摘要
Highly charged semiflexible polyelectrolyte chitosan was characterized in dilute and semidilute aqueous solutions in the presence of excess of salt by viscosity and static and dynamic light scattering. In the present paper, we report on the variation of the structural and dynamical parameters as a function of the ionic strength. Size of the polyions, virial coefficients and overlap concentration are parameters that are strongly influenced by excess salt concentration.
