摘要: A simple and effective strategy is proposed to vane the number of graphene layers by selecting suitable starting graphite, using a chemical exfoliation method. It is found that both the lateral size and the crystallinity of the starting graphite play important roles in the number of graphene layers obtained. Using artificial graphite, flake graphite powder, Kish graphite, and natural flake graphite as starting materials, similar to 80% of the final products are single-layer, single- and double-layer, double- and triple-layer, and few-layer (4-10 layers) graphene, respectively, while a mixture of few-layer (4-10 layers) and thick graphene (>10 layers) is obtained when highly-oriented pyrolytic graphite is used. The smaller the lateral size and the lower the crystallinity of the starting graphite, the fewer the number of graphene layers obtained. Moreover, the graphenes obtained are of high-quality with an electrical conductivity of similar to 1 x 10(3) S/cm. These findings open up the possibility for controlled production of high-quality graphene with a selected number of layers in a large quantity. (C) 2008 Elsevier Ltd. All rights reserved.
