A new type of epoxy–polyelectrolyte anticorrosion protective material based on epoxy resin, ion-exchange resin, and polyaniline has been studied. Electrical-percolation transitions are observed after submerging stainless-steel plates coated with epoxy–polyelectrolyte compositions in a solution of NaCl. Conductivity data processed within a percolation model show that the modification of ion-exchange resin by polyaniline strongly influences the coating model parameters owing to changes in physicochemical and morphological properties of ion-exchange resin. It is established that the electrochemical response to the action of an aqueous salt solution can be controlled by variation of the material composition.
