Title (EN) THREE-DIMENSIONAL GRAPHENE STRUCTURE, AND PREPARATION METHOD THEREOF
(FR) STRUCTURE TRIDIMENSIONNELLE DE GRAPHÈNE ET SON PROCÉDÉ DE PRÉPARATION
(KO) 3차원 구조의 그래핀 구조체 및 그 제조 방법
Abstract: front page image
(EN)The present invention relates to a preparation method of a three-dimensional graphene structure, and a graphene structure prepared by the method, the method comprising the steps of: preparing a dispersion in which graphite oxide is dispersed; and controlling the degree of reduction of the dispersion so as to prepare a gel. It is possible to provide a three-dimensional graphene structure having a specific surface area, pore size or volume per unit mass or the like suitable for the field to be applied thereto.
(FR)La présente invention concerne un procédé de préparation d'une structure tridimensionnelle de graphène et une structure de graphène préparée par le procédé. Selon l'invention, le procédé comprend les étapes : de préparation d'une dispersion dans laquelle de l'oxyde de graphite est dispersé ; et de commande du degré de réduction de la dispersion de façon à préparer un gel. Il est possible d'obtenir une structure tridimensionnelle de graphène ayant une aire, une taille de pores ou un volume spécifiques par unité de masse, ou analogue, appropriés au domaine auquel on l'applique.
(KO)본 발명은 그라파이트 산화물이 분산된 분산액을 제조하는 단계; 및 분산액의 환원도를 제어하여 겔을 제조하는 단계를 포함하는 3차원 구조의 그래핀 구조체 제조방법 및 상기 방법으로 제조된 그래핀 구조체에 관한 것으로, 적용하고자 하는 분야에 적합한 비표면적, 포어 사이즈 또는 단위 질량당 부피 등을 갖는 3차원 구조의 그래핀 구조체를 제공할 수 있다. [대표도] 도 1
