The self-healing process in catalytic materials can be triggered by various mechanisms. Some of the prominent methods include:
1. Microcapsules: These contain healing agents that are released upon damage, subsequently filling cracks or voids. 2. Shape Memory Polymers (SMPs): These materials can return to their original shape when exposed to a stimulus such as heat. 3. Intrinsic Healing: This involves the reformation of broken bonds within the material itself, often facilitated by dynamic covalent bonds or reversible cross-links. 4. Nanoparticle Migration: In some catalytic materials, nanoparticles can migrate to damaged areas and restore functionality.
