Zusammenfassung:Interpenetrating microvascular networks are embedded in an epoxy substrate via direct‐write assembly. Each network is filled with one component of a two‐part epoxy resin. This novel epoxy coating/substrate architecture enables repeated healing of at least 30 cycles of mechanical damage in the coating by independently supplying both healing agents to the damaged region(s).
