Composite nanoparticles of detonation nanodiamond (DND) and polypyrrole (PPy) were produced in colloidal solution and on surfaces by wet chemical process. Changes of vibrational bands (in particular >C=O and C–H) in Fourier-transform infrared spectroscopy revealed the DND/PPy composite formation and tight interaction of PPy with hydrogenated DND (H-DND) and oxidized DND (O-DND). Atomic force microscopy showed uniform PPy coating but different PPy thickness on H-DND (7.0 nm) and O-DND (3.5 nm). These results suggest different bonding nature and arrangement of PPy on H-DND and O-DND surfaces.
