BFigure 2. (A) Flake thickness histograms for MONO and QUATTRO products compiled by AFM analysis.
The thickness of a single layer of graphene on an SiO2 substrate, including adsorbed surfactant andwater, is estimated to be approximately 1.1 nm*. (B) Platelet-layer distribution of MONO and QUATTROproducts. MONO Grade material consists of approximately 75% single and double-layer graphene.
Approximately 71% of QUATTRO Grade material is triple layer or greater.
