Screened hydrodynamic interactions in ternary polymer solutions
Résumé
This paper discusses the effects of screened hydrodynamic interactions in ternary polymer solutions. The inclusion of a screening length ξH in the Oseen tensor allows a good description of the wavevector dependence of the relaxation frequencies characterizing the mixture. In the limit of infinite screening length ξH ↦∞, the full hydrodynamic interaction is recovered whereas for infinitely short length ξH ↦0, the Rouse behavior is obtained. The method can be applied to arbitrary mixtures but for simplicity it is presented here in the symmetrical case.
