| Research Abstract |
Although it has been known that the shear flow induces structural transition in the lyotropic phase (self-assemblies with a long-range order) composed of amphiphiles, the transition mechanism remains still unclear. In this study, we have focused on the transformation of the surfactant lamellar phase into the onion phase where the multilamellar vesicles are close-packed. We have found for the first time the lamellar→onion and lamellar→onion→lamellar transition with increasing temperature under shear flow.
