Research topics

Both chemical and physical properties of interfaces as well as their spatial arrangement, dynamics and adaptivity are important for proper materials performances. To this line our group has strong expertise and competences in polymer science, physical chemistry of colloids and interfaces, soft materials, which includes controlled synthesis and modification of interfaces, physical-chemical evaluation of their properties and fundamental understanding of correlations between macroscopic interfacial phenomena and their molecular origins, as well as development of strategies for rational design of soft and hybrid materials with controlled wetting and adhesion properties.

For this, our group is developing synthetic routes for the controlled large-scale design of libraries of soft and hybrid organic-inorganic colloids consisting of inorganic core (SiO2, TiO2, BaTiO3) and polymer shells possessing controlled chemical functionalities, symmetric and  Janus architectures, various shapes (spheres, platelets, rods, cubes), sizes, mechanical properties and responsive properties.

Our group is fundamentally interested in investigating the self-assembly of isotropic and anisotropic colloids, which are able to form structures and clusters of different shapes (raspberry-like, dumbbells, chains) rapidly, reversibly and controllably. We are addressing the kinetics of self-assembly showing that kinetically favored isomers join to form highly ordered but dynamic non-equilibrium large scale structures.  

Finally, our group transposes the obtained fundamental knowledge to the rational design of materials for interfacial catalysis, wet and dry adhesives, functional coatings with controlled icing and (bio-)fouling properties as well as ferroelectric composites.
