Intrinsic Self-Healing

Definition

Intrinsic self-healing refers to the inherent ability of certain materials to autonomously repair damage without external intervention. This characteristic is crucial for synthetic self-healing materials, as it enables them to maintain structural integrity and functionality over time, even after sustaining damage. Understanding intrinsic self-healing mechanisms allows for the development of advanced materials that can enhance longevity and reduce maintenance costs.
