The first part of this work concerned the study of the pretransitional effects that appear upon heating in the ordered phases of the binary lyotropic mixture C12EO6/H2O on approaching the transition towards the isotropic phase. Using a photobleaching technique, we measured the diffusion constants of fluorescent dyes as a function of temperature. We showed that structural defects connecting the surfactant structure appear in the lamellar and hexagonal phases and determined their structure and density. We inferred that the isotropic phase itself is highly connected close to the mesophases. This conclusion is supported by the fact that the diffusion constant does not vary at the transition between the isotropic and cubic bicontinuous phases.We...
