| Research Abstract |
The study on the structure and property of soft interfaces such as liquid/liquid interfaces is valuable, for example, in order to understand the correlation between the structure and function of more complicated molecular organized systems including emulsion, vesicle, and biological membranes. In this study, we aim at elucidating the stability of domain dispersion at soft interfaces from the viewpoint of domain line tension by interfacial tension and synchrotron X-ray reflectivity measurements. It was concluded that the the stability is governed by interplay among mainly four factors ; (1) domain line tension, (2) dipole interaction on the domain boundary, (3) interaction between domains, and (4) entropy of mixing of solute and solvent molecules around the domain. Furthermore, in case of spontaneous multilayer formation at soft interfaces, we claimed that the multilayer should be heterogeneous in thickness.
