Abstract

Conduction properties and intermolecular interactions in systems based on high-molecular-weight sulfonic acids (poly(4-styrenesulfonic), poly(2-acrylamidomethylpropane-sulfonic), and perfluorosulfonic (MF-4SC)) and polyaniline were studied by impedance and IR spectroscopy. In all systems, an interpolyelectrolyte complex is formed due to strong hydrogen bonding. In two former cases, the interpolyelectrolyte complexes form nanodispersed powders with ionic and electronic conductivity. MF-4SC—polyaniline solutions were used for the membranes preparation with high ionic conductivity.
