  • Graphene preparation method: electrochemical exfoliation.
  • Graphene thickness by AFM: ∼80% 1-3 layers.
  • Sheet size by AFM: 5-10 μm.
  • Oxygen content: 5.5 at.% (C/O-ratio: 17.2).
  • Raman I_D/I_G ratio: 0.25.
  • Sheet resistance: 2 kΩ/sq.
  • Typical properties of films produced thereof (after dilution to 0.1 mg/mL and dry transfer from PTFE-filter):
6 nm film: 91% transmittance, sheet resistance of 24.2 kΩ/sq (as made), 7.9 kΩ/sq (after 30 min, 200 °C), <1 kΩ/sq (conc. HNO3-treatment).
16 nm film: 73% transmittance, sheet resistance of 7.6 kΩ/sq (as made), 1.8 kΩ/sq (after 30 min, 200 °C), <500 Ω/sq (conc. HNO3-treatment).

Mass production of high-quality graphene sheets is essential for their practical application in electronics, optoelectronics, composite materials, and energy-storage devices. Here we report a prompt electrochemical exfoliation of graphene sheets into aqueous solutions of different inorganic salts ((NH4)2SO4, Na2SO4, K2SO4
