Molecular interactions revealed by structure and dynamics in ternary mixtures forming surfactant-less microemulsions
The mixture of two completely miscible molecular liquids and a third one (water) that is only poorly miscible with one of these two other liquids may lead to a nano-sructuration forming surfactant-less microemulsion. These solutions are excellent solubilizers and candidates in terms of formulation for green chemistry, but very little is know on the microscopic mechanisms driving the structuration of the liquid according to its composition, from a homogeneous phase to a complete separation. Following preliminary studies, we propose here to get a characterization of the structure and dynamics over the full Q range of interest, i.e. from the molecular scale to Ouzo-droplet regime. We will investigate in a first time the model system octanol/ethanol/water, and investigate the role of interactions with different molecular substitutions of the oil by varying its structure and the hydrogen bond network. We request for this extended study 5 days on IN15, 5 days on WASP and 2 days on D33.
