Interfacial Engineering and Materials Science
Interfaces of materials are the surfaces where the materials more or less interact with their environment. Interfaces play a supporting part in the development of materials and components in the automotive sector, of technical textiles or in medical technology. For many materials the surface properties required are often quite different from those which are intrinsic for the bulk material. To modify their properties, the interfaces are first characterized in detail, and then are functionally modified using plasma technology or supramolecular chemistry.
Plasma processing is nowadays one of the most important tools in thin film and surface treatment technologies, and thus plays a key role in manufacturing of many innovative products. For this reason, applications of plasma in surface technology belong to main research interests of the Fraunhofer IGB. The used plasmas are low temperature, low-to-medium pressure ones, enabling a gentle and controlled surface processing. This way we are able to etch surfaces, e.g. to clean them, or to graft new chemical functionalities onto the surface. It is also possible to polymerize a thin film onto the surface, providing such functions as as scratch-resistance, dirt-repellency, or corrosion protection. By controlling the gas composition, power and other process parameters, a broad spectrum of chemical, physical and biological surface modifications is attainable.
