Simulation Study of Polymer Crystallization in Confined Geometries — •Hendrik Meyer — Laboratoire Européen Associé – Institut Charles Sadron; 6, rue Boussingault; 67083 Strasbourg (France)

A recently introduced coarse-grained model suitable for studying polymer crystallization from the melt [1] is applied in molecular dynamics simulations in confined geometries. In contrast to the melt, crystallization starts at much higher temperatures because the walls serve as nucleation centers. This simulates thus heterogeneous nucleation which will be compared to the results of homogeneous nucleation from the supercooled melt [1]. The simulation gives insight into single chain trajectories and the growth process.
