In addition to the studies of fundamental problems in polymer physics, the scientific activities
of the Polymer Research Group are directed to questions of materials science and focus on the comprehensive characterization of macromolecular systems having potential applications as polymeric sensors, polymer emissive displays and in the field of colloids. One of the main research topics is the investigation of struc- ture formation of functional polymers under the influence of external mechanic, magnetic and electric fields; special interest is devoted to the kinetics of reorienta- tional processes and ferroelectric switching in liquid crystalline polymers and to thermally stimulated currents in conjugated polymeric systems. The orientational parameters are investigated as well as the local polarization and space charge distri- bution which are of importance in the application of thin-layer dielectric systems.
Main methods of investigation in this field are the Nuclear Magnetic Resonance
(NMR), the Laser Intensity Modulation Method (LIMM) and
Thermally Stimula- ted Depolarization Current (TSDC). A second
main research interest is the investi- gation of dynamics and molecular interactions at interfaces with at least one fluid component. This research area is especially relevant to transport processes (diffusion and self-diffusion as well) which are studied using
Static (SLS) and Dynamic Light Scattering (DLS) and Pulsed Field Gradient NMR (PFG-NMR).
Scientific collaboration exists with the Institute
of Polymer Research Dresden e.V., the Institute of Macromolecular Chemistry of the Academy of Sciences of the Czech Republic (Prague),
the Institute of Physical Chemistry of the Russian Academy of Sciences (Moscow) and with the Universities of Darmstadt, Durham, Freiburg and Lausanne.
