Large-area network of polyaniline nanowires prepared by potentiostatic deposition process

Polyaniline nanowires (mean diameter 30-60 nm) have been deposited directly on a stainless steel electrode by the potentiostatic process. This procedure resulted in the large-area (1 × 1 cm) three-dimensional network of polyaniline nanowires. The nanowire's morphology can be controlled by means of appropriate deposition condition. A possible growth process of the formation of the polyaniline nanowire network is proposed.
