Behavior of polyelectrolyte solutions in a wide range of solvent dielectric constant
Original language description
We exploit the strong temperature dependence of dielectric constant of N-methylformamide to control the strength of electrostatic interactions in polyelectrolyte solutions of sodium polystyrene sulfonate, and investigate the dynamic properties of salt-free solutions over a broad temperature range, from 54 to 58 °C. The traditional fast and slow diffusion processes are observed. The ratio of diffusion coefficients, Ds/Df, increases and the ratio of their amplitudes, As/Af, decreases, both by a factor ofabout two in this temperature range confirming the expected temperature variation with the Bjerrum length.
