Abstract:
We have exfoliated graphite in water to give dispersions of mono and few-layer
graphene stabilised 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 DC conductivity of up to 1.5´104 S/m. The
conductivity is stable under flexing for at least 2000 cycles. The electrical
properties are limited by disorder and aggregation suggesting future routes for
improvement.
