Materials Design of
Advanced Multifunctional Nanostructured Materials and the
Analysis of their Physical Properties
Considerable R&D efforts are necessary for an integrated processing of nanostructured and composite functional materials. In recent years, special field- and pressure-assisted synthesis and processing technologies with extreme pressure and temperature conditions were developed allowing the access to a wide range of new compounds, metastable phases and bulk materials with ultrafine microstructures due to the ultrafast energy transfer to the precursor materials during their non-equilibrium processing. A special feature of these new technologies is the ability to consolidate dissimilar materials (metallic particles, polymers, ceramics) into complex nanostructured systems.
Our research group uses hybrid technologies that integrate soft-chemical synthesis (colloidal chemistry, sol-gel) with mechanical activation, pulsed current or microwave radiation processing and magnetron sputtering. The versatility and innovative character of these new hybrid technologies result from the unique design of the processing sequence that alternates physical and chemical synthesis steps, accessing a variety of ways to influence the end-product material properties.
Advanced Multifunctional Nanostructured Materials
The development of advanced materials and their engineering on nanoscopic length scales matured to an important key technology in recent years. The creation of atomic and molecular nanometer sized units – a million times smaller than a pin head - and their combination lead to new materials with tailored functionalities. The size reduction and the internal interfaces have important influences and the combination of metals, ceramics or polymers lead to additional possibilities.
