Single polyelectrolyte macromolecule in the salt solution: Effect of escaped counter ions

摘要: We developed simplest theory of swelling polyelectrolyte macromolecules in the solution low-molecular salts. The novel feature taken into account electrostatic interaction between macro-ion and counter ions which escaped from interior macromolecular coil distributed whole volume solution. phase diagram variables solvent quality vs. salt concentrationis derived. One unexpected findings is that total charge within sphere surrounding changes a non-monotonical manner with increase concentration. In particular, our calculations predict electrophoretic mobility macromolecule can demonstrate non-monotonic behavior an results are compared those obtained under assumption electroneutrality when all kept effective macromolecule.
