Soft Matter Physics

Prof. Christine Papadakis

Research Field

The Soft Matter Physics Group investigates the structure, dynamics and kinetics of nanostructured polymer systems, e.g. amphiphilic and switchable block copolymers, thin polymer films, as well as polymers for medical applications. We mainly use scattering methods both at large facilities and in the lab.

Responsive, self-assembled nanoparticles

Amphiphilic block copolymers having a permanently hydrophobic block and a thermo-responsive block form nanoparticles, or rather core-shell micelles, in aqueous solution. The structure of these micelles is controllable by changing the temperature or the ratio between the hydrophobic and the hydrophilic block. These properties enable amphiphilic block copolymers as candidates for a wide variety of applications, such as drug delivery. The main goal of this thesis is to investigate above which polymer concentration micelles form and to characterize the size of the micelles by fluorescence correlation spectroscopy.  For more information, please contact Prof. Christine Papadakis, papadakis@tum.de.

Switchable polymeric brushes

Poly(2-ethyl-2-oxazoline) (PEtOx) in aqueous solution is a responsive polymer which suddenly dehydrates, becomes water-insoluble and collapses, when the sample is heated through the lower critical solution temperature (LCST). We investigate molecular brushes, in which PEtOx chains are densely-grafted on a polymer backbone. The compact architecture has an influence on the dehydration and collapse behavior, and the entire brush changes structure when the side chains collapse.

In the suggested bachelor project, the influence of the architecture on the collapse behavior shall be investigated using Fourier-transform infrared spectroscopy (FTIR) and dynamic light scattering (DLS). After a literature research, samples will be prepared and measured, and data analysis will be carried out. For more information, please contact Prof. Christine Papadakis, papadakis@tum.de.

Doubly-responsive polymer nanoparticles

Amphiphilic block copolymers having a permanently hydrophobic block and a responsive block form core-shell micelles in aqueous solution. The structure of these micelles is controllable by changing the temperature or pH value. These properties enable amphiphilic block copolymers as candidates for a wide variety of applications, such as drug delivery. The main goal of this thesis is to investigate the effect of the pH value on the transition temperature and the micellar size. At this, differential scanning calorimetry (DSC) and dynamic light scattering will be used. For more information, please contact Prof. Christine Papadakis, papadakis@tum.de.
