Researchers at the University of Queensland have developed a self-repairing coating designed to extend the lifespan of rust protection on steel. The technology uses water-based paint embedded with nanocontainers that encapsulate the inhibitor Benzotriazole. These particles respond to acidity changes to automatically patch cracks, potentially slowing rusting by more than 600 times compared to current high-performance coatings.

In addition to these smart coatings, industrial developments include the production of Magnelis by ArcelorMittal. This metallic coating, composed of zinc, aluminum, and magnesium, is designed for extreme climates and aims to provide protection three times superior to conventional galvanized steel while reducing zinc requirements and maintenance needs.
