Title:
METHOD FOR PRODUCING NANODIAMOND DISPERSION COMPOSITION, AND NANODIAMOND DISPERSION COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2020/195328
Kind Code:
A1
Abstract:
Provided are: a method for producing a nanodiamond dispersion composition which has excellent dispersibility of nanodiamond particles in a dispersion medium while preventing the inflow of zirconia beads; and a nanodiamond dispersion composition obtained by said method. A method for producing a nanodiamond dispersion composition according to the present invention comprises: a preparation step in which a crude nanodiamond product is obtained by the detonation process; an oxidation treatment step in which an oxidizing agent is used to remove graphite from the crude nanodiamond product obtained in the preparation step; and an in-liquid plasma treatment step in which nanodiamond, which has been subjected to the oxygen treatment step, is subjected to plasma treatment in a liquid, and dispersed.
