The center-of-mass height H_cm for polymer brushes with different topological constraints versus chain length N at grafting density ρ = 0.1d⁻² and chain length N = 62. The inset shows the scaling exponent ν as a function of topological constrain value, indicating a less sensitive dependence of structure height on chain length.
