Prof. Christine Papadakis

Forschungsgebiet

Das Fachgebiet Physik weicher Materie befasst sich mit den Struktur, Dynamik und Kinetik von nanostrukturierten Polymersystemen, u.a. amphiphilen und schaltbare Blockcopolymeren, dünnen Polymerfilmen, sowie Polymeren für medizinische Anwendungen. Es werden hauptsächlich Streumethoden eingesetzt, sowohl an Großforschungsanlagen als auch im Labor.

Neuartige schaltbare zwitterionische Polymere

Switchable polymers in solution change their behavior strongly upon a stimulus, such as a small change of temperature, pH or ionic strength. The so-called zwitterionic polymers show such behavior: They carry both positive and negative charges, and their behavior seems to differ strongly from common switchable polymers. Moreover, slight changes of the chemical structure lead to strong and counterintuitive changes of the behavior.

In the thesis, the solubility behavior of zwitterionic polymers in aqueous salt solution 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.

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.

Quellverhalten multiresponsiver Polymerfilme

Multiresponsive polymers strongly change their properties upon variation of temperature, pH, ionic strength, for instance. In thin film geometry, they may serve as smart, nanostructured coatings. In the present thesis, thin films from such block polymers shall be prepared, and their swelling behavior shall be investigated in dependence on prepararation conditions, solvent used for swelling, and temperature. Time-resolved grazing-incidence small-angle X-ray scattering at the synchrotron may give insight into the structural changes.

In the thesis, the swelling behavior of switchable polymers under various conditions shall be studied using white-light interferometry, X-ray reflectometry and grazing-incidence 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.
