Mission statement

Our group utilizes block copolymers and block copolymer-based composites in form of bulk assemblies, nanostructured thin films, micellar structures, core-shell and yolk-shell particles as building blocks for the fabrication of various functional materials with potential application in catalysis, water purification, optical and magnetic components, etc.

What we do...

Block copolymers (BCP) are fascinating and, in some respects, unique materials that self-assemble into numerous ordered nanostructures. This research group focuses on design and fabrication of BCP-based nanostructured hybrid materials and nanocomposites with desired parameters, characteristic and properties. These hybrid materials have a wide range of potential applications, such as catalytic nanoreactors, water purification, nanosensors, optical waveguides, supercapacitors, and many others. We exploit so-called soft templating methods where BCP act as scaffolds for the incorporation of additives and/or as templates for directing of functionalization processes. Our objects of interest include BCP bulk structures, BCP thin films, and colloids. Synthetic methods for the preparation of such hybrids are quite diverse. For instance, the self-assembled block copolymers can be used as scaffolds for the controlled positioning of pre-synthesized nanofillers. Otherwise, the self-assembled BCP are used as structure-directing templates for the synthesis of inorganic counterparts (in-situ methods). Finally, different combinations of various synthetic methods are also possible and provide additional pathways towards multicomponent hybrids with multiple functionalities, and in variety of morphologies, like core-shell, yolk-shell, or hollow particles, nanofibers and nanotubes, etc. We exploit a variety of analytical methods and techniques to investigate and characterize our systems. We also focus on fundamental aspects of self-assembling phenomena in such complex multi-component systems in order to understand the processes, the structure-property relationship and to predict their behavior.
