Molecular Systems and Materials Chemistry (MSMC) 67 and, in particular, the relationship between chemical structure and end-use properties. It includes the elucidation of structure-property relationships by means of different (chemical, structural, rheological, mechanical and thermal) characterization techniques. In cooperation with industry (e.g., BASF), various industrially relevant applications of the new materials will be evaluated. 2. Novel high-performance aerogels Aerogels are low-density solids with high open porosity and surface area, exceptionally low thermal conductivities and high acoustic attenuation. They are typically prepared from suitable wet gels by turning the pore-filling solvent into a supercritical fluid which is vented off. In this project, we aim to create the next generation of organic aerogels with outstanding mechanical, chemical and thermal stability and flame retardancy by developing novel aerogels based on high-performance structural motifs. They can be envisioned as lightweight super-insulating materials for aerospace applications, as well as for more down- to-earth uses in construction and transportation. Additionally, they will be used for energy storage and membranes and in catalytic applications. 3. Dynamic and self-healing polymers The development of new concepts for autonomous self-healing is initiated on the basis of e.g., block copolymers or supramolecular polymers consisting of high T g domains which provide good mechanical properties and low T g domains featuring supramolecular hydrogen bonding interactions that are responsible for the healing behavior. Research in this area is focused on an understanding of the scratch healing mechanism (relevant for real applications) and on functionality obtained through the sophisticated use of specific supramolecular interactions, particularly multiple hydrogen bonding. The performance of the materials is evaluated in various industrially relevant applications, such as protective films, coatings and adhesives (technical and film-to-film lamination). A similar approach can be used for the development of systems (e.g., elastomers, sealants, coatings and adhesives) with bonding/debonding on demand. 4. Circular polymer materials Polymers are central materials for our present and future society and have enabled us to improve the quality of all aspects of our daily life. However, our lifestyle also generates serious problems due to the ways in which we use polymers. Most polymers are discarded after use, rarely recycled and end up in landfills, rivers and oceans. This fate is a typical example of the current linear and fossil-based produce-use-discard value chain that causes
