Polymere in tief eutektischen Lösungsmitteln

Deep eutectic solvents (DES) are a new class of designer solvents composed of hydrogen bond donor and hydrogen bond acceptor molecules. The mixture has a substantially lower melting point than the pure substances and remains liquid at room temperature. They may be called "green solvents". In the master thesis proposed, thermoresponsive polymers shall be studied in these solvents. In water, these are soluble up to a certain temperature, above which, they become water-insoluble. Since this behavior is strongly related to hydrogen bonds, new insight can be gained by using hydrogen bonding solvent.

In the thesis, the solubility behavior of switchable polymers in DES shall be studied using turbidimetry, dynamic light scattering and small-angle X-ray scattering. After a literature research, the sample preparation, measurement and data analyis shall be carried out. For more information, please contact Prof. Christine Papadakis, papadakis@tum.de.

Selbsassemblierung polymerer Flaschenbürsten in wässriger Lösung

“Polymeric bottle brushes” consist of a long polymeric backbone with a large number of densely grafted side chains. They resemble a bottle brush with a stiff backbone and the side chains sticking out. They form compact nanoscopic objects with many possibilities for end group functionalization. We have investigated a special type, namely bottle brushes where each side chain features a water-soluble and a water-insoluble block.

In the project proposed, the self-assembly behavior of these complex polymers in aqueous solutions shall be studied in dependence on molecular architecture and composition as well as on polymer concentration. Moreover, as a simple reference system, di- or triblock copolymers from the same components will be investigated.

At this, dynamic light scattering and small-angle X-ray scattering shall be used in our laboratories as well as small-angle neutron scattering at a research reactor. The data will be analyzed by model fitting. This way, detailed knowledge about the role of the molecular architecture on the self-assembly behavior will be gained.

Kondensierte Materie

Wenn Atome sich zusammen tun, wird es interessant: Grundlagenforschung an Festkörperelementen, Nanostrukturen und neuen Materialien mit überraschenden Eigenschaften treffen auf innovative Anwendungen.

Kern-, Teilchen-, Astrophysik

Ziel der Forschung ist das Verständnis unserer Welt auf subatomarem Niveau, von den Atomkernen im Zentrum der Atome bis hin zu den elementarsten Bausteinen unserer Welt.

Biophysik

Biologische Systeme, vom Protein bis hin zu lebenden Zellen und deren Verbänden, gehorchen physikalischen Prinzipien. Unser Forschungsbereich Biophysik ist deutschlandweit einer der größten Zusammenschlüsse in diesem Bereich.
