Electrochemical Deposition and Characterization of Doped Poly (3,4-Ethylene Dioxythiophene) for Potential Use as a Biosensor

In this study, conducting polymer films of poly(3,4-ethylenedioxythiophene) (PEDOT) were electrodeposited onto a platinum electrode from an aqueous micellar medium. The electroactivity of the undoped and doped PEDOT films were compared. The electrodeposition was characterised by cyclic voltammetry and galvanostatic mode from LiClO4 solution containing appropriate monomer concentrations and sodium dodecyl sulphate (SDS) as a wetting agent. The resulting polymer films were characterised using cyclic voltammetry in neutral phosphate buffer solutions, SEM and IR spectroscopy.
