Research topics

We aim at the deep understanding and controlling of macroscopic wetting and adhesion interfacial phenomena and their molecular origins. This knowledge might ultimately lead to the rational design of high performance multifunctional materials for various applications as adhesives, paints and protective coatings, functional composites, functional interfaces for solar cells and optoelectronics, as well as biomaterials. 

For this we develop new chemical approaches for the targeted interface design and modification using polymer grafting, polymer-brush-modification, coatings with core-shell hybrid colloids or plasma-modification. We address key questions concerning the molecular origins of wetting and adhesion as well as their correlation to chemical functionality, polymer architectures, surface charge, structural and topographical features and elasticity of materials. We use a unique combination of complementary physico-chemical, spectroscopic as well as direct force (AFM colloidal probe) measurements methods as a powerful tool for the thorough functional analysis and understanding of properties of interfaces.  

Our current research highlights are specifically focused on the bio inspired design of interfaces with tailored and controllable adhesion performance under wet, underwater, or extremely cold conditions/ icing environmental conditions.
