Tag hinzufügen | Zusammenfassung: | Göttingen, Univ., Diss., 2012 The properties of polymer films and droplets at substrates of different topography are studied employing particle-based simulation techniques (Molecular Dynamics). The liquid is modeled by short coarse-grained polymer chains of 10 monomers, while the temperature of the system is controlled by the Dissipative Particle Dynamics (DPD) thermostat that conserves momentum locally and provides correct hydrodynamics. Throughout this dissertation we show that macroscopic concepts cannot be straightforwardly extrapolated down to microscopic systems. At first the flat topography of the substrate is st... |
