systems. We explore the effect of graphene on the mobility of polymers, by studying three
well known and widely used polymers, polyethylene (PE), polystyrene (PS) and poly (methyl-
methacrylate)(PMMA). Qualitative and quantitative differences in the dynamical properties of
the polymer chains in particular at the polymer–graphene interface are detected. Results
concerning both the segmental and the terminal dynamics render PE much faster than the …
