Graphene is a two-dimensional carbon nanomaterial with a hexagonal honeycomb lattice composed of carbon atoms and sp² hybrid orbitals.
Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery. It is considered a revolutionary material in the future.
The common powder production methods of graphene are mechanical peeling method, redox method, SiC epitaxial growth method, and the thin film production method is chemical vapor deposition (CVD).
