Oil-swollen lamellar phases

A special case is that of rigid interfaces with a spontaneous curvature close to zero, such as the case of oil-swollen lamellar phases, when long-chain doubletailed surfactants form oil-swollen layers separated by water layers. These phases present strong geometrical constraints and the thickness of layers are easily measurable with precision by means of scattering experiments. The variation of composition associated with the addition of a solute can be detected by visual inspection between crossed polarizers and by chemical analysis. However, to our knowledge, no experimental results on curvature variation, area per molecule variation and maximum admissible concentration of a solute in these systems is yet available.
