Design of Shape Memory Hybrid with Water-assisted Healing Function

Self-healing is meant for automatic repairing, so that a piece of damaged material regains its original properties, and consequently its service life time is extended. Ideally, the material should have the capability to sense the damage and subsequently to react by means of repairing accordingly. However, most of the so-called self-healing materials reported so far are essentially a kind of stimulus-assisted healing, in which self-sensing function is missing and an external stimulus is required for healing.
