Precursor monomer route: A novel concept for producing highly conductive polypyrrole films

Abstract Heating of micro porous UHMW-PE films, impregnated with a solution of pyrrole-2-carboxylic acid and FeCl 3 , results in tough and flexible films with conductivities up to 10 S/cm. Within the films a continuous network of polypyrrole is present as a coating layer on the micro fibrils of polyethylene. By triggering of the reaction via thermochemical, oxidative decarboxylation of the pyrrole-2-carboxylic precursors, a controlled and efficient polymerisation is provided, resulting in a fast and continuous production process.
