경직된 고분자의 분배거동 = Partitioning of a Stiff Polyelectrolyte

다국어 초록 (Multilingual Abstract)

We investigate theoretically the partitioning behavior of a uniformly-charged polyelectrolyte confined in a circular cylindrical pore with constant electric potential on its surface. On the basis of the first order perturbation theory, predictions on the partition coefficient are made in a variety of situations. The intramolecular interactions between pairs of monomers are found to be as much important as the direct polymer-pore interaction in determining the partition coefficient. Depending upon the ionic strength of the embedding electrolyte solution, the polyelectrolyte conformation gets stretched or follows self-avoiding walk, yielding a significant reduction in the partition coefficient compared to the ideal chain result.
