How molecular dynamics is coupled to nanostructuration in ultra flexible microemulsions ?
UltraFlexible MicroEmulsions are typically ternary mixtures of common solvents forming "surfactant-free microemulsion". From a structural point of view, such mixtures present nanostructuration that varies between the regions of the phase diagram, forming bicontinuous, water continuous or nanodroplets. This ability for mesostructuration may take its origin in the structure of alcohols, but the influence of molecular diffusivities in the formation and life time of the (dynamical) aggregates, yet, has not been clarified. This is the aim of our current project. Initiated on water/ethanol/octanol solutions, we need to complete our picture with the characterization of two other systems: water/ethanol/ethyl-hexanol to probe the effect of molecular branching and water/sodium salicylate/ethyl acetate where pre-nucleation is observed. We will be able to compare the dynamics in three different situation of aggregates formation: pre-Ouzo region, vicinity of the critical point and pre-nucleation. NMR measurements on a much larger lengthscale will then complement the molecular dynamics probed by NSE, known to be surprisingly different. We request here 5 days on WASP and 4 days on IN15.
