Abstract: front page image
(EN) 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.
(FR) La présente invention concerne un procédé de fabrication d'un nanodiamant de haute pureté (nD) présentant une dispersibilité améliorée, comprenant une étape de traitement thermique d'un nanodiamant, et selon la présente invention, le procédé de fabrication d'un nanodiamant de haute pureté présentant une dispersibilité améliorée est apte : à obtenir un nanodiamant hautement cristallin qui est complètement dispersé individuellement dans un liquide, par l'intermédiaire d'un processus de traitement thermique simple dans une plage de température spécifique dans l'atmosphère ; à permettre à des particules du nanodiamant hautement cristallin thermiquement raffiné d'être facilement dispersées dans le liquide sans coagulation, par l'intermédiaire d'un processus de dispersion ultrasonore ou électrostatique, même sans l'utilisation de dispersant séparé, de façon à être applicables en tant que composants matériels dans divers domaines tels que les machines, les automobiles, les trains, les navires et l'aviation spatiale, et de manière spécifique, d'être immédiatement modularisées à des douilles et analogues qui nécessitent une résistance et une résistance à l'usure ; étant censées être appliquées en tant que matériau de base pour divers matériaux d'affichage et ordinateurs quantiques étant donné qu'un effet de points quantiques peut être mis en œuvre ; et étant utiles en tant que matériaux de dissipation de chaleur pour des satellites artificiels et des dispositifs électroniques en raison des excellentes propriétés de dissipation de chaleur.
(KO) 본 발명은 나노다이아몬드(nanodiamond, nD)를 열처리하는 단계를 포함하는 향상된 분산성을 가지는 고순도 나노다이아몬드의 제조방법에 대한 것으로서, 본 발명에 따른 향상된 분산성을 가지는 고순도 나노다이아몬드의 제조방법에 의하면, 대기 분위기 하에서 특정 온도 범위로 열처리하는 간단한 공정을 통해, 액상 내에서 완벽하게 개별 분산되는(individually dispersed) 고결정성의 나노다이아몬드를 얻을 수 있으며, 또한, 상기 열정제된 고결정성의 나노다이아몬드 입자는 별도의 분산제를 사용하지 않고도 초음파 또는 정전기적 분산법을 통해 액상 내에 응집 없이 쉽게 분산되므로, 기계, 자동차, 열차, 선박, 우주항공 등의 다양한 분야에서 소재부품으로 적용이 가능하며, 특히, 강도와 내마모성이 요구되는 부싱류 등에 바로 부품화 할 수 있으며, 또한, 양자점 효과의 구현이 가능해 다양한 디스플레이 재료 및 양자 컴퓨터의 기본 소재로 적용이 기대되고, 우수한 방열성으로 인해 인공위성 및 전자기기의 방열재료로 유용하게 사용될 수 있다.
