The CFP serves as not only a sacrificial reductant and converts aqueous permanganate (MnO 4 -) to insoluble MnO 2 in this reaction, but also a substrate material and guarantees MnO 2 deposition on the surface. The electrochemical properties were examined by cyclic voltammograms (CV), galvanostatic charge/discharge, and electrochemical impedance spectroscopy (EIS) in a three-electrode cell. According to the CV results, the ordered MOWAs yield high-capacitance performance with specific capacitance up to 274.1 F g -1 and excellent long cycle-life property with 95% of its specific capacitance kept after 5000 cycles at the current density of 0.1 A g -1. The high-performance hybrid composites result from a synergistic effect of large surface area and high degree of ordering of the ultrathin layer of MnO 2 nanowhisker arrays, combined with the flexible CFP substrate and can offer great promise in large-scale energy storage device applications. © The Royal Society of Chemistry 2012.||Source Title:||Journal of Materials Chemistry||URI:||http://scholarbank.nus.edu.sg/handle/10635/97888||ISSN:||09599428||DOI:||10.1039/c2jm16419a|
