Self-healing and shape-memory materials have attracted significant attention due to their useful and fascinating functionalities. Self-healing materials autonomously detect and respond appropriately when their integrity and state is breached or compromised. Damages such as reduced load bearing properties (in composites), corrosion resistance, radar signature or protective properties are among those that can be detected, reported and rectified autonomously. Shape-memory materials in principle can aid in self-healing of coatings and composites by bringing together the cracked or deformed segments thereby facilitating the re-bonding. In this work we report the preparation, characterization and evaluation of prototype aerospace grade coatings. It was revealed that including shape-memory materials and ordinary sensor in a coating formulation certain damages can be repaired autonomously thereby extending the service life of the coating/composite materials.
