Title
(EN) PROCESS FOR PREPARING A CARBON NANOTUBE SHEET COMPRISING A UNIAXIALLY ALIGNED YARN AND CARBON NANOTUBE SHEET PREPARED THEREBY
(FR) PROCÉDÉ DE PRÉPARATION D'UNE FEUILLE DE NANOTUBES DE CARBONE COMPRENANT UN FIL ALIGNÉ UNIAXIALEMENT ET FEUILLE DE NANOTUBES DE CARBONE AINSI PRÉPARÉE
Abstract
(EN)
The present invention provides a process for preparing a carbon nanotube sheet, which comprises forming carbon nanotubes; aggregating the carbon nanotubes to form a yarn; treating the yarn with a solvent to enhance the aggregation force; winding the solvent-treated yarn to prepare a sheet preform having a structure in which one yarn is continuously wound; and cutting and/or pressing the sheet preform to prepare a carbon nanotube sheet that comprises an arrangement structure in which one or a plurality of yarns are uniaxially aligned, and a carbon nanotube sheet prepared thereby.
(FR)
La présente invention concerne un procédé de préparation d'une feuille de nanotubes de carbone, qui comprend la formation de nanotubes de carbone ; l'agrégation des nanotubes de carbone pour former un fil ; le traitement du fil avec un solvant pour améliorer la force d'agrégation ; l'enroulement du fil traité par solvant pour préparer une préforme de feuille ayant une structure dans laquelle un fil est enroulé en continu ; et la découpe et/ou le pressage de la préforme de feuille pour préparer une feuille de nanotubes de carbone qui comprend une structure d'agencement dans laquelle un ou une pluralité de fils sont alignés uniaxialement, et une feuille de nanotubes de carbone ainsi préparée.
