Self-healing polymers are synthetic or artificially-created substances that have built-in ability to automatically repair damages to themselves without any external diagnosis of the problem or human intervention. Generally, materials will degrade over time due to damage incurred during operation, environmental conditions or fatigue.

Cracks and other types of damage on macro- and microscopic levels have been shown to change acoustical, electrical and thermal properties of polymers, and the propagation of cracks can lead to the eventual failure of the material.

In general, cracks are hard to detect at an early stage, and manual intervention is required for periodic repairs and inspections. In contrast, self-healing polymers counter degradation through the initiation of a repair mechanism that responds to the microdamage.

Some self-healing polymers are classed as smart structures and can adapt to various environmental conditions according to their sensing and actuation properties. Although the most common types of self-healing materials are elastomers or polymers, self-healing covers all classes of materials, including cementitious substances, ceramics, and metals.
