  • Member of the Czech Space Alliance (2013)
  • Nanotechnologies
    • Synthesis, surface modification and dispersion of nanostructures
  • Polymeric and nanocomposite systems
    • Synthesis, formulation, testing
    • Composites, adhesives, elastomers, coatings, foams, aerogels, sensors etc.


  • Pads and pastes with extremely high thermal conductivity (electrically conductive and non-conductive versions)
  • Nanohybrid transparent polyimide foils for thermo-optical applications (stability at 350 °C / 500 °C)
  • Multifunctional „black“ primer for thermo-optical applications
  • One component epoxy adhesive (storability ≥ 1 year, curing ≥ 120 °C)
  • Expandable adhesive curable at low temperature (≥ 70 °C)
  • Barrier coatings and composites with improved resistance against liquid gasses (LH2…)
  • Resins with extended pot life for out-of-autoclave manufacturing large and complex CFRP parts
  • “Green” conformal coatings and potting materials for electronics
  • Cryogenic insulation (foams, aerogels)
