The integration timestep was 0.001 τ , and T was controlled by a Langevin thermostat with friction coefficient 0.1 m/τ applied to each particle. Linker-patch bonding energy was increased to βε = 10 over 10 4 τ , followed by a 10 4 τ equilibration period. Linker-patch energy was then further ramped by k B T over a 0.5 × 10 4 τ period, followed by reequilibration for 1.5 × 10 4 τ . This process was repeated nine times to reach ε = 20. Final configurations saved from this annealing protocol were thermalized for 2 × 10 3 τ at βε = 100 and subsequently used as the initial states for the uniaxial elongation simulations described below.
