Nowadays adaptive synthetic polymer materials which are able to change their properties on demand play important role in nanotechnology. In contrary to conventional polymer nanocomposites, the nanoparticles functionalized with a polymeric shell, which takes the role of a matrix, allow to control the distance between the nanoparticles and homogeneously dispersed per definition. Determining factors are size of the core, grafting density, length of the grafting chain and temperature. Supramolecular functionalization (H-bonds) of the grafting chains leads to additional steps in adaptiveness. Moreover, using magnetic nanoparticle as a core extends the application area to e.g. magnetorheological nanocomposites. In this talk I will focus (1) on the structure of magneto-elastomeric nanocomposites with supramolecular activity and (2) polymer chain dynamics in one component nanocomposites (OCNC) studied by neutron scattering.
