S.A.N.S. Spectra and Elastic Plateau Modulus in a Charged Wormlike Micelles Solution: Effect of Salt

Abstract

We present S-A-N-Sand elastic plateau modulus data obtained from semi-dilute wormlike micellar solutions, with small amounts of salt added. The spectra of these solutions are reminiscent of polyelectrolyte send-dilute solutions. The plateau modulus, which is related to the correlation length of the fluctuations in strain, is increased by the addition ofsalt. The primary result is that the electrostatic interactions induce short-range correlations in the structure of the semiflexible rod network, and tlds leads to a long-range correlation in the strain fluctuations. It has long been known that wormlike micelles can be formed in various surfactant solu-
