  • Research focus

    • Molecularly programmable block copolysaccharides
      The aim is to prepare block copolysaccharides through the orthogonal coupling of oligosaccharide blocks and to establish design principles for block architectures enabling an entirely new class of materials with molecularly programmable properties.
    • Structurally programmable mechanical metamaterials
      We investigate the use of machine learning to identify relationships between structural variables and the properties of mechanically robust metamaterials with programmable acoustic damping.
    • Reactive modification of polymers and fillers
      We explore the relationships between reaction parameters, structure, and properties of reactively modified polymers.
    • Functional nanocomposites and their 3D printing
      We use machine learning to design nanocomposite formulations, including the control of direct multimaterial 3D printing of mechanically robust phononic polycrystals with programmed acoustic damping.
    • Electrically conductive polymer materials
      We focus on the use of unique forms of carbon-based fillers in thermoplastic matrices to enhance electrical conductivity and reduce the percolation threshold of the filler.
    • Polymer materials for shielding electromagnetic and ionizing radiation
      We develop polymer composites with controlled morphology forming an electrically conductive “network” for electromagnetic shielding of cables. The development of these materials is primarily motivated by requirements for low weight, stability, corrosion resistance, and easy processability.
    • Hybrid WPC composites from recycled polyolefins
      We develop a new generation of circular materials based on recycled ICP-PP with a programmed spatial arrangement of hybrid fillers across three dimensional scales, forming a hierarchical stress-transfer structure required for load-bearing and structural applications. The goal is to create a new design framework for structural materials with a high recycled content.
