Abstract:
A system for the exfoliation of a layered material is described, comprising in combination: an exfoliation station ( 14 - 22 ) operating on a volume of a dispersion of a layered precursor material, including a wet-jet milling device ( 10 ); and a collecting station ( 30, 40 ), located downstream of the exfoliation station ( 14 - 22 ), operating on a volume of a dispersion of the at least partly exfoliated material, in which the exfoliation station ( 14 - 22 ) and the collecting station ( 30,   40 ) are connected to each other through a fluid communication path ( 20 ) along which there are interposed flow regulating means ( 50 ) adapted to assume a first operating configuration in which the communication path ( 20 ) between the exfoliation station ( 14 - 22 ) and the collecting station ( 30, 40 ) is discontinued, where the exfoliation station ( 14 - 22 ) is adapted to subject a volume of dispersion of layered precursor material to a predetermined number of wet jet milling cycles; and a second operating configuration in which the communication path ( 20 ) between the exfoliation station ( 14 - 22 ) and the collecting station ( 30, 40 ) is continuous, where the exfoliation station ( 14 - 22 ) is adapted to convey a volume of previously milled dispersion including at least partly exfoliated material to the collecting station ( 30, 40 ) and is placed in communication with a supply chamber ( 12 ) to be fed with a further volume of a dispersion of layered precursor material that has to be exfoliated.

Claim (Index 9):
A method for exfoliating a layered material, comprising the steps of:\n providing a dispersion of a layered precursor material; and, iteratively exposing a volume of said dispersion of layered precursor material to a predetermined number of wet-jet milling cycles in an exfoliation station; subsequently, conveying the dispersion volume previously exposed to milling and including material at least partially exfoliated to a collecting station; and extracting an amount of exfoliated material from the dispersion volume conveyed at the collecting station, in which the fluid communication between the exfoliation station and the collecting station is alternately regulated between a first operating phase in which said communication is discontinued, during which a volume of a dispersion of a layered precursor material is exposed to a predetermined number of wet-jet milling cycles at the exfoliation station and an amount of exfoliated material is extracted from a volume of a dispersion previously exposed to milling and including material at least partially exfoliated at the collecting station; and a second operating phase in which said communication is continuous, whereby a volume of a dispersion previously exposed to milling and including at least partially exfoliated material is conveyed from the exfoliation station towards the collecting station, and a further volume of a dispersion of a layered precursor material is fed to the exfoliation station.
