(a) The amount of adsorbed proteins during the process of protein desorption, (b) potentials of mean-force in the initial state before surface adsorption, the inset is the local enlarged profile at the adjacent area (the grey box) of the surface, (c) volume fractions of grafted polymers, the inset is the dissociating fraction of the polymer, and (d) dimensionless electrostatic potentials within the layer for four different pH cases.
