Surface modified nanodiamond, nanodiamond dispersion composition, and method for producing surface modified nanodiamond

摘要

PROBLEM TO BE SOLVED: To provide a polyoxyalkylene chain surface-modified nanodiamond which is excellent in safety during production and is excellent in productivity. The surface-modified nanodiamond of the present invention includes nanodiamond particles and a surface-modifying group having a polyoxyalkylene chain and a silicon atom, which surface-modifies the nanodiamond particles. The nanodiamond dispersion composition of the present invention includes a dispersion medium and the surface-modified nanodiamond dispersed in the dispersion medium. [Selection diagram] Figure 1
