Self-healing Polymer Coatings in Corrosive Environments

摘要

Polymer coatings are commonly applied to metal substrates to prevent corrosion in corrosive environments such as high humidity and salt water. Once the polymer coating has been breached, for example due to cracking or scratches, it loses its effectiveness, and corrosion can rapidly propagate across the substrate. In our presentation, we will demonstrate self-healing polymer coatings based on the dispersion of healing agents and microencapsulated catalysts in the polymer coating.
