Electrochemical Synthesis, Characterization and Electrochemical behaviour of New Conducting Copolymer of 2-methoxyaniline-co-2,3-dihydrothieno[3,4-b][1,4]dioxine-2-carboxylic acid

Abstract

Electroactive conducting copolymers of 2-methoxyaniline  and ??2,3-dihydrothieno[3,4-b][1,4]dioxine-2-carboxylic acid (EDOT carboxylic acid) molecules were prepared in ?non-aqueous solution by electrode potential cycling. Copolymerization was carried out at different feed ?concentrations of the monomers on a gold electrode. Four different feed concentrations were used to prepare ?four different copolymers. The obtained copolymers were characterized with cyclic voltammetry and ?infrared spectroscopy. The prepared hompolymers and copolymers were investigated with in situ ?conductivity measurements. Two transitions were observed in the in situ conductivities of the copolymers.
