We use microfluidization technique to exfoliate few layers graphene (MF flakes) from graphite into a water-based dispersion. Microfluidizer can pass fluids through micro-channels (diameter, d 100 μm) at high pressure (up to 209 MPa), 35 which generates liquid velocities of 400 m s −1 and several order of magnitudes higher shear rates (10 8 s −1 ) 36 than conventional rotor-based or
