Self healing nature of bilayer graphene

Electrical and Thermal and Self-Healing Properties of Graphene-Thermopolyurethane Flexible Conductive Films

“…In theory, they can realize multiple self-healing of the damaged materials with the assistance of external light, heat, and electric field, et al Although, great progress has been made in the research of the self-healing materials and techniques, there are still some critical problems that restrict their applications, such as low mechanical properties after healing, high cost, time-consuming, and low efficiency. Therefore, it is significant to fabricate a self-healing polymer and composites based on new materials, and then explore their potential applications, as well as new healing method.Graphene (G), a novel two-dimensional material, possesses large specific surface area, superior mechanical property, as well as being an excellent conductor of both heat and electricity, and having a good microwave and infrared absorbing capacity, so they have strong response to electricity and electromagnetic waves and infrared radiation (IR) [30][31][32][33][34]. Graphene is often used as fillers in preparing functional composites.…”

“…Oh et al synthesized thermally self-healable graphene nanoplate-PU composites using in-situ Diels-Alder (DA) reaction of graphene nanoplate and furfuryl derivative as a chain extender of PU prepolymers [7]. Previous studies demonstrated that appropriate polymers, containing graphene, might develop some self-healable materials [30][31][32][33][34][35][36].Most of the previous research work, relating to the polymer composites containing graphene, mainly focus on improving the mechanical property and self-healed performance by near IR light [5,6,[30][31][32][33][34][35]. To the best of our knowledge, there are few reports that systemically investigate graphene-polymer composites as self-healing flexible conductive film.…”
