Association behaviour of glucitol amine gemini surfactants - Self-consistent-field theory and molecular-dynamics simulations
(2002) In European Physical Journal E. Soft Matter 7(4). p.317-324- Abstract
- The association behaviour of a number of glucitol amine gemini surfactants has been investigated by means of molecular dynamics and self-consistent-field calculations. We have shown that the titratable head group of the surfactant is responsible for a micelle-to-membrane transition when changing the pH. Furthermore, the association structure of this group of surfactants is shown to be very sensitive to ionic strength. The combination of a charged head group, a spacer, and the hydrophilic glucitol side chains is responsible for the possible structural transitions in the associates as a function of ionic strength and pH.
