Abstract
In this paper we present the transmission electron microscopy characterization of the graphene membranes produced by exfoliation of KC 8 in N-methyl-pyrrolidone. This approach allows processing of large quantities of material, with a yield of 35% of the starting graphite, producing large, micron size, membranes composed of only few graphenes. The characterization of the solutions reveals the crumpled folded structure of the graphene membranes and their stacking structure.
