C-13 CP/MAS NMR Study of Cross-linked Poly(vinylpyrrolidone) on Surface of Cerium Oxide Nanoparticles
The highly dispersed property of poly(vinylpyrrolidone) (PVP)-coated cerium oxide nanoparticles can be retained for a long time in polar solvents. In this C-13 CP/MAS NMR study, it is revealed that the surface PVP forms cross-linked structures during the synthesis of the nanoparticles.
