A Cheaper Method For Graphene Production
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. This method is attractive because it can produce single-layer graphene 85% of the time without dangerous chemicals or expensive solvents.
