Oxidative chemical copolymerization of pyrrole(Py) and aniline (An) by copper perchlorate in acetonitrile was carried out. By varying the monomer feed ratios, the copolymer compositions could be effectively modified. The high-resolution X-ray photoelectron spectroscopy (XPS) analysis using monochromatized Al Kα X-ray source enabled the quantification of the proportions of pyrrole and aniline units...
