Ternary systems NaAOT

Ternary reverse micelles composed of NaAOT, di(2-ethylhexyl) phosphoric acid (DEHPA) and di(2-ethylhexyl) phosphorothioic acid (DEPTA) in isooctane were studied by Rong et al. [129]. The results indicated that both water content and micellar size in this system were larger than in single surfactant systems with AOT and DEPTA. 

Before discussing the consequences of adding NaAOT into a mixture of water and IL, it is useful to review its behavior in water and in ternary (oil containing) systems. 

In Chapter 1, Murgia, Palazzo, and coworkers investigated the physicochemical behaviors of a binary IL bmimBF and water, and the ternary NaAOT, water and bmimBF mixtures essentially through the evaluation of the self-diffusion coefficients of the various chemical species in solution by PGSTE-NMR experiments. The diffusion of water molecules and bmimBF ions were found to be within different domains, which suggested that the systems were nanostructured with formation of micelles having positive curvature and a bicontinuous micellar solution for the former and the later systems, respectively. The remarkable differences between the two systems are attributed to the specific counterion effect between the aforementioned ILs and the anionic surfactant. In Chapter 2, Bermudez and coworkers focused on the characterization of small (conventional surfactants) and polymeric amphiphiles (block copolymers) in different types of ILs (imidazolium, ammonium.
