Graphene-based material for self-healing: mechanism, synthesis, characteristics, and applications

The intelligent material having the capability to repair after some external damage and restore its original properties is known as self-healing material. So these materials have the extended life span and are cost-effective for various advance applications such as photocatalytic, solar cell, and flexible electronics. However, the mechanical, physical, and chemical properties of these materials after self-healing depend on the healing mechanism and its various pathways such as heating process, application of mechanical force, electromagnetic wave’s interaction, moisture control, electricity, catalyst approach, oxidation, reduction, and bionic process. The properties of self-healed material can further enhance through the incorporation of graphene because of its extraordinary properties. Therefore various efforts, dedicated on the research of graphene-based self-healing materials, are being raised every year. In this chapter, the concise review of graphene-based self-healing materials and their main synthesis approach, mechanism, various pathways, advanced applications have been reviewed.
