| Research Abstract |
In a nonionic surfactant aqueous solution, we have investigated the morphology and the formation mechanism of the giant lamellar structures which are formed with crystallization of the hydrophobic group of a surfactant molecule inμm scale, by means of optical microscope, X-ray diffraction and light scattering. We have found that the structure of hydrophilic parts of a surfactant molecule contributes to the formation of the domain morphologies, and that a relatively stable disk-like domain in the case of large head area of the surfactant gradually becomes spherical vesicles because of the unstable structure of its edge part.
