title: Direct exfoliation of graphite to graphene by a facile chemical approach.
abstract: Facile exfoliation of graphite: High-quality graphene sheets are produced directly from graphite by a facile chemical approach. The new strategy for non-oxidized chemical exfoliation of graphite is based on a pre-intercalated process with oleum and a further strong reaction with sodium in the graphite layers under grinding conditions. This method is facile, low cost, and high throughput.
