Here, the spring constant is k s = 30ε/σ 2 and the maximum spring extension is r max = 1.5σ, where r ij is the distance between two connecting beads and σ and ε are the length and energy parameters, respectively. Excluded volume interaction among the beads was represented using the Weeks-Chandler-Anderson 96 potential for simulations in a very good (athermal) solvent. The Lennard-Jones potential truncated at 2.5σ was used for simulations under non-athermal conditions. A bending potential of the standard cosine form was applied only to the backbone beads, with a bending constant k b = 0.5k B T , where k B is the Boltzmann constant and T is the absolute temperature. Although a bending potential for the backbone beads is not necessary for a generic bottlebrush model, we included it to account for the specific polymer chemistries considered in the experimental system.
