Search for sustainable devices with improved efficiency and higher energy density. Use of the benefits of polymers: Light-weight and flexibility, tunability of the chemical design, and nanostructurig.

We are using a synergistic approach by combining expertise in the field of polymer synthesis, characterization and nanostructuring. We are searching for novel polymers and polymer/inorganic nanocomposites with tailored architectures and use block-copolymer templating and the tailoring of interfaces for the improvement of energy storage devices. By using nanoanalysis we are intending to understand structure-property-relations.
