板孔道,制备了大尺寸介孔孔道、核-壳结构的介孔碳纳米纤维.分别以SEM、TEM及N2等温吸附-脱附观察分析样品形貌和孔结构参数.循环伏安与恒流充放电测定该介孔纳米纤维电极(阳极)的超电容性能.结果表明:介孔碳纳米纤维比电容明显增大,且在高扫速、大电流下具有良好的超电容特性.Two different mesoporous carbon nanofibers with large mesopore or core-shell structure were prepared by using the resol/F127 mixture to fill the AAO template. The morphology and structural parameters of the samples were characterized by SEM,TEM,and N2 adsorption-desorption analysis. The supercapacitive behaviors of the electrodes were tested by cyclic voltammetry and galvanostatic charge-discharge. The results show that the specific capacitances of mesoporous carbon nanofibers increased obviously and the fine supercapacitive performances were achieved at high scan rate or large current density.
