Title: METHOD FOR MANUFACTURING THERMALLY REFINED HIGH-PURITY NANODIAMOND HAVING IMPROVED DISPERSIBILITY
Abstract:
The present invention relates to a method for manufacturing a high-purity nanodiamond (nD) having improved dispersibility, comprising a step of thermally treating a nanodiamond, and according to the present invention, the method for manufacturing a high-purity nanodiamond having improved dispersibility is capable of: obtaining a high-crystalline nanodiamond which is completely individually dispersed within a liquid, through a simple heat treatment process in a specific temperature range under the atmosphere; allowing particles of the thermally refined high-crystalline nanodiamond to be easily dispersed in the liquid without coagulation, through an ultrasonic or electrostatic dispersion method even without using a separate dispersant, so as to be applicable as material components in various fields such as machinery, automobiles, trains, vessels, and space aviation, and specifically, to be immediately modularized to bushings and the like which require strength and wear resistance; being expected to be applied as a basic material for various display materials and quantum computers since a quantum dot effect can be implemented; and being useful as heat dissipating materials for artificial satellites and electronic devices due to excellent heat dissipating properties.
