Description
Summary:This study aims to provide an effective method of inhibiting the corrosion of ferrous metals exposed to preservative-treated bamboo, thereby prolonging material service life and reducing maintenance costs. The synthesis and characterization of microcapsules were first described. The characterization included the particle size, surface morphology, thermal stability, and core content of microcapsules. The results showed that microcapsules had good thermal stability and high core loading. Then, the self-healing performance and corrosion resistance of self-healing coatings were evaluated. The results indicated that self-healing coatings can identify and heal the damage automatically and had a more positive effect on inhibiting metal corrosion. Also, the mechanical properties of self-healing coatings were analyzed. The results demonstrated that microcapsule embedment did not almost affect the mechanical properties of self-healing coatings.
