METHOD FOR FUNCTIONALIZATION OF SURFACE OF DETONATION NANODIAMONDS Russian patent published in 2019 - IPC C01B32/15 B82B3/00 C01B32/28 B82Y40/00 

Abstract RU 2676975 C2

FIELD: materials science.

SUBSTANCE: invention relates to the field of materials science and can be used in the manufacture of nanomaterials. Homogeneous mixture of powders of nanodiamonds in the amount of 20–35 wt. % and polytetrafluoroethylene is subjected to thermochemical treatment in an inert atmosphere at a temperature of 420–500 °C to complete decomposition of polytetrafluoroethylene. Produce detonation nanodiamonds with fluorinated surface. Uniformity of concentration of fluorine-containing functional groups on the surface of nanodiamonds throughout the volume of the powder increases.

EFFECT: eliminating the need for radiation processing.
