Schematic representing nano- and microcapsule-based self-healing approach: a Nano/microcapsule core-shell structure, the core contains healing agent(s) or catalyst; b Triggered release of healing agent(s) by crack; c Crack healing mechanism, microcapsule shell is ruptured by damage and releases healing agent(s) to damage site. The reaction occurs upon contact of encapsulated healing agent A with B; the crack is then filled and healed.
