Electrochemical synthesis and structural studies of polypyrroles, poly(3,4-ethylene- dioxythiophene)s and copolymers of pyrrole and 3,4-ethylenedioxythiophene on carbon fibre microelectrodes

摘要: Polypyrrole, poly(3,4-ethylenedioxythiophene) and the copolymer of pyrrole 3,4-ethylenedioxythiophene films were synthesized electrochemically on carbon fibre microelectrodes (CFME). Deposition conditions influence monomer concentrations copolymerization, as well electrochemistry resulting polymers copolymers, studied. Structural studies conducted using different techniques such cyclic voltammetry, in situ spectroelectrochemistry, FTIR scanning electron microscopy. The effect ratio formation is reported. A high level stability to overoxidation was also observed for polymer this CFME substrate shows limited degradation its electroactivity at potentials 1.2 V above half-wave potential.
