An anticorrosion layer of a smart polymer coating is developed. The nature and properties of the coating simultaneously provide three mechanisms of corrosion protection: passivation of the metal degradation by controlled release of an inhibitor, buffering of pH changes at the corrosive area by polyelectrolyte layers, and self‐curing of the film defects due to the mobility of the polyelectrolyte constituents in the layer‐by‐layer assembly.
