  "abstract": "Using molecular dynamics (MD) simulations with a Langevin thermostat, I study polymer brush bilayers immersed in an implicit solvent under steady-state shear. I use high-precision MD simulations, with 5×104 sampling steps, to measure the stress tensor, viscosity, kinetic friction coefficient, and chain extension as functions of the shear rate. The results show that the shear stress scales linearly with the Weissenberg number, Wi, over the entire range studied. The normal stress decreases without following a universal power law. The lateral chain extension decreases up to a critical value of Wi and then increases. The normal chain extension scales as Wi−0.3. The viscosity remains constant, whereas the kinetic friction coefficient increases without following a universal power law.",
