| titleOfInvention | Graphene/polymer self-repairing material and preparation method thereof |
| abstract | The invention relates to a graphene/polymer self-repairing material and a preparation method thereof. In the self-repairing material, the functionalized graphene, the functionalized polymer and the cross-linking agent form a reversible cross-linking network through a reversible Diels-Alder reaction (DA reaction), so that the composite material has excellent self-repairing performance. The preparation method comprises the steps of reacting graphene oxide with furfuryl amine to obtain furan functionalized graphene, copolymerizing furfuryl methacrylate with other methacrylates to obtain furan functionalized polymethacrylate, compounding the furan functionalized graphene with the furan functionalized polymethacrylate, and adding a cross-linking agent bismaleimide to obtain the graphene/polymer composite material with excellent self-repairing performance. Compared with the prior art, the raw materials involved in the invention are low in price and mild in reaction conditions, and the obtained graphene/polymer composite material has excellent mechanical properties and high-temperature self-repairing properties, so that the service life of the material is greatly prolonged. The preparation method is simple, convenient to operate and high in practicability. |
