Synthesis and Structure Characterization of a Novel Electroactive Polyamide via Oxidative Coupling Polymerization

By oxidative coupling polymerization a novel electroactive polyamide, with fixed conjugated length of oligoaniline(amine-capped aniline pentamer) in the main chain, was successfully synthesized. The structure of the electroactive polyamide was confirmed via FTIR and NMR. The UV-Vis spectra were used to monitor the chemical oxidation process of the reduced polyamide. Moreove, its electrochemical behavior was investigated by cyclic voltammetry(CV) measurement. It was found that the obtained electroactive polyamide with amine-capped aniline pentamer segments had a quasi-reversible electrochemical property in the cyclic voltammetry, which was the same as polyaniline. Its electrical conductivity is about 1.24×10-6 S/cm at room temperature upon preliminarily protonic-doped experiment.
