Dynamic nuclear polarisation NMR of nanosized zirconium phosphate polymer fillers

Abstract

Surface functionalisation with organic modifiers of multi-layered zirconium phosphate (ZrP) nanoparticles used as polymer fillers can be directly probed by dynamic nuclear polarisation NMR, which provides unambiguous evidence of the presence of P–O–C chemical bonds at the surface of the ZrP layers, thereby confirming successful functionalisation.
