Title:
METHOD AND DEVICE FOR MANUFACTURING NANODIAMONDS
Document Type and Number:
WIPO Patent Application WO/2016/052807
Kind Code:
A1
Abstract:
The present invention relates to a method and device for manufacturing nanodiamonds, the method comprising the steps of: providing a first member, which is made of a carbon material, electrically connected between electrodes within a chamber having a liquid contained therein, and a second member, which is made of a carbon material or a conductive material, spaced apart from the first member and electrically connected between the electrodes; and applying electrical energy to the electrodes so as to produce nanodiamonds through a collision between the first and second members, which is caused by a shock wave due to electrical explosion in the liquid and attraction due to electromagnetic force. Therefore, the present invention can produce nanodiamonds by causing a plurality of carbon materials or a carbon material and a conductive material to collide with each other by an accelerated collision due to electromagnetic force therebetween and by a shock wave due to electrical explosion, and the so-produced nanodiamonds can be easily purified and dispersed. Further, the present invention can easily separate pure nanodiamonds from carbon residues and obtain nanodiamonds which are dispersed without agglomeration.
