Nanodiamond dispersion composition

Abstract

Provided is a nanodiamond dispersion composition having excellent dispersibility of nanodiamond particles in an organic dispersion medium. A nanodiamond dispersion composition including an organic dispersion medium, nanodiamond particles dispersed in the organic dispersion medium, and a fatty acid ester dispersing agent, the nanodiamond particles being surface-modified by a surface-modifying group or compound containing an organic group. The fatty acid ester dispersing agent preferably has a mass loss rate of 30% or less when held in an air atmosphere at a temperature of 200° C. for 180 minutes.
