摘要：
Flexible magnetite (Fe(3)O(4)) based film electrodes were fabricated by combining facile wet chemistry approaches with a cost-effective spray deposition route. One-dimensional Fe(3)O(4) nanowire and pyrrole treated Fe(3)O(4) nanowire electrodes composed of randomly oriented interpenetrating networks exhibited a high capacitance of 106 F g(-1) and 190 F g(-1) respectively along with excellent electrochemical stability in an aqueous electrolyte. The supercapacitor configurations and the scalable fabrication technique provides a new solution for large-scale production of printable and flexible energy storage devices.
