Definition and Principles of Operation
Self-healing materials can be defined as substances that are capable of self-repair after mechanical, chemical, or thermal damage. The principles of operation of such materials are based on the use of various mechanisms, such as:
Polymer matrices: Include microcapsules with healing agents that are released upon damage.
Network structures: Used to create new bonds at the site of damage.
Phase transition: The change of the material's state under certain conditions, which promotes the restoration of its properties.
Types of Smart Materials
Among the existing classes of smart materials, several main categories stand out:
Polymeric self-healing materials: Used in construction and furniture manufacturing. Their ability to restore shape and density makes them ideal for various tasks.
Metallic alloys: Research is ongoing for their use in aviation and the automotive industry. Resistance to corrosion and mechanical damage allows for an extended service life of products.
Ceramics: Have high strength and thermal stability. Self-healing ceramic materials open new possibilities in high-tech fields.
