Abstract
A self-healing capsule may contain a self-healing agent, a polymer shell encapsulating the self-healing agent, and at least one functional group orthogonal to the surface of the polymer shell. This self-healing capsule may be covalently bonded into a polymeric material by the orthogonal functional group. The self-healing capsules may be formed through microencapsulation.
