Small angle neutron and xray scattering in external fields
A major challenge in today's research into an increased understanding in soft matter is the correlation between the macroscopic properties of polymers and its exact structure together with its dynamics. The small angle scattering technique, thereby changing the probe from xrays to neutrons, is a powerful tool to study bulk materials in different environments and external fields. Changing the contrast allows one to 'look' specifically at selected regions or length scales. The main research activities therefore focus on the structural response of polymers in elongated state in space and time in in-situ experiments or equilibrium conditions. These experiments are all coupled to rheology and mechanical analysis and based on model anionically made polymeric materials with H/D labeling and varying architecture.
