Nano-structured Polymer Surfaces — •P. Müller-Buschbaum1, M. Wolkenhauer2, M. Stamm3, and W. Petry11TU München Physik Department LS E13, James-Franck-Str.1, 85747 Garching — 2MPI für Polymerforschung, Ackermannweg 10, 55128 Mainz — 3IPF Dresden, Hohe Str. 6, 01069 Dresden

The interplay between phase separation, dewetting and micro-phase separation offers possible routes for the creation of nano-structured polymer surfaces. The regime of extremely thin films on the order of the radius of gyration is addressed [1, 2]. With advanced scattering techniques like grazing incidence small angle scattering and complementary real space techniques like SFM a determination of the morphology is achieved. Thus the topography as well as the chemical composition were determined as a function of key parameters like chemical potential or film thickness. A controlled design of tailor-made nanoscopic structures results.
