WebMar 22, 2024 · In the case of graphene, when the ions hit the surface at a high temperature, single layers of graphene are separated from the 3-D graphite structure. A centrifuge, which spins samples quickly to separate them based on density, can then be used to separate the remaining graphite from the graphene produced and ensure high purity.
