Description

technical field [0001] The invention belongs to the technical field of graphene preparation, and more particularly, relates to a continuous production device and method of aminated graphene. Background technique [0002] Graphene is a carbon atom with sp 2 The hybrid orbitals form a hexagonal flat film with a honeycomb lattice, with a thickness of one carbon atomic layer (0.35 nm), which has excellent mechanical, electrical and thermal properties. At present, graphene is widely used in the composite modification of materials. Using the excellent properties of graphene to modify the matrix material can significantly improve the performance of the matrix material. Therefore, graphene nanocomposites have become a hot research topic in the material field. [0003] In order to ensure the interface between graphene and the matrix material, the surface of graphene needs to be modified by small molecules to achieve the purpose of introducing groups on the surface of graphene. For e...
