article i nfo Mixed polymer-surfactant systems have been intensively investigated in the last two decades, with the main focus on surfactant micelles as the surfactant aggregate in interaction. The…
Vesicle Formation and General Phase Behavior in the Catanionic Mixture SDS−DDAB−Water. The Anionic-Rich Side

The phase behavior in the cationic-rich side of the phase diagram of the mixed system sodium dodecyl sulfate (SDS)−didodecyldimethylammonium bromide (DDAB)−water at 25 °C is presented. DDAB is a…
Size and Stability of Catanionic Vesicles: Effects of Formation Path, Sonication, and Aging

The majority of vesicles prepared from dispersions of phospholipids in water are nonequilibrium structures. Thermodynamically stable vesicles must display distinctive physicochemical properties. To…
Self-assembly in mixtures of a cationic and an anionic surfactant: the sodium dodecyl sulfate-didodecyldimethylammonium bromide-water system
The phase equilibria of the sodium dodecyl sulfate (SDS)-didodecyldimethylammonium bromide (DDAB)-water system have been studied by water deuteron NMR and polarizing microscopy methods at 40 o C. 1 H…
Vesicle Formation and General Phase Behavior in the Catanionic Mixture SDS-DDAB-Water . The Anionic-Rich Side
The phase behavior of the mixture sodium dodecyl sulfate didodecyldimethylammonium bromide in water has been studied in detail, and two regions of isotropic vesicular phases (anionic-rich and cationic-rich) were identified.

The results suggest that the presence of micelles in the exfoliation process is not a key factor either for starting CNT dispersibility or attaining its saturation value, and the data indicate that the CNT-surfactant association follows patterns that are markedly different from other equilibrium processes governed by hydrophobicity.
