  • Patent number: 11634329
    Abstract: Nanoplatelets are prepared from a 3D layered material by: providing a dispersion of the 3D layered material, pressurising the dispersion, rapidly depressurising the dispersion to create shear forces that exfoliate the 3D layered material into nanoplatelets; and/or providing a dispersion of the 3D layered material, forming a first flow of the dispersion along a first flowpath in a first direction, forming a second flow of the dispersion along a second flowpath in a second direction by reversing the first flow or by forming the second flow in a second flowpath, wherein the second flowpath is substantially reverse and non-coaxial with the first flowpath, whereby shear forces between material in the first flowpath and material in the second flowpath exfoliate the 3D layered material into nanoplatelets. Also provided are apparatuses for carrying out the invention and nanoplatelets obtained by the invention.
