The dissertation “Dewetting and Structure Formation at Polymer-Polymer Interfaces” by Odo Wunnicke investigates the stability and structural evolution of thin polymer films at interfaces between different polymers. The research focuses on dewetting mechanisms and the formation of self-organized surface structures. Using polymer bilayer systems, the study examines how thermal annealing, solvent vapor treatment, and interfacial energies influence wetting behavior. Experimental methods include atomic force microscopy, X-ray scattering, and neutron scattering techniques. Particular attention is given to spinodal and binodal dewetting processes and the development of characteristic surface patterns. The research also demonstrates how the addition of suitable copolymers can delay dewetting and improve the stability of polymer films. The findings contribute to understanding interfacial phenomena and developing strategies for producing stable thin polymer coatings.
