Nanomaterials can enhance autogenous healing through various mechanisms:
Nanoparticles: These can be dispersed within the material matrix to increase its reactivity and promote quicker healing of micro-cracks. Nanofibers: These provide structural reinforcement, bridging cracks and reducing the likelihood of their propagation. Nanocapsules: These can encapsulate healing agents that are released when cracks occur, initiating a repair process.
