Role of the functional group position in producing viscoelasticity in micellar solutions: A ¹H NMR study

This is the authors' abstract. We don't add key points for this paper.

Abstract 1 H NMR spectra of cetyltrimethylammonium bromide (CTAB) micellar solutions in the absence and presence of sodium anthranilate (NaAn) have been recorded. Studies were performed at a fixed CTAB concentration in the presence of different NaAn concentrations. The specificity of the functional group attached to the salt in producing changes (i.e., viscoelasticity) in CTAB micellar solutions was explored. It was concluded that the nature of the salt counterion together with its intercalation/adsorption in the head group region is the principal cause of viscoelasticity.
