Corrosion control has been an important topic in industries and research sectors for many years. A number of control methods have been employed and are being developed to provide an ultimate solution for protecting metals from corrosion. The inefficiency of the conventional methods led to the discovery of smart coatings. Of these smart coatings, the self-healing coatings with containers prove to be assuring and impressive. The possibilities of fabricating the containers to suit the purpose are endless. They can be loaded with chemicals/corrosion inhibitors/healing agents or encapsulated by layers of different materials or designed and synthesized to have end stoppers. However, more research and development is done in this area to shape up a better container-based self-healing coating that can be autonomous, function effective, be cost-effective, and be manufacturable at large scale of production. This chapter focuses on the current trend prevailing in self-healing coatings with polymer, mesoporous silica, and halloysite nanotubes. © 2020 Elsevier Inc. All rights reserved.
