Study of polymers by scattering methods (synchrotron radiation, X-ray scattering).
Development of evaluation methods and algorithms. dynamical-mechanical
analysis (DMA), differential scanning calorimetry (DSC), ellipsometry.
The two-phase nanostructure of many plastics materials is causing their
peculiar physical properties. In semicrystalline polymers size and distribution
of crystalline domains determines the hardness of the material. In thermoplastic
elastomers the elastic properties are a function of the purity of the solidified
glassy phase (hard domains) (phase separation). Typical dimensions of the
studied domains are ranging from 3 nm to 300 nm.
Utilizing brilliant synchrotron radiation, we study changes of the morphology
of the nanocomposite material during melting and recrystallization as well
as during straining and fibre spinning. We register morphological changes
caused by solid or liquid extenders and are intensely involved in the task
to gain a clear understanding of processes and structures related to materials
properties by developing methods for the quantitive, multi-dimensional
analysis of nanostructure data from X-ray methods.
