Abstract

The electrical conductivity of a three-component ionic microemulsion has been measured in the phase diagram region where the lamellar phase, made up of repeated layers of water, surfactant and oil, exists. The data have been analyzed on the basis of an effective medium theory expression, taking into account the ion distribution within the water layer according to the Poisson-Boltzmann equation. — PACS numbers: 64.60.
