Abstract

The polymer brush bilayer under non-equilibrium shear inversion is studied by means of MD simulations. The temporal evolution of the shear stress reveals that there is no overshoot during shear inversion. Moreover, the shear extension of chains undergo two minimums in the first and third quarter of the shear inversion and one maximum in the middle of the shear inversion. Therefore, the works already published about finding a way to suppress the shear stress overshoot and maintain mechanical stability are wrong.
