Extraction process based on novel graphene material

Abstract

The invention discloses an extraction process based on a novel graphene material. A device used in the extraction process comprises an extraction box, wherein the center of the interior of the extraction box is rotatably connected with a separation barrel, and the left side of the top of the extraction box is provided with a material supplementing port. The invention relates to the technical field of graphene processing. According to the extraction process based on the novel graphene material, by arranging a water circulation structure, stripping liquid can circularly flow, and then the stripping liquid can better make contact with graphene flakes; meanwhile, the separation barrel containing the graphene flakes can be indirectly pushed to rotate by means of the pushing force of water circulation, the graphene flakes in the separation barrel can fully roll over through cooperation between the pushing force of water circulation with the pushing force of water flow, so stripping effect is better; and no extra stirring device needs to be arranged, a material blocking structure is arranged in the separation barrel and can block a part of turned graphene flakes, then the situation that the whole graphene flakes completely rotate along with water flow can be avoided, the graphene flakes make full contact with stripping liquid, and better effect is obtained compared with an existing stirring structure.

Description

technical field [0001] The invention relates to the technical field of graphene processing, in particular to an extraction process based on a new graphene material. Background technique [0002] Graphene is a new material in which carbon atoms connected by sp2 hybridization are closely packed into a single-layer two-dimensional honeycomb lattice structure. Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery, and is considered to be a revolutionary material in the future. Graphene is one of the materials with the highest strength known, and it also has good toughness and can be bent. The theoretical Young's modulus of graphene reaches 1.0TPa, and its inherent tensile strength is 130GPa. The reduced graphene modified by hydrogen plasma also has very good strength, and the average modulus can be greater than 0.25TPa. Graphite paper com...
