Multiscale approach to mechanical behavior of polymeric nanocomposites:

an application of T1r(13C) relaxation experiments at variable spin-locking fields (in English)

Polimery 2014, No 9, 662


DOI: dx.doi.org/10.14314/polimery.2014.662

Summary

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 T1r(13C) relaxation experiments performed at variable 13C spin-locking fields.


Key words: polyamide 6, nanocomposite, T1r(13C) relaxation, molecular dynamics, fracture toughness
