One-Part Self-Healing Anticorrosive Coatings

Corrosion control is one of the most important issues in the fields of materials design and application, and the concept of self-healing has been recently proposed as a novel approach to achieve corrosion protection function. Although extensive investigation has been made to self-healing materials, one-part self-healing anticorrosive coatings is a relatively new topic. In the present work, the background of one-part self-healing anticorrosive coatings is presented and the strategy for their design discussed. The one-part self-healing anticorrosive coating is further demonstrated by two examples, that is, diisocyanated-based and organic silane-based coatings. One-part self-healing anticorrosive coatings are fabricated through the microencapsulation of different healing species, and good self-healing anticorrosive performance of the prepared coatings is characterized by different methods.
