| Outline of Final Research Achievements |
Although the transition from the surfactant lamellar phase into the “onion phase” where all the space is filled by multilamellar vesicles has been reported for many systems, conditions of onion formation and the transition mechanism are still unclear. We have performed the following studies by using simultaneous measurements of rheology/small-angle X-ray scattering（rheo-SAXS）and simultaneous measurements of rheology/small-angle light scattering（rheo-SALS) for a nonionic surfactant (C14E5)/water system.
(1) Development of a double cylinder cell which can be used both for SAXS and SALS. (2) Determination of a temperature-shear rate diagram and elucidation of three-dimensional structures of the onion phase with a long-range orientational order. (3) Determination of the intermediate structure between lamellar and onion phases formed in the low-shear rate region.
