Slippage and Nanorheology of Thin Liquid Polymer Films
Oliver Bäumchen, Renate Fetzer, Mischa Klos +4
Thin liquid films on surfaces are part of our everyday life, they serve e.g. as coatings or lubricants. The stability of a thin layer is governed by interfacial forces, described b…
Solid Surface Structure Affects Liquid Order at the Polystyrene/SAM Interface
Philipp Gutfreund, Oliver Bäumchen, Dorothee van der Grinten +5
We present a combined x-ray and neutron reflectivity study characterizing the interface between polystyrene (PS) and silanized surfaces. Motivated by the large difference in slip v…
Liquid Front Profiles Affected by Entanglement-induced Slippage
O. Baeumchen, R. Fetzer, K. Jacobs
Hydrodynamic slippage plays a crucial role in the flow dynamics of thin polymer films, as recently shown by the analysis of the profiles of liquid fronts. For long-chained polymer…
Comprehensive Analysis of Dewetting Profiles to Quantify Hydrodynamic Slip
Oliver Baeumchen, Renate Fetzer, Andreas Muench +2
Hydrodynamic slip of Newtonian liquids is a new phenomenon, the origin of which is not yet clarified. There are various direct and indirect techniques to measure slippage. Here we…
Thermal noise influences fluid flow in thin films during spinodal dewetting
R. Fetzer, M. Rauscher, R. Seemann +2
Experiments on dewetting thin polymer films confirm the theoretical prediction that thermal noise can strongly influence characteristic time-scales of fluid flow and cause coarseni…
Slip-controlled thin film dynamics
R. Fetzer, M. Rauscher, A. Münch +2
In this study, we present a novel method to assess the slip length and the viscosity of thin films of highly viscous Newtonian liquids. We quantitatively analyse dewetting fronts o…
