Synthesis and properties of a novel electroactive poly(aryl ether ketone) bearing pendant aniline tetramer

摘要

A novel poly(aryl ether ketone) bearing pendant aniline tetramers (PAEK-p-AT) is prepared through nucleophilic aromatic polycondensation. Structures are confirmed via nuclear magnetic resonance, Fourier-transform infrared spectra, and X-ray diffraction. The electrochemical activity of PAEK-p-AT is explored by cyclic voltammetry in 1.0 M H _2SO _4 and confirms a surface controlled process. Moreover, the doped PAEK-p-AT shows a high dielectric constant at room temperature during dielectric testing. The electrochromic performance of a PAEK-p-AT film is investigated by spectrochronoamperometry in detail, exhibiting good electrochromic properties with high contrast value, satisfactory coloration efficiency, and moderate switching times. We report the synthesis of a novel poly(aryl ether ketone) bearing pendant aniline tetramer (PAEK-p-AT). This electroactive material shows high dielectric constant at room temperature and excellent electrochromic properties with high contrast value, acceptable coloration efficiency, and moderate switching times.
