Abstract

In this paper we describe in detail the phase diagram Cu(AOT)(2)-water-isooctane in the oil rich region. The phase diagram is very rich. All the phases described are thermodynamically stable. In this paper we concentrate in the isotropic region obtained at rather large water content (29 < w = [H2O]/[AOT] < 40). A transition from interconnected cylinder to reverse micelles is observed. At high surfactant concentration the system does not have enough oil to solvate the surfactant alkyl chains and large aggregates made of interdigitated reverse micelles are surrounded by isolated water in oil droplets.
