摘要：

Graphite is exfoliated in water to give dispersions of mono- and few-layer graphene stabilized by surfactant These dispersions can be used to form thin, disordered films of randomly stacked, oxide-free, few-layer graphenes. These films are transparent with a direct current conductivity of tip to 1.5 x 10(4) S m(-1). The conditctivity is stable tinder flexing for at least 2000 cycles. The electrical properties are limited by disorder and aggregation suggesting future routes for improvement.
