Simulation studies on the dynamics of polymers at interfaces

Coarse-grained models of polymer chains interacting with hard walls are introduced and dynamics of the chains is studied in the framework of dynamic Monte Carlo simulations. Lattice models like the bond fluctuation model and off-lattice beadspring model are discussed. The dynamics of single chains at attractive walls in the vicinity of the adsorption transition is studied, with an emphasis on the question of whether the chain motion is described by the two-dimensional version of the Rouse model. For dense polymer systems confined between walls, the slowing down near the glass transition of the model is considered. Simulations are used to test various theoretical concepts and their application to experiment is discussed briefly.
