Adsorption and Depletion of Polyelectrolytes from Charged Surfaces
, 2003 Mean-field theory and scaling arguments are presented to model polyelectrolyte adsorption from semi-dilute solutions onto charged surfaces. Using numerical solutions of the mean-field equations, we show that adsorption exists only for highly charged ...
