COMPETENCES INTERFACIAL ENGINEERING AND MATERIALS SCIENCE Material surface requirements are often very different from the properties intrinsic to the bulk of the material concerned. Actually, for many applications the material surface is of crucial importance, for example in medical engineering or ad- sorber materials. The department offers a variety of processes for ilm deposition from either the gas or liquid phase. We also develop polymeric and inorganic material systems with Research focus Protective layers, permeation barriers, release coatings Coatings with minimized interfacial energy for improved emptying behavior or reduced ice adhesion Biofunctional coatings Formulation of bio-inks for bioprinting Water puriication with membranes, adsorbers and water large surface areas such as particles, porous membranes, non- contact plasmas woven materials and foams as well as biomaterials, especially hydrogels. A multitude of analytical tools are available for the monitoring of processes (process diagnostics) and the charac- terization of the generated material surfaces. Apart from the quality of the products, the material and energy eficiency of processes is of foremost concern. Plasma cleaning and sterilization processes Nano- and micro-structured materials Core-shell particles for separation and formulation of substances Membranes for gas separation, pressure-retarded osmosis (PRO), PEM fuel cells and membrane reactors Technology and expertise Deposition of thin monolayers or multiple ilms from the gas phase (e.g. plasma) Chemical modiication of surfaces (dip coating, doctor- blading, printing etc.) Generation and loading of functional nanoparticles using polymerization methods or spray drying Production of polymeric and ceramic separation membranes by phase inversion processes Synthesis of biocompatible polymers, chemical modiication of biomolecules, development of biomaterials Contact Determination of interfacial energy, topography, adsorption, and chemical composition of surfaces Plasma process diagnostics: probe measurements, optical and mass spectrometric methods 3 4 Hon.-Prof. Dr. Christian Oehr Head of Department, Director (acting) Phone +49 711 970-4137 christian.oehr@igb.fraunhofer.de
