How is graphene made from graphite
WebThe mechanism behind LPE is based on the fact that graphite is a layered material and essentially can be seen as individual graphene crystals stacked one on top of each other. The LPE process involves milling … WebDispersing graphite in a proper liquid medium can produce graphene by sonication in a process known as Liquid Phase Exfoliation. Graphene is separated from graphite by centrifugation, [16] producing graphene concentrations initially up to 0.01 mg/ml in N-methylpyrrolidone (NMP) and later to 2.1 mg/ml in NMP,. [17]
