X-ray Lab

We offer X-ray scattering methods for structure determination on different lengths scales in bulk, fibers, thin films and layers.

Additionally, the application of synchrotron radiation experiments (e.g., Photon Science at DESY Hamburg) via diverse proposals (manly for GISAXS) we provide.

Fields of work

  • solid state structure of polymers, copolymers, blends, composites, nanoparticles (clay, LDH, CNT, …), measured as bulk, powder, fibers, stretched specimens, …
  • order parameters (crystallinity, qualitative + semi-quantitative phase analysis, selective orientation and texture parameters, crystallite size, …)
  • phase separation on nano- and micrometer scale (dmax ~130 nm)
  • temperature-dependent structure changes (-100 °C … 350 °C)
  • thin film and surface characterization
