2022 4 1 Graphene / ˈ ɡ r æ f iː n / is an allotrope of carbon consisting of a single layer of atoms arranged in a two dimensional honeycomb lattice nanostructure. The name is derived from graphite and the suffix ene reflecting the fact that the graphite allotrope of carbon contains numerous double bonds.. Each atom in a graphene sheet is connected to its three nearest

The ball milling of graphite and MWCNTs with liquid additives reduced the agglomeration of MWCNT and transformed graphite to graphenes. The ball milling of MWCNTs under impact mode usually resulted in the formation of an amorphous phase whereas that under friction mode induced the fattening of nanotubes.
