IN SITU POLYMERIZATION OF CONDUCTING POLY(3,4-ETHYLENEDIOXYTHIOPHENE)

摘要

Conducting poly(3,4-ethylenedioxythiophene) films are prepared upon solvent removal using an easily processable metastable solution of monomer and oxidant. This method allows the casting and spin-coating of films on conducting as well as insulating substrates with conductivities as well as optical and redox properties similar to those reported for chemically (vapor phase) and electrochemically synthesized thin films. Morphological characterization of spin coated poly(3,4-ethylenedioxythiophene) films suggest that they are smooth, uniform and free of pinholes on the micron scale. These films show conductivities in the range of 0.03 to 5 S/cm.
