Facile strategy toward the development of a self-healing coating by electrospray method

A self-healing anti-corrosion epoxy coating was prepared by the incorporation of dual capsule healing system.Microcapsules were prepared through the facile electrospray MDI based isocyanate respectively).Electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization technique were used to assess the effects of utilizing the aforementioned system on the intrinsic anti-corrosion barrier property (on pristine samples ) and the self-healing efficiency (after cross scratching) of the resulting smart coatings.The corrosion assessment results confirmed the self-healing performance of the incorporated capsules along with a high healing efficiency (85%) for the optimum microcapsule content.
