In my talk I will present an overview of the structure and dynamics investigation of soft matter performed at the JCNS by neutron scattering and complementary methods. In particular, I will focus on polymer nanocomposites consisted of nanoparticles and grafted polymer chains (1-3) studied by SAS techniques and neutron spin-echo spectroscopy (NSE). As an example of applying the complementary methods I will present the pulsed field gradient (PFG) NMR study of blends of topologically different polymers (ring and linear) and passive macromolecular translocation mechanism through lipid membranes (4,5).
