Title
(EN) NANOSHEET AND METHOD FOR THE MANUFACTURE THEREOF
(FR) NANOFEUILLE ET SA MÉTHODE DE FABRICATION
Abstract
(EN)
In an embodiment, a method for preparing a nanosheet comprises mixing a raw material having a hexagonal crystal structure, an acid, and a salt to form the nanosheet having a hexagonal crystal structure; wherein the raw material comprises at least one of a hexagonal boron nitride, a hexagonal molybdenum disulphide, a hexagonal graphite, or a hexagonal tungsten disulphide; and isolating the nanosheet.
(FR)
Dans un mode de réalisation, une méthode de préparation d'une nanofeuille comprend le mélange d'une matière première ayant une structure cristalline hexagonale, d'un acide et d'un sel pour former la nanofeuille ayant une structure cristalline hexagonale ; la matière première comprenant au moins un nitrure de bore hexagonal, un disulfure de molybdène hexagonal, un graphite hexagonal, ou un disulfure de tungstène hexagonal ; et l'isolement de la nanofeuille.
