Abstract Self-healing materials attract enormous scientific attention as they offer wide range of applications in conjunction with long-lasting performance. Self-healable polymers find potential candidates for construction materials, automotive parts, electrical encapsulation, adhesives, coatings, etc. Due to the lightweight, high thermo-mechanical performance, excellent adhesion, gloss, good chemical resistance, and corrosion resistance, epoxy resins are preferred over other polymers for coating applications. Although epoxy resin coatings are widely used in commercial vehicles and high compact aircraft, their susceptibility toward scratches and microcracks is a major concern. Such failures may be addressed by making use of self-healing epoxy coatings. In this review, we focus on inhibitor and polymeric healing agents encapsulated in organic and inorganic containers for the self-healing epoxy coating. The different organic and inorganic containers such as micro/nano polymer capsules, cellulose nanofibers, halloysite nanotubes, titanium dioxide nanocontainers, mesoporous silica, hollow glass fibers, and core–shell nanofibers have been utilized as reservoirs to store the self-healing agents. In addition, self-healing techniques such as layer-by-layer method, microvascular networks, ion exchange method, reversible crosslinks, and shape memory assisted self-healing are reviewed.
