Influence of strain and slip on the dewetting of thin films — Andreas Reindl1,2 and •Markus Rauscher1,2 — 1Max-Planck-Institut für Intelligente Systeme, Stuttgart — 2Institut für Theoretische Physik IV, Universität Stuttgart
Thin polymer films produced by spin coating techniques often exhibit residual strain. We investigate the influence of this strain on the stability for the case of weak hydrodynamic slip at the substrate surface and for the case of strong slip (plug flow limit), i.e., we address the question whether a film dewets or not. The linear stability analysis of the corresponding thin film equations shows that for weak slip, residual strain does not destabilize the film. In the case of strong slip, however, sufficiently large residual strain can lead to dewetting of the film.
