Advanced Nanomanufacturing

In the polymer nanotechnology group we develop enabling techniques for the patterning of functional surfaces, and use these processes in different research and application fields. Because most of the processes are centered around the nanostructuring of polymers, these activities are strongly linked to the “Institut für Nanotechnische Kunststoff-Anwendungen (INKA)” at the University of Applied Sciences Nordwestschweiz FHNW (founded in 2004). This is particularly important for techniques with the potential for industrial production, such as nanolithography, nanoreplication, and surface functionalization.
