Physics of Soft Matter Interfaces

We study the structure and dynamics of interfaces. Our aim is to better understand the relationship between structural changes, dynamics, and the driving forces. Complex processes shall be explained in terms of the fundamental physical laws and molecular configurations. Major topics are interfacial forces and the dynamics at solid-liquid interfaces, including wetting, evaporation, condensation, and the hydrodynamic boundary condition. We investigate liquids that are internally structured at different length scales, such as polymer melts, solutions, dispersions, or emulsions. The methods we use include scanning probe techniques, confocal microscopy, focused ion beam, microrheology, light and X-ray scattering. To expand the range of length and time scales accessible, new methods are continuously developed. Our goal is to solve fundamental questions, with the perspective of future applications.
