DNDs were used in as-received form (labeled as H-DND) or after air-annealing (labeled as O-DND). The influence of applied voltage (10 and 15 kV) and treatment duration (1, 5 and 10 minutes) on the surface chemistry of DNDs was evaluated by FTIR spectroscopy. Plasma treated H-DND particles reveal i) decreasing ratio of CH3 to CH2 surface groups; ii) disappearance of double bonds present in the graphitic shell of the particles and iii) re-arrangement of residual oxygen-containing moieties on the particle surface. In contrast to H-DNDs, the chemical state of O-DND surface was not affected by plasma treatment. In this case, newly formed doublet at 1580 and 1604 cm-1 was detected whose origin is not clear yet. Complementary XPS and Raman measurements did not reflect any changes of DNDs after the plasma treatment.
