Exploring the effect of tube dilation in bidisperse blends of long and shortPEO chains using ring polymers as probes
Objective of this proposal: This proposal aims at the investigation of the unrelaxed diluted tube diameter of entangled chains (dPEO, 200.000 g/mol) in dependence of its dilution with short chains (dPEO, 1.000 g/mol) from the dynamic structure factor via neutron spin echo spectroscopy using ring polymers (hPEO, cyclic, 20.000 g/mol) as probes (see scientific background). The underlying static structure factors of the sample and the reference systems will be investigated by small angle neutron scattering (scheduled at KWS-2, MLZ, Garching, Germany, in May 2016).
