Abstract: Thermodynamic stability of graphene against stacking in the gas phase and in different solvents (N-methyl-2-pyrrolidone), dimethyl sulfoxide, and water) has been investigated using the semi-empirical PM6 method combined with supermolecular approach, and with Periodic Boundary Conditions using Density Functional Theory in conjunction with the Perdew-Burke-Erzernhof functional. In the case of a supermolecular approach, the effect of the ratio of the edge and the center part on the solvation enthalpy has also been investigated.
