Abstract

The invention discloses a device and method for preparing graphene. The device comprises a base, wherein a reaction device is arranged at the top of the base, the reaction device comprises a first supporting rod, the first supporting rod is fixedly connected with the base, a first motor is arranged at the top of the first supporting rod, a first rotary shaft is arranged on one side of the first motor, an output shaft of the first motor is fixedly connected with the first rotary shaft, a reaction box is arranged on one side of the first rotary shaft, the first rotary shaft penetrates through the reaction box and extends into the reaction box, a spiral blade is arranged on the outer side of the first rotary shaft, and a stirring plate is arranged on one side of the spiral blade. By arrangingthe reaction device, the first motor drives the spiral blade to rotate reversely, so that a graphite raw material is evenly distributed in the reaction box, meanwhile, the graphite raw material is heated by a heater, the reaction efficiency is advantageously improved, the graphite raw material is dispersed through leaking holes in the surface of the spiral blade, and meanwhile the stirring platestirs the graphite raw material to a position above the reaction box.

Description

technical field [0001] The invention relates to the technical field of graphene preparation and application, in particular to a device and method for preparing graphene. Background technique [0002] Graphene is a carbon atom with SP 2 The hybrid orbitals form a hexagonal two-dimensional carbon nanomaterial with a honeycomb lattice. 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. Andre Geim and Konstantin Novoselov, physicists at the University of Manchester in the United Kingdom, successfully separated graphene from graphite by micromechanical exfoliation, so they jointly won the 2010 Nobel Prize in Physics. The common powder production methods of graphene are mechanical exfoliation method, redox method, SIC epitaxial growth method, and the thin film production me...
