SIMULATION STUDIES ON THE DYNAMICS OF POLYMERS AT INTERFACES

Coarse-grained models of polymer chains interacting with hard walls ar e introduced and dynamics of the chains is studied in the framework of dynamic Monte Carlo simulations. Lattice models like the bond fluctua tion model and off-lattice beadspring model are discussed. The dynamic s of single chains at attractive walls in the vicinity of the adsorpti on transition is studied, with an emphasis on the question of whether the chain motion is described by the two-dimensional version of the Ro use model. For dense polymer systems confined between walls, the slowi ng down near the glass transition of the model is considered. Simulati ons are used to test various theoretical concepts and their applicatio n to experiment is discussed briefly.
