Self-healing materials are innovative substances designed to automatically repair damage without human intervention. These materials can recover from scratches, cracks, or other forms of wear, extending their lifespan and reducing maintenance costs. They are often used in applications like coatings, electronics, and structural components. The technology behind self-healing materials typically involves embedded microcapsules or networks that release healing agents when damaged. This process mimics natural healing found in biological systems, such as the way skin repairs itself. Researchers are exploring various types of self-healing materials, including polymers and composites, to enhance their effectiveness and applications in industries like aerospace and automotive.
