文摘
Highly uniform polyaniline-Ag nanocable arrays (NCAs) had been electrodeposited into the anodic aluminum oxide (AAO) template for supercapacitor studies. Each nanocable has the average values dimensions, with approximately length of 20 ¦Ìm and diameter of 100 nm. The supercapacitor using PANI-Ag nanocable arrays as electrode showed excellent stability over a long cycle-life by cyclic voltammogram tests. The capacitance value of the electrode was as high as 850 Fg?1 at 10 mVs?1 sweep rate, and there was a decrease in capacitance with an increase of current density. These interesting results indicated that PANI-Ag NCAs could be an ideal alternative to carbon based electrodes, regular conducting polymers and metal oxides for the fabrication of supercapacitor.
