Research Group Electron-Induced Material Modification

Research Fields

  • Electron induced reactive processing of polymer compounds (functionalization and crosslinking via e-beam)
  • Surface modification and nanostructuring of glass- or carbon fibers with carbon nanotubes (CNT), carbon black (CB) and graphene (GnP)
  • improving the durability of reinforcing fibers in composites by interphase modification
  • Investigation of the influence of filler combination with carbon nanotubes (CNT), carbon black (CB) or graphene (GnP) in melt mixing process on the resulting composite properties
  • Clarification of the filler dispersion mechanism (with and without processing additives)
  • Optimization of manufacturing processes, such as extrusion and injection molding in terms of morphological and electrical properties of the carbon filled composites
