Mechanizmy of Autonomic Repair

To deliver this autonous functiality, research chers have indexered two primary strategies: extrinsic and intrinsic self-healing systems. Each approach has distint providenges, limitations, and ideal application contexts.

Extrinsic Self- Healing Systems

Capsule- Based Healing

This is mecht widely studied approach. It involves dispersing microcapsule (typically 5- 500 µm in diameter) containg a liquid healing agent the coating. It a crack propagates the material, it ruptures the capsules, releasing thee agent via capillary action.

Intrinsic Self- Healing Systems

Reversible Polymer Chemistry

Polymers functionalizazed with dynamic covalent bondens can reversibliy breaks and re- form. A classic example is the Dies- Alder reaction, when a furan-maleimide adduct disociates at elevated temperatures and re- associates upon cooling.
