Abstract

The invention relates to a graphite chemical substance intercalation reaction vessel and a technological method thereof. The reaction vessel comprises a reaction vessel body (1), a mixer shaft (5) is arranged on the central part of the reaction vessel body (1) along the vertical direction, two spiral stirring vanes (6) are arranged on the mixer shaft (5), the two spiral stirring vanes (6) symmetrically wind around the mixer shaft (5) in a spiral mode, spiral directions of the two spiral stirring vanes (6) are opposite, a support (7) is arranged between the two spiral stirring vanes (6), multi-strip elastic racks (9) are uniformly arranged on an inner wall of the reaction vessel body (1), and a supersonic generator (13) is arranged at the bottom of the reaction vessel body (1). The invention provides the graphite chemical substance intercalation reaction vessel and the technological method thereof, pollution by harmful gas such as SOx and NOx or heavy metal ions cannot be generated during a production process, sulfur residue does not exist in the product, oxidation resistance is good, defect of graphene is not generated easily, and final product quality can be effectively guaranteed.

Description

technical field [0001] The invention relates to a preparation method of graphene, in particular to a graphite chemical substance intercalation reaction kettle in the graphene production process and a process method thereof, belonging to the technical field of material science. Background technique [0002] Graphene is a single-atom-thick layer of carbon atoms, a two-dimensional carbon atomic crystal that has only been discovered in recent years. ), because of its special mechanical, quantum and electrical properties, it has attracted much attention in the field of physics and materials science. The two-dimensional crystal structure of the free state has long been considered to be thermodynamically unstable and cannot exist independently in ordinary environments. In 2004, Geim et al. of the University of Manchester peeled off a small amount of graphene monoliths from graphite and studied its electrical properties. They found that it has special electronic properties and has ...
