Description

technical field [0001] The invention belongs to the technical field of graphene composite materials, and in particular relates to a graphene nanocomposite material and a preparation method thereof. Background technique [0002] Graphene is a new type of carbonaceous material in which a single layer of carbon atoms is arranged in a two-dimensional honeycomb lattice structure. It is considered to be the basic unit of all other dimensional carbonaceous materials, such as fullerenes that can be packed into zero dimensions. , rolled into one-dimensional carbon nanotubes, stacked into three-dimensional graphite, etc. Graphene is made of carbon atoms with sp 2 The monoatomic carbon layer formed by hybridization has a very stable structure and has excellent mechanical properties, peculiar electrical properties and good thermal properties. However, when preparing graphene nanocomposites, due to the superhydrophobicity of the graphene surface and the inherent van der Waals force bet...
