Abstract: front page image
(EN)A method for printing a CNT three-dimensional structure is disclosed. The present invention provides a method for preparing a CNT composite structure, comprising the steps of: providing, to a nozzle, an ink in which a CNT composite comprising CNTs and a flow control agent; positioning the nozzle at a predetermined point on a substrate; and printing a CNT composite pattern corresponding to the movement path of the nozzle by moving the nozzle along a predetermined path on the substrate while discharging the ink from the nozzle, wherein in the step of printing a CNT composite pattern, the pattern is stacked as the CNT composite by the evaporation of a solvent within the meniscus formed by the ink to be discharged from the nozzle between the nozzle and the substrate. According to the present invention, a CNT structure comprising CNTs as a main component can be prepared, a pattern can be continuously formed by a pressureless method without the clogging of a nozzle or the cutting off of ink, and the prepared CNT structure can firmly maintain the injected shape.
(FR)La présente invention concerne un procédé d'impression d'une structure tridimensionnelle de nanotubes de carbone (NTC). La présente invention porte sur un procédé de préparation d'une structure composite de NTC, comprenant les étapes consistant à : fournir, à une buse, une encre dans laquelle un composite de NTC comprenant des NTC et un agent de régulation de l'écoulement; positionner la buse en un point prédéterminé sur un substrat; et imprimer un motif en composite de NTC correspondant au trajet de déplacement de la buse par déplacement de la buse le long d'un trajet prédéterminé sur le substrat tout en éjectant l'encre depuis la buse, où, dans l'étape d'impression d'un motif en composite de NTC, le motif est empilé en tant que composite de NTC par l'évaporation d'un solvant à l'intérieur du ménisque formé par l'encre devant être éjectée de la buse entre la buse et le substrat. Selon la présente invention, une structure de NTC comprenant des NTC en tant que constituant principal peut être préparée, un motif peut être formé en continu par un procédé sans pression sans le colmatage d'une buse ou la découpe de l'encre et la structure de NTC préparée peut conserver fermement la forme injectée.
(KO)CNT 3차원 구조체의 인쇄 방법이 개시된다. 본 발명은 CNT 및 유동 조절제를 포함하는 CNT 복합재가 분산된 잉크를 노즐에 제공하는 단계; 상기 노즐을 기판 상의 소정 지점에 위치시키는 단계; 및 상기 노즐로부터 상기 잉크를 토출하면서 상기 기판 상의 소정 경로를 따라 상기 노즐을 이동시켜 상기 노즐의 이동 경로에 대응하는 CNT 복합재 패턴을 인쇄하는 단계를 포함하고, 상기 CNT 복합재 패턴 인쇄 단계에서, 상기 패턴은 상기 노즐과 상기 기판 사이에서 상기 노즐로부터 토출되는 상기 잉크에 의해 형성된 메니스커스 내의 용매의 증발에 의해 CNT 복합재로 적층되는 것을 특징으로 하는 CNT 복합재 구조체의 제조 방법을 제공한다. 본 발명에 따르면, CNT를 주성분으로 하는 CNT 구조체의 제조가 가능하게 되며, 무가압 방식으로 노즐의 폐색이나 잉크의 끊김 없이 연속적인 패턴 성형이 가능하고, 제조된 CNT 구조체는 사출된 형상을 견고히 유지할 수 있다.
