Structure formation at interfaces: breath figures and beyond — •Masoud Amirkhani — Institut für Experimentelle Physik Universität Ulm Albert-Einstein-Allee 11 89081 Ulm, Germany

The interaction of two (or more) different materials in contact is crucial for basic science as well as for practical purposes. At the micro and nano regime, the number of molecules at the interface is comparable to that of bulk molecules so the interaction at the interface governs the overall structure and functionality of the system. The interface interaction is particularly crucial for the formation of emulsions, microemulsions and surface micelles. Additionally, the existence of a large interface does directly affect the adsorption of polymer on the surface and the performance of many systems such as ionic polymer metal composites (IPMC). One should note that the interface interaction can be altered using various physical and chemical stimuli. For example amphiphilic and amphiphilic-like molecules are able to modify surfaces and interface properties and also form self-assembled structures. In this talk, we present the investigation of the size and structure of surface emulsion and microemulsions under the influence of different additives. Additionally, the conformation and configuration of diblock copolymer on the substrate under the influence of solvent vapor annealing and electric field will be discussed.
