  • Scalable process for producing exfoliated defect-free, non-oxidised 2-dimensional materials in large quantities
    Patent number: 10304937
    Abstract: A process for exfoliating untreated 3-dimensional material to produce a 2-dimensional material, said process comprising the steps of mixing the untreated 3-dimensional material in a liquid to provide a mixture; applying shear force to said mixture to exfoliate the 3-dimensional material and produce dispersed exfoliated 2-dimensional material in solution; and removing the shear force applied to said mixture, such that the dispersed exfoliated 2-dimensional material remains free and unaggregated in solution.
    Type: Grant

    Assignee: The Provost, Fellows, Foundation Scholars, and the Other Members of Board, of the College of the Holy and Undivided Trinity of Queen Elizabeth Near Dublin
    Inventors: Jonathan Coleman, Keith Paton
  • TWO-DIMENSIONAL MATERIALS
    Publication number: 20170240428
    Abstract: A method of preparing a 2D material (e.g. graphene or of boron nitride), the method comprising: (i) selecting a fluid comprising the 2D material dispersed in a solvent; (ii) using a filtration device to remove solvent from the fluid and increase the concentration of 2D material in the fluid, wherein the fluid suitably includes a surfactant, which may be sodium cholate or sodium dodecylbenezenesulphonate and wherein the filtration device is suitably a cross-flow filtration device.
