Abstract:


Globally, the maintenance and repair of infrastructure cost billions of dollars and impact the day-to-day life of people. Corrosion of infrastructure and metals used in the manufacture of goods and supplies is a major cause of deterioration in the construction industry. Nanocontainerbased self-healing coatings attract enormous scientific attention as they offer a wide range of applications in conjunction with long-lasting inhibition performance. These coatings prevent the rate of crack progression by releasing active agents from micro/nanocontainers in a controllable manner and heal crack, thereby mitigating corrosion. The potential of such coatings to heal local damage induced by climatic causes or by mechanical damage is a significant contributing factor to their desirability. This review is a comprehensive analysis of nanocontainers used to manufacture self-healing anticorrosive coatings as well as explains their self-healing mechanism. The technique used to develop nanocontainers such as layer-by-layer assembly of layered double hydroxide has been clarified. An attempt has also been made to cover the latest developments in the manufacture of nanocontainermediated self-healing corrosion coatings used in several construction industries.
