Chain conformation of poly(butylene oxide) silica nanocomposites — •Adrian Hamm, Wim Pyckhout-Hintzen, Andreas Wischnewski, Jürgen Allgaier, and Dieter Richter — Jülich Centre for Neutron Science JCNS and Institute for Complex Systems ICS, Jülich, Deutschland

Poly(butylene oxide) silica mixtures have proven to be a nanocomposite model system with many desirable features. As poly(butylene oxide) does not crystallize this opens up the possibility to investigate its behaviour with many different methods over a very broad temperature range. After preliminary small angle x-ray scattering experiments to prove good particle dispersion we used rheology and boradband dielectric spectroscopy experiments to gather information about the changes in sample behaviour that can be introduced by adding silica nanoparticles. As a next step we wanted to gain more microscopic insight and performed small angle neutron scattering experiments on our samples. We now want to present first results of these recent experiments on poly(butylene oxide) silica nanocomposites and show what we leared about the change in chain conformation introduced by the nanoparticles.
