In this work a capsule-type self-healing protective coating has been developed using vegetable oils as healing agent. Healing-agent-loaded microcapsules are embedded in a coating matrix to obtain a self-healing protective coating. Upon damage-induced cracking, the microcapsules are ruptured by the propagating crack fronts, resulting in release of the healing agent into the crack by capillary action. A healing reaction occurs by atmospheric oxygen, generating a gel or highly viscous liquid. The self-healing coating was evaluated as protective coating for steel, and it was demonstrated that our system has good self-healing capability. |
