PEDOT nanowires of different size and morphology were successfully synthesized in aqueous solution via lithographically patterned nanowire electrodeposition (LPNE) in order to establish a direct relationship between the synthesis conditions and the properties. Optical microscopy, atomic force microscopy (AFM), cyclic voltammetry and electrochemical impedance spectroscopy (EIS) are utilized to characterize the size, morphology and electrochemical properties of the resulting PEDOT nanowires. Optical microscopy and AFM show that the various electrodeposition parameters (deposition methods, deposition voltage, deposition time, template size, etc.) have a great impact on the materials properties of the prepared nanowires. EIS measurement demonstrates that those nanowires exhibit exceptional capacitive property compared to that of commercial capacitors and polymer dispersion capacitors.
