Generic morphologies of viscoelastic dewetting fronts
Stephan Herminghaus, Ralf Seemann, Karin Jacobs
Abstract
A simple model is put forward which accounts for the occurrence of certain generic dewetting morphologies in thin liquid coatings. It demonstrates that by taking into account the elastic properties of the coating, a morphological phase diagram may be derived which describes the observed structures of dewetting fronts. It is demonstrated that dewetting morphologies may also serve to determine nanoscale rheological properties of liquids.
