Nanotribological Properties of Graphite Intercalation Compounds: AFM Studies

Figure 9

AFM height images of the surface scratches on the pristine graphite flake (a) and corresponding wear scars (b), GIC/TOAB flake at −1.5 V (c) and corresponding wear scars (d), GIC/TOAB flake at −2 V (e) and corresponding wear scars (f), and GIC/TOAB flake at −2.5 V (g) and corresponding wear scars (h). The thicknesses of these flakes were ~30 nm.
