Local segmental dynamics in one component polymer nanocomposites
Local hydrogen dynamics of one component nanocomposites (OCNC) composed of core-shell nanoparticles (NP) grafted with polymer will be studied. NP core consists of cross-linked deuterated polybutadiene, the NP shell is represented by deuterated and hydrogenated poly(ethylene oxide) (PEO) chains. Specifically, incoherent dynamics of the hydrogenated PEO chains in the shell and dynamics of cross-linker molecules in the NP core will be investigated in the Q-range from 0.4 to 1.8 1/AA and on the time scale from 0.1 to 100 ps. As a reference the hydrogenated PEO chains in the bulk will be measured. The results obtained at IN5 are crucial to separate properly the coherent and incoherent contributions to the dynamic cross section in our recent experimental data obtained by NSE (WASP@ILL). Taking into account measurements at a few temperatures, resolution and background measurements we ask for 4 days of beamtime at the IN5 instrument.
