Název v původním jazyce

Controlled synthesis of hierarchical polyaniline nanowires/ordered bimodal mesoporous carbon nanocomposites with high surface area for supercapacitor electrodes

Popis výsledku v původním jazyce

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 m(2) g(-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(-1) and 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 hierarchic
