Abstract
Self-healing coatings are intended to increase long-term durability and reliability and can be prepared by the use of microcapsules containing a self-healing agent capable of interacting with the matrix and regenerating the system. This review article provides an overview of the stateof- the-art patents published in the field of microcapsule-based self-healing organic coatings since the early 2000s. A discussion regarding coatings for corrosion protection is presented and the different self-healing approaches and mechanisms are also addressed, as well as future challenges and expectations for this kind of coatings.
Keywords: Coatings, self-healing, microcapsules, anti-corrosion, polymer, patents.
