Abstract
(EN)
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.

L'invention concerne : un procédé de production d'une composition de dispersion de nanodiamant qui présente une excellente dispersibilité de particules de nanodiamant dans un milieu de dispersion tout en empêchant l'entrée de billes de zircone ; et une composition de dispersion de nanodiamant obtenue par ledit procédé. Un procédé de production d'une composition de dispersion de nanodiamant selon la présente invention comprend : une étape de préparation dans laquelle un produit de nanodiamant brut est obtenu par le processus de détonation ; une étape de traitement d'oxydation dans laquelle un agent oxydant est utilisé pour éliminer le graphite du produit de nanodiamant brut obtenu dans l'étape de préparation ; et une étape de traitement au plasma dans un liquide dans laquelle le nanodiamant, qui a été soumis à l'étape de traitement à l'oxygène, est soumis à un traitement au plasma dans un liquide, et dispersé.
