【 摘 要 】

Composites that owns healing property has acquired wide range of application especially in coatings. Microcapsules embedded coatings provide both damage protection and damage management imposing itself among the sophisticated applications. Although the microcapsules coatings have spectacular aspect, their effect on coating properties still under study due the broad properties variation of microcapsules. In this work, PMMA microcapsules filled with Bisphenol-A epoxy is incorporated into epoxy coating. The coating is self-healing and can be used for anti-corrosion applications. The properties of the prepared coating were investigated via scratch test and through microhardness test and the healing process is monitored through optical microscope. The investigation shows that embedding microcapsules into epoxy matrix will achieve both in self-healing coating and better performance.
