Abstract

The invention relates to a method for preparing a high-specific surface area graphene material by utilizing strong base chemical treatment and belongs to the technical field of preparation of graphene materials. By reacting strong base with carbon at high temperature to further perform chemical treatment on graphene powder obtained through thermal treatment or microwave irradiation, nano-scale micropores are rapidly and massively corroded on the surface of graphene, and the specific surface area is greatly improved. Meanwhile, the graphene can be reduced through high-temperature treatment; therefore, high conductivity of the obtained material is guaranteed.

Description

technical field

[0001] The invention relates to a method for producing graphene materials by chemical treatment, and belongs to the technical field of graphene material preparation. Background technique

[0002] Graphene, English name Graphene, is a two-dimensional lattice structure in which carbon atoms are arranged in a hexagonal manner. As a single-layer carbon-atom planar material, graphene can be obtained by exfoliating graphite materials. Graphene has become the focus of scientific and industrial attention since the graphite crystal film was discovered by scientists at the University of Manchester in 2004. The thickness of graphene is only 0.335 nanometers, which is not only the thinnest among known materials, but also very firm and hard; as a simple substance, it transfers electrons faster than all known conductors and semiconductors at room temperature (graphene Electrons move at 1 / 300 the speed of light). Due to the special atomic structure of graphene, the behav...
