  Intrinsic layered structure of graphite is the source of ongoing and
expanding search of ways of obtaining low-cost and promising graphite thin
layers. We report on a novel method of obtaining and separating rubbed graphite
sheets by using water soluble NaCl substrate. The electrical behavior of sheets
was characterized by current-voltage measurements. An in-plane electrical
unisotropy depending on rubbing direction is discovered. Optical microscopy
observations combined with discovered non-linear electrical behavior revealed
that friction leads to the formation of sheet makeup which contain an optically
transparent lamina of self-organized few-layer graphene.
