Rod Formation of Ionic Surfactants: Electrostatic and Conformational Energies
We present a thermodynamic model that describes the formation of micelles from ionic surfactants in aqueous solution at varying counterion concentrations. The micellar aggregates may be spheres, dumbbells, and rods. A former theory [Heindl, A.; Kohler, H.-H. Langmuir 1996, 12, 2464] is refined by the introduction of detailed models for the conformational energy of the surfactant chains and the electrostatic interaction of the ionic headgroups. The standard Gibbs energy of a surfactant ion is...[Show more]
