Structure and Dynamics of Macromolecules

The fast developments in the synthetic chemistry during the last decades enabled the preparation of a large variety of macromolecules with controlled topology and functionality. We focus on understanding the relation between molecular architecture, composition and processing on one hand and the morphology and physical properties of the macromolecular materials on the other. Such understanding is not only of fundamental interest but will also help to design new materials for various applications. Specific research topics include:

  • Mobility in polymer networks -> Kaloian Koynov, Hans-Jürgen Butt
  • Polymer crystallization in confinement -> George Floudas
  • Macromolecular complexes in solution -> Kaloian Koynov, Hans-Jürgen Butt
  • Photo-responsive polymer materials -> Si Wu
  • Structure and dynamics in ultrathin polymer film Kaloian Koynov, Markus Mezger, Werner Steffen, George Floudas
  • Macromolecules with complex architecture -> Markus Mezger, Kaloian Koynov, George Floudas
  • Functional nano-structured materials -> Werner Steffen, Rüdiger Berger, Markus Mezger
We investigate forces associated with sliding drops and apply advanced scanning force microscopy methods. more
We are interested in the interplay of structure and dynamics in soft condensed matter. We apply scattering techniques and dielectric spectroscopy, respectively. Systems of interest include nanostructured polymers, biopolymers, liquid crystals and ionic systems in the bulk and under confinement. more
We develop fluorescence correlation spectroscopy and related methods to address research questions in the field of polymer, colloid and interface science. more
Based on photoswitchable azobenzene or Ru complexes we construct photoresponsive polymers and supramolecules. We control glass transition temperatures, adhesion, phase transitions, colors, morphologies, etc. with light. Upconverting nanoparticles allow us to construct near-infrared (NIR) light-responsive materials that are useful for deep-tissue biomedical applications. more
