摘要：

The conductive poly(3,4-ethylenedioxythiophene): p-toluene sulfonate (PEDOT : PTS) films were prepared by gas-phase polymerization using CVD technique. PEDOT: PTS films with better electrical performance were produced by the additional doping with O-2 plasma after vapor phase polymerization. The mechanism for this conductivity enhancement is studied through surface structural analyses using Raman and X-ray photoelectron spectroscopy (XPS). The increase in conductivity is likely to be due to the generation of new functional groups such as carboxyl and hydroxyl groups that are acted as a dopant and the removal of the impurities on PEDOT: PTS surface with plasma treatment (C) 2009 Elsevier B.V.
