Dynamics of Diblock Copolymers in patterned thin films — •Marianne Heckmann1, Marcus Müller2, and Barbara Drossel1 — 1Institut für Festkörperphysik, TU Darmstadt — 2Institut für Theoretische Physik, Georg-August-Universität Göttingen
We investigate the ordering process of symmetric diblock copolymers which are confined between two hard walls. One of the walls has a stripe pattern with stripes that attract the A-component of the copolymer while the opposite wall is neutral. We use dynamic self-consistent field theory in order to describe the ordering of the melt. We are interested in the time until the system is perfectly ordered into perpendicular oriented lamellae and the structures which occur during the ordering process. We present results for different distances between the stripes at the walls in a two-dimensional system for systems with two or three stripes.
