A novel electroactive poly(aryl ether ketone), with fixed conjugated length of oligoaniline(phenyl-capped aniline tetramer) in the main chain, was successfully synthesized via oxidative coupling polymerization method. The structure of poly(aryl ether ketone) was systematically studied by Fourier-transform infrared( FTIR) spectra, 1H NMR, and X-ray powder diffraction(XRD). And its electrochemical behavior was studied by cyclic voltammetry(CV) measurement. It was found that the obtained poly(aryl ether ketone) bearing phenyl-capped aniline tetramer segments had a reversible electrochemical property in the cyclic voltammetry, which was the same as that of polyaniline. Moreover, the thermal properties of poly(aryl ether ketone) were evaluated by thermogravimetric analysis(TGA).
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.
