The autonomic healing concept A microencapsulated healing agent is embedded in a structural composite matrix containing a catalyst capable of polymerizing the healing agent.  a) Cracks form in the matrix wherever damage occurs.  b) The crack ruptures the microcapsules, releasing the healing agent into the crack plane through capillary action.  c) The healing agent contacts the catalyst, triggering polymerization that bonds the crack faces closed.   Cracks in a brittle coating are healed autonomously via a three-dimensional microvascular network embedded in the underlying substrate. The network contains a healing agent (red) which polymerizes after contacting the catalyst (purple) in the damaged regions. Self-healing coating specimens consist of a microvascular network in the substrate containing the fluid healing agent and a brittle coating on top containing catalyst.

  The microvascular self-healing concept consists of an embedded microvascular network containing a fluid healing agent and dispersed catalyst particles. Crack damage intersects the network, allowing healing agent to fill the crack and react with the catalyst. Healing is repeatable due to the vascular nature of the healing agent supply. |
