Thermodynamic properties of ring polyelectrolytes in thebinding mean spherical approximation.
Résumé
A simple model for charged ring polyelectrolyte is proposed, to describe their thermodynamic properties. Starting from an analytical expressions previously obtained for charged chains within the binding mean spherical approximation, we present a method to determine suitable modifications in order to describe charged rings. It is shown that the electrostatic excess thermodynamic properties can still be computed from relatively simple formulas which involve a screening parameter Γ B .
