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 up to 1.5 x 10(4) S m(-1). 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.

TLDR
Methods to disperse and partially size separate NbSe(3) nanowires in aqueous surfactant solutions can easily be formed into thin films, and films thinner than ∼ 70 nm displayed reduced DC conductivity due to percolative effects.
