Research output: Contribution to journalArticlepeer-review


Interpenetrating microwascular 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).
