Self-healing coatings for inhibiting corrosion of ferrous metals exposed to preservative-treated bamboo

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 char-acterization of microcapsules were first described. The characterization included the particle size, surface morphol-ogy, 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
