Abstract
The present invention relates to a nano-diamond dispersion solution and a method of preparing the same. The method of preparing a nano-diamond dispersion solution comprises the following steps: providing a nano-diamond aggregation; mixing the nano-diamond aggregation with a metal hydroxide solution and stirring the mixture such that the nano-diamond aggregation is separated, to obtain a mixture solution; stabilizing the mixture solution such that the mixture solution is separated into a supernatant and precipitates; and extracting the supernatant and precipitates.

A nano-diamond dispersion prepared using the method comprising:
- providing a nano-diamond aggregation;
- mixing the nano-diamond aggregation and an aqueous metal hydroxide solution while agitating to prepare a mixture solution in order to disintegrate the nano-diamond aggregation;
- stabilizing the mixture solution to be separated into a supernatant and a precipitate;
- and
- extracting the supernatant and the precipitate respectively from the mixture solution;
- wherein the nano-diamond dispersion includes nano-diamond particles having a particle size of from about 1 nm to about 100 nm dispersed in a dispersion solvent.
