Název v původním jazyce

Surface chemistry of water dispersed detonation nanodiamonds modified by atmospheric DC plasma afterglow

Popis výsledku v původním jazyce

In this contribution we report on a low-cost method for modifying DNDs dispersed in water by atmospheric DC plasma afterglow. DNDs were used either in as-received form (labeled as H-DND) or after air-annealing at 450 °C for 30 minutes (labeled as O-DND). The influence of applied voltage and thus the type of discharge (corona discharge at 10 or transient spark discharge at 15 kV) and treatment duration (1, 5 and 10 minutes) on the surface chemistry of DNDs was evaluated by Infrared spectroscopy (IR). We observe interesting changes on both oxygen- and hydrogen- containing surface functional groups on colloidal H-DNDs by the atmospheric DC plasma afterglow. Origins and implications of these changes will be discussed.n
