The article describes the multiscale experimental approach to the mechanical behavior of polymeric nanocomposites. It is based on a combination of structure sensitive methods with mechanical testing, which allows us to relate macroscopic mechanical behavior on one side, and molecular and supermolecular structure on the other. In addition to widely used X-ray scattering and microscope methods, solid-state NMR is applied in order to obtain information about structure and, primarily, about the dynamics of polymer segments. Particular attention is devoted to T1ρ(13C) relaxation experiments performed at variable 13C spin-locking fields.
