采用化学氧化聚合法制备了聚苯胺纳米线/有序双峰介孔碳(PANI/OBMC)复合材料。结构和形态表征表明，在OBMC表面生长了直径为20-30 nm的聚苯胺纳米线阵列。PANI/OBMC复合材料的双峰孔分布和层次化纳米结构使其具有高比表面积599×m~2/−~1。采用循环伏安和恒电流充放电技术研究了PANI/OBMC复合材料作为超级电容器电极材料的电化学性能。PANI含量为60wt%的层状复合材料具有最高的比电容517F/g−1和优异的循环稳定性，1000次循环后的容量保持率为91.5%。初级介孔和丰富的小孔共存有利于电解液的快速渗透，独特的层次化结构有利于离子的扩散，缩短了电荷转移距离，使PANI/OBMC-60具有优异的电化学性能。
A facile strategy is developed for the synthesis of hierarchical polyaniline nanowires/ordered bimodal mesoporous carbon (PANI/OBMC) composites via chemical oxidative polymerization. Structural and morphological characterizations indicate that the polyaniline nanowire arrays with 20–30 nm diameters are grown on the surface of the OBMC. The bimodal pore distribution and hierarchical nanostructure endow the PANI/OBMC composite with high surface area of 599 m2g−1. Electrochemical performance of the hierarchical PANI/OBMC composite as supercapacitor electrode materials has been evaluated by cyclic voltammetry and galvanostatic charge–discharge techniques. The hierarchical composite with 60 wt% PANI possesses the highest specific capacitance of 517 F g−1and outstanding cycling stability with a capacitance retention of 91.5% after 1000 cycles. The coexistence of primary mesopores and abundant small mesopores is in favor of the fast penetration of electrolyte and the unique hierarchical structure facilitates the ion diffusion and shortens the charge transfer distance, which lead to superior electrochemical performance of PANI/OBMC-60%.
