Abstract.
Molecular-dynamics simulations of thin polymer films are performed with a recently introduced coarse-grained model. This model reproduces many features of polymer crystallization from the melt. In this work, we show how confining walls influence the structure formation depending on the degree of supercooling. Already in the melt at high temperature a preorder is induced near the walls. On lowering the temperature, crystalline order nucleates at the walls, from which it propagates into the film. We show how this growth can be influenced by prestructuring the wall.
