Self-healing coatings inspired by biological systems possess the ability to repair physical damage or recover functional performance with minimal or no intervention. A new article provides a comprehensive and updated review on the advantages and limitations associated with common autonomous and non-autonomous self-healing mechanisms in protective organic coatings used for anti-corrosion purposes.

Autonomous and non-autonomous self-healing mechanisms

The autonomous healing mechanisms are often enabled by embedding polymerisable healing agents or corrosion inhibitors in the coating matrices. For non-autonomous mechanisms, the healing effects are induced by external heat or light stimuli, which trigger the chemical reactions or physical transitions necessary for bond formation or molecular chain movement.

The study is published in: Corrosion Science Volume 144, November 2018, Pages 74-88.

Event tip

If you want to learn how corrosion occurs, what types of corrosion are out there and how coatings can prevent it, you should visit the European Coatings Seminar Anticorrosive Coatings in November 2018.
