Abstract

Different techniques are used to characterize the structure of the sponge (L3) phase in the bulk of the partial isothermal surface of the phase diagram of the sodium dodecyl sulfate/ 1-pentanol/ cyclohexane (C6)/ and water mixture. A water layer of thickness delta separates two nonconnected regions in C6.

Abstract

The wetting of a substrate by a lyotropic sponge phase is studied by using grazing X-ray scattering and optical microscopy. The wetting promotes the formation of an anisotropic layer with tetragonal symmetry on a length scale of ~10 nm on the substrate. It is also identifies the surface field with one due to the selective ionic adsorption as the candidate responsible for the observed change of structure from melted cubic to tetragonal.

Abstract

Examines the use of flow-induced optical birefringence to characterize the phase diagram of the ternary lyotropic mixture of sodium bis sulfosuccinate, dodecanol and water. Existence of a bicontinuous structure; Manifestation of inverted sponge phase in micellar isotropic inverted phase; Observation of lamellar and cylindrical phase diagram.
