N2 - The comparison of different suspensions, obtained from the same material source subjected to electrochemical exfoliation and to analogous auxiliary treatments, but in different solutions, allowed choosing the most effective approach to obtaining graphene suspensions.

The most important parameter determining the mobility of carriers in the films obtained from suspensions is found to be the flake thickness. The carrier mobility strongly decreased from ∼100 to 0.05 cm2/V·s when the flake thickness changed from one monolayer to few monolayers (up to ∼ 4–5 nm).
