In this project, we want to study the structure of interfaces and the wetting behavior of amphiphilic systems. In particular, we want to investigate the interfaces between ordered mesophases, which are characterized by long-range translational order. These phases can be described very well by Ginburg-Landau-type models, which contain a term which favors the formation of internal interfaces.In more detail, we want to investigate the following problems:1. The structure of interfaces between ordered mesophases - like the lamellar and the hexagonal phase - and a structured surface.2. The structure of interfaces between different ordered mesophases, and between different domains of the same mesophase.3. The wetting behavior on structured and unstructured surfaces at coexistence of different mesophases, or at coexistence of an ordered mesophase with the isotropic phase.4. The dynamical behavior of a wetting film of a bicontinuous microemulsion at coexistence with oil and water.

在本计画中，我们将研究两亲性体系的界面结构与润湿行为。特别是，我们要调查有序的中间相，其特征在于长程平移顺序之间的接口。这些相可以用Ginburg-Landau型模型很好地描述，该模型包含一个有利于内部界面形成的项。有序中间相（如层状相和六方相）与结构化表面之间的界面结构。2.不同有序中间相之间的界面结构，以及同一中间相不同畴之间的界面结构.不同中间相共存或有序中间相与各向同性相共存时结构化和非结构化表面的润湿行为。4.油水共存时双连续微乳液润湿膜的动力学行为。
