Average bond forces along the z direction for ring polymers with chain length N = 122 for various topological constraint value rn as a function of the distance from the surface. (a) Linear polymer brushes, (b) ring polymer brushes with topological constraint value rn = 1, (c) ring polymer brushes with topological constraint value rn = 5, (d) ring polymer brushes with topological constraint value rn = 10.
