Self-healing materials represent an innovative class of smart materials engineered with the inherent ability to detect and repair damage autonomously, mimicking the natural healing processes found in biological systems. These materials can restore structural integrity after experiencing mechanical damage, thereby extending service life, enhancing reliability, and reducing maintenance requirements across numerous applications.
The underlying mechanisms involve the detection of damage followed by a response that restores continuity and functionality through various chemical and physical processes. This revolutionary approach to material design shifts from the traditional damage prevention paradigm to damage management, enabling structures that can maintain performance even after experiencing multiple damage events.
