Abstract
The kinetics of wormlike micelles formed in aqueous solutions of binary mixtures made of cetylpyridinium chloride and sodium salicylate in the presence of 0.5 M NaCl has been investigated by means of T-jump and rheology experiments. The micellar lifetime was found to follow power laws of the concentration with exponents in agreement with the theoretical models. The scission energy of the micelles was determined by combining T-jump and linear viscoelasticity measurements as a function of temperature. This paper also reviews previously reported rheological studies and presents a general discussion on the correlation between different dynamical mechanisms and counterion binding.
