Topological evolution in the ordered and isotropic phases of a lyotropic system
Résumé
In this review, after a brief overview of fundamental concepts involved in describing the geometrical properties of surfactant aggregates I summarize some results obtained recently by indirect studies on the topology changes in the well-known non-ionic lyotropic system C12EO6/H2O by measuring the diffusion constants of tracer molecules in the mesophases and by high-frequency rheology in the isotropic phase.
