Molecular dynamics simulations of the graphene sheet aggregation in dodecane

Molecular dynamics simulations are used to investigate the aggregation and behavior of two parallel graphene sheets (22.0–64.0 A in length) in dodecane. The dodecane layer formed on the graphene surface leads to an energy barrier which slows the rate of the graphene aggregation process when the two sheets are totally separated by dodecane molecules. The graphene sheets aggregate in dodecane only when portions of one graphene sheet are in contact...
