      abstract     = {Combining the functionality of nanoparticles and polymers
                      leads to a novel class of materials: nanocomposites.
                      Nanoparticles like magnetic nanoparticles or quantum dots
                      (QDs) can be used to introduce new properties into polymeric
                      matrices. This could be the response to a magnetic field or
                      photoluminescence. Polymers can provide stability, add
                      elasticity or animproved processability, they can be
                      functionalised by supramolecular groups to allow
                      nonpermanent bonds between the polymer chains. The
                      combination of those properties makes nanocomposites deeply
                      interesting for a range of applications like coatings,
                      membranes, organic solar cells or biomedicine. The
                      additional structuring of nanoparticles within the polymer
                      matrix allows for an even wider range of tuneable
                      properties. Obtaining stable nanocomposites in external
                      fields is highly desirable but challenging due to the
                      usually encountered aggregation of nanoparticles in polymer
                      matrices. Therefore, compatibilization of the two components
                      is essential to study their controlled spatial organisation.
                      The aim of this work is the development of a route towards
                      magneto-elastomeric nanocomposites with supramolecular
                      activity. For this, functional nanocomposites are
                      synthesised, and their structure characterised by
                      small-angle scattering methods. First, the behaviour of
                      superparamagnetic, oleic acid stabilised iron oxide
                      nanoparticles, in a magnetic field is investigated by
                      small-angle neutron scattering (SANS). It is found that
                      already at low magnetic fields, the nanoparticles form
                      chains, which are aligned parallel to the magnetic field
                      while crystalline phases dominate the measured structures at
                      higher field strengths. To be able to make use of this
                      behaviour in a nanocomposite, a compatibilization of the
                      nanoparticles and the polymer matrix is necessary. The
                      solution developed here, relies on the coating of the
                      nanoparticles with a polymer shell. [...]},
