摘要：

An extended phase diagram for an ionic microemulsion system made of water, n-decane, and the ionic surfactant sodium-di-2 ethyl-hexyl sulfosuccinate is deduced from a very extensive set of electrical-conductivity and neutron-scattering measurements. This diagram shows high-temperature phase transitions that explain some original features previously not reported. Furthermore we propose a phenomenological model based on the solution of a Poisson-Boltzmann equation which accounts well for electrical conductivity data we obtain in the lamellar phase.
