Abstract

The adsorption phenomena of polyelectrolytes on oppositely charged surfaces are simulated by using an extended self-consistent field (SCF) theory to polyelectrolytes. Electrostatic potential is obtained by solving the Poisson equation coupled with the SCF equations. The behavior of the surface excess amount of the polymer, θ ex is compared between polyelectrolytes with uniform charge distribution along the chain and those with localized charge distributions. We observe that the latter case shows lower values of θ ex than the former case. However, in the case with higher surface charge density,polymers with two charges at one end of the chain show higher values of θ ex than those with single charge on each end orthan those with uniform charge distribution.
