Nanostructure expanded graphite

Graphene is actually the single 2-D layer of graphite with one-atom-thick, sp -bonded honeycomb carbon lattice. This material was first isolated from graphite by exfoliation with adhesive tape in 2004 and fabrication methods of graphene have expanded quickly since then. Graphene and its derivatives are such new carbon nanostructures that their research and applications in orthopedics are still limited. Here, their fabrication methods are briefly overviewed and the readers can refer to literature [40] for more details.
