[0002] Graphene is a two-dimensional carbon nanomaterial composed of a single layer of carbon atoms in sp2 hybrid orbitals, with excellent properties such as high strength, high electrical conductivity, and high thermal conductivity. Polymer materials are materials made up of a large number of identical or different chemical units repeatedly connected, with good processability, plasticity, and certain strength and durability. Graphene-modified polymer materials combine graphene with polymer materials in some way, and use the excellent properties of graphene to modify polymer materials, thereby obtaining composite materials with new properties or enhanced properties. This modified material combines the advantages of graphene and polymer materials and can be applied in many fields.
