NANO-DIAMOND DISPERSION LIQUID AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A nano-diamond dispersing solution and a method for manufacturing the same are provided to increase the dispersibility of a solution by increasing the electrical repulsive force between nano-diamond particles using a metal hydroxide. CONSTITUTION: A nano-diamond dispersing solution is obtained by dispersing a nano-diamond, in which a particle diameter thereof is between 1 and 100nm, in a dispersing solvent. A method for manufacturing the nano-diamond dispersing solution includes the following: Nano-diamond aggregate is prepared(S10). The nano-diamond aggregate is mixed with a metal hydroxide aqueous solution to form a mixed solution(S20). The mixed solution is stabilized to be separated into supernatant and precipitate(S30). The supernatant and the precipitate are respectively extracted(S40). The supernatant is dried(S50). The supernatant is mixed with the dispersing solvent(S60).
