Soluble and highly ionically conducting interpolyelectrolyte complexes prepared via chemical template polymerization of aniline in the presence of perfluorinated polysulfonic acid

Abstract

Chemical polymerization of aniline in the presence of MF-4SC, a perfluorinated polysulfonic acid, is carried out for the first time in the mixed solvent water/2-propanol. The polymerization results in soluble interpolyelectrolyte complexes forming free-standing films with high proton conductivity, up to 0.05 S cm⁻¹, and electrical conductivity of 6 × 10⁻⁵ S cm⁻¹.
