Complex polymer systems

theory and simulation

Research activity of the group focuses on the conformational behavior and self-assembly of polymers, copolymers and particularly polyelectrolytes in bulk solutions and in confining media. Computer modeling of the behavior of systems important for chromatography, biomedical and environmental applications and for various nanotechnologies represent major part of the research. Nevertheless, experimental studies (mostly by scattering and spectroscopic methods) are also carried out in cooperation with colleagues from the Soft matter group and with collaborators from the Academy of Sciences of the Czech Republic and from abroad.

Research topics

Complex polyelectrolyte solutions (mesoscopic simulations)

Polyelectrolytes and especially polyelectrolyte amphiphilic copolymers are stimuli multi-responsive and usually water-soluble. So, they meet today requirements for cheap, environmentally friend, and non-toxic materials for smart applications in medicine, technological ...

Electrostatic co-assembly

In polyelectrolyte systems, the long-range Coulomb interactions dominate the behavior at large scales. Their competition with the short-range interactions between hydrophobic chain units and water molecules results in unique properties ...

Amphiphilic copolymers under geometrical confinement

The confinement effects complicate significantly the polymer behavior, however they simultaneously provide opportunities to generate novel nanostructures useful for advanced applications such as nanocontainers or molecular templates. Detailed knowledge of ...
