Patent ID: 8840771

Claim:
An electrochemical method for producing a nanofibrilar poly(3,4-ethylenedioxythiophene) (PEDOT) layer of nanofibers of PEDOT on an ITO electrode, comprising the steps of: a) cleaning an ITO electrode consecutively with chloroform, isopropanol and deionized water; b) preparing an aqueous solution of surfactant in 0.5 M NaNO 3 electrolyte; c) solubilizing 3,4-ethylenedioxythiophene (EDOT) in the surfactant/NaNO 3 solution; d) polymerizing the EDOT from the prepared solution on the surface of the ITO electrode by applying anodic oxidative current; and e) washing the deposited PEDOT layer with deionized water and drying the PEDOT layer at 60° C., wherein the surfactant forms cylindrical micelles, interconnected worm-like micelles or bilayers and the polymerized PEDOT layer has a nanofibrilar morphology.
