Abstract: The invention provides an apparatus for fluidic exfoliation of a layered material comprising: a housing of circular cross-section defined by a housing wall; a hollow rotor of circular cross-section having a first end and a second end and a wall positioned therebetween arranged concentrically within the housing, wherein the wall of the hollow rotor defines an inner chamber and the space between the wall of the hollow rotor and the housing wall defines an outer chamber, and wherein a fluid flow path is provided between the inner chamber and the outer chamber; a fluid inlet in fluid communication with the inner chamber or the outer chamber; and a fluid outlet in fluid communication with the other of the inner chamber or the outer chamber; wherein the outer chamber has a width such that on passage of a fluid comprising the layered material from the inlet to the outlet through the outer chamber, a shear rate sufficient to exfoliate the layered material may be applied to the fluid comprising the layered material in the outer chamber by rotation of the hollow rotor.
