Electroactive Azo Polyamide Based Oligoaniline: Synthesis and Characterization

An alternating copolymer, electroactive azo polyamide was prepared by oxidative coupling polymerization of oligoaniline macromonomer and p-phenylenediamine. The molecular structure of the polyamide was characterized by Fourier-transform infrared (FT/IR) spectra, 1 H NMR spectroscopy, elemental analysis (EA) and gel permeation chromatography (GPC). UV-vis spectrum was used to monitor the chemical oxidation process and the photoisomerization of the polymer. The electrochemical activity of the polyamide was checked by cyclic voltammetry (CV) and the mechanism of electrochemical oxidation process was well studied. Moreover, the thermal characteristics of the polyamide were evaluated by thermogravimetric analysis (TGA).
