The values of δL index show that the simulated ensemble is in a stable, twodimensional liquid state on graphene; no phase transition appears for the studied
temperatures 280 K < T < 330 K. The major contribution to δL comes from the
motion of βCD molecules in the ultra-thin molecular layer naturally formed on the
surface of graphene.
In conclusion, the molecular dynamic (MD) computer simulations of βcyclodextrins—graphene systems show that βCD molecules spread all over the
