Special nanocontainers, micro- and nanocapsules can be incorporated in an anticorrosive primer formulation to provide self-healing properties that take effect as soon as the primer is mechanically damaged. As the matrix continuity and the interfaces are affected, we cannot fully evaluate the performance of such ‘self-healing’ primers by eye. Electrochemical impedance spectroscopy (EIS) combined with thermocyclic electrolytic loading (TEL) contributes significantly to evaluating such systems.
