N2 - Self-healing polymers can be expected to contribute to the extension of polymer lifetime, reduction of waste, and the development of reliable restorative materials. The idea of self-healing polymers was spotlighted as accessible materials by a pioneering work in the beginning of this century. The work employed the encapsulation of a "healing agent" (in this case, a bifunctional monomer) that would be released after a crack in the polymer breached the microcapsules, and subsequently the agent polymerized after contact with an initiator or catalyst embedded within the polymer matrix. Since this seminal work, plenty of self-healing materials have been reported and some are now available commercially. More strategies toward the development of self-healing polymers have been proposed. Both physical and chemical strategies have been explored, with the latter further classified into three separate branches, making use of healing agents, non-covalent interactions, and reversible covalent bonds.
