Research Focus of the Research Group Structural Polymers

Materials Testing

  • Thermal analysis to determine material-specific thermal transitions and behavior using DSC, TGA or DMA such as melting range, glass transition, crystallization behavior, degradation behavior
  • Mechanical analysis to determine mechanical parameters and the mechanical material behavior under different types of force and load. The test methods used include tensile tests, notched impact tests, hardness tests, bending tests, component tests, etc.
  • Rheological analysis to investigate the flow properties of the material in the melt. Conclusions about the structure of the polymer and its molar mass are possible. Investigation of non-linear behavior such as strain hardening.
  • Optical analysis and spectroscopy for the investigation of crystallization mechanisms, internal stresses, failure analyzes and plastic identification in the near-infrared range
  • Physical measurement methods such as density determination, scratch test and plastic identification

Evaluation of the recycling potential of various plastics

Our current research is currently very intensively concerned with the recycling possibility of polyolefins, as these play an important role in plastics production with a worldwide share of over 80%. Initial successes have already been achieved in the course of various projects. By characterizing and applying different material testing methods, the mechanical, rheological, thermal, optical and physical properties could be determined and show an improvement, which is why this represents a promising upcycling variant.
