Adhesion mediated by polymers, multivalent adhesion

Adhesion in polymeric systems occurs on various levels: Our research concentrates primarily on adhesion processes on the level of single polymer chains. We utilize single molecule force spectroscopy that allows determining the interaction of single... details...

Electrets

The incorporation of permanent charges in polymer films (e.g. by corona charging), is a long-known effect that has many applications, such as in the electret microphone. Despite the widespread use of these materials there remain many open questions... details...

Thin polymer films and polymer adsorption

Polymer adsorption and film formation are important processes at solid interfaces, which have many practical applications. In our research we study polymer adsorption primarily by means of well-defined model systems. One current research field is t... details...
