Coarse grained models of graphene and graphene oxide for use in aqueous solution

Obtaining stable aqueous dispersions of graphene-based materials is a major obstacle in the development and widespread use of graphene in nanotechnology. The efficacy of atomistic simulations in obtaining a molecular-level insight into aggregation and exfoliation of graphene/graphene oxide (GO) is hindered by length and time scale limitations. In this work, we developed coarse-grained (CG) models of graphene/GO sheets, compatible with the...
