Application of an effective self-healing coating on copper surface

The self-healing coating consisting of healing and anti-corrosion agents was prepared and its performance on the copper filmswas investigated. The fourier-transform infrared spectroscopy (FTIR) and field emission scanning electron microscopy (FESEM) techniques were applied for chemical structure and surface morphology investigations respectively. The anti-corrosion effect and self-healing process of the coatings was studied by electrochemical impedance spectroscopy (EIS) and FESEM respectively. Taguchi method was used to design the experiments and anti-corrosion efficiency evaluations. The diameter of synthesized nanocapsules was about 459–712 nm. The obtained loading efficiency was about 60%. Coatings containing self-healing and anti-corrosion agents together showed the best result.
