General description

  • Graphene preparation method: electrochemical exfoliation.
  • Graphene thickness by AFM: 80%, 1-3 layers.
  • Sheet size by AFM: Few micrometers
  • Oxygen content: 7.5% (by XPS) (C/O-ratio: 12.3).
  • Raman I_D/I_G ratio: 0.4.
  • Sheet resistance: 4.8 kΩ/sq.
  • Typical properties of films produced thereof (after dry transfer from PTFE-filter):
15 nm film: 85% transmittance, sheet resistance of 16 kΩ/sq (as made), 4.1 kΩ/sq (after 30 min, 200 °C), <1 kΩ/sq (conc. HNO3-treatment).
25 nm film: 73% transmittance, sheet resistance of 8 kΩ/sq (as made), 2.4 kΩ/sq (after 30 min, 200 °C), <1 kΩ/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
