Abstract
Highly conducting poly(3,4-ethylenedioxythiophene) films have been electrosynthesised in aqueous medium. The highest in situ conductivity of the films obtained in pure aqueous medium was of the same order than with the films polymerised in organic solvents. The UV-Vis characterisation of the films showed that the average conjugation length of the polymer chains was affected only slightly by selecting water as the electrosynthesis medium. Furthermore, FTIR measurements indicated that no ring opening or overoxidation of the films had occurred in either media.
