Beschreibung
Zusammenfassung:	Described herein are methods for continuous production of an exfoliated two-dimensional (2D) material comprising passing a 2D material mixture through a convergent-divergent nozzle, the 2D material mixture comprising a 2D layered material and a compressible fluid. The method of the present disclosure employs physical compression and expansion of a flow of high-pressure gases, leaving the 2D layered material largely defect free to produce an exfoliated 2D layered in a simple, continuous, and environmentally friendly manner. La présente invention concerne des procédés de production continue d'un matériau bidimensionnel (2D) exfolié comprenant le passage d'un mélange de matériaux 2D à travers une buse convergente-divergente, le mélange de matériaux 2D comprenant un matériau 2D en couches et un fluide compressible. Le procédé de la présente invention utilise la compression et la dilatation physiques d'un flux de gaz à haute pression, laissant le matériau 2D en couches dans une large mesure exempt de défauts pour produire un matériau 2D exfolié en couches d'une manière simple, continue et respectueuse de l'environnement.
