Self-healing coatings have been promising due to its automatic recovering functions that can improve the anticorrosive property. A general approach to a self-healing coating is to encapsulate the healing agent into core-shell microcapsules which integrate into the coating matrix. In this study, linseed oil will be chosen as a healing agent and encapsulated in poly(urea-formaldehyde) (PUF) shell via in-situ polymerization. Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA) will be used to characterize the chemical composition of the synthesized microcapsules. The size and morphology of the synthesized microcapsules will be characterized by an optical microscope and scanning electron microscope (SEM). The microcapsules will be integrated into epoxy coating matrix to fabricate the self-healing coating. Electrochemical impedance spectroscopy (EIS) will be used to monitor the anti-corrosion performance of the self-healing coating. Mechanical properties such as adhesion of the self-healing coating will also be evaluated.
