Monte Carlo simulations of the exchange kinetics of polymers adsorbed on a solid surface

摘要: The exchange kinetics of polymers adsorbing on a solid surface is extensively studied by dynamic Monte Carlo simulations. A model employed simulates semidilute polymer solution placed in contact with that attracts segments the adsorption interaction (X s ). process chains, between and adsorbed layer, examined under various conditions. shows two characteristic regimes increasing chain length. One diffusion-controlled regime found small X , other detachment-controlled large . These are well described kinetic theory. Various quantities show not due to sluggish dynamics near surface, but rather bulk diffusion chains. this study considered appear at high temperature limit.
