Description:

Researchers are interested in studying and controling the ordering of soft materials, especially (but not only) at surfaces. In thin films of block copolymers control of the organization at the supramolecular level can lead to the formation of nanostructures on a macroscopic scale. To influence the pattern formation a second ordering principle can be introduced as a control parameter ('tandem' interactions), for example liquid-crystal (LC) ordering.  Understanding the interplay between disordered and ordered assembly on the nanoscale is very important to enable use of chemical reactions to control growth of nanostructures.
