Structure and Dynamics of Star Polymer Films from Coarse-Grained Molecular Simulations

We simulate the structure and dynamics of star polymer films of varying arm mass Ma and number of star arms f on a supporting solid substrate with an attractive interaction and compare to the corresponding properties of thin films of linear polymers. While the spatial variation of segmental density profile is only weakly dependent on star polymer topology, the polymer topology significantly affects both the average rate of relaxation and the...
