Abstract
In this paper, we used low-field nuclear magnetic resonance (NMR) relaxometry and X-ray diffraction techniques to characterize polypropylene and to probe the polypropylene/clay interactions in non-exfoliated and exfoliated polypropylene–clay nanocomposites. Differences in T 1 H longitudinal relaxation time data and X-ray diffraction spectra were correlated with the presence of different domains in the samples studied. The results demonstrated the potential of H NMR relaxometry as a tool in the characterization of polymer–clay nanocomposites.
