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...
