Notizen:
The principles of NMR imaging applicable to materials are reviewed, and examples of current developments given. Among the different types of materials, polymers are particularly suitable for NMR imaging, because they are rich in protons, the most sensitive NMR nucleus. While the spatial resolution in solid materials is restricted to dimensions larger than 50 μm, the interest in NMR as an imaging technique derives from the abundance of parameters, which can be converted to image contrast for localization and identification of material morphology, chemistry and physics. Particular progress has been achieved in imaging of polymer melts and liquids, where diffusion and non-Newtonian flow are investigated as well as of elastomers, where composition, deterioration by thermal and mechanical aging, and stress distribution can be characterized.
