▎ 摘  要

The exemplary properties of graphene and the potential inclusion of nanoparticles have suggested applications in energy storage, catalysts and sensing. A critical feature of the performance of these nanocomposites is the distribution of nanoparticles and the exposed area of the graphene. Here we report a computational analysis exploring the effect of the dispersion of nanoparticles between layers of graphene, characterizing both solvent accessible surface area (SASA) and inter-graphene adhesion energy (Delta E-g). We find a maximum number of nanoparticles before the accessible graphene surface area decreases, and a limit where the system separates as the graphene layers no longer 'stick'.
