Synthesis and properties of a poly(pyrrole)-poly(phenylene oxide) electroconducting film

The poly(pyrrole)-poly(phenylene oxide) electroconducting film was obtained by modification of poly(phenylene oxide) via a series of successive chemical transformations, including sulfonation of poly(phenylene oxide), its activation, and polymerization of pyrrole. The products of chemical transformations were studied by thermal analysis. Evolution of the electrical properties of poly(phenylene oxide) during modification was investigated, and it was found that the end product in the doped state is a highly conductive system. As demonstrated by the gas-diffusion experiments, the electrocoducting film is formed as a continuous layer on the surface of polymer articles.
