It is expected that friction forces should cause drastic changes in the structure of rubbed off trace of sp2 bulk graphite (carbon tribolayer or CTL). In this work we studied some properties of CTL. It is found that CTL contains segments of different transmission of light unique to carbon allotropes different from sp2. X-ray diffraction (XRD) pattern, optical absorption spectra reveal a sp2 crystalline structure on the surface of CTL. The Raman spectrum shows distinguished and narrow peaks with symmetrical line shape. Intensity ratio of 2D and G peaks is close to 1 which is characteristic of two-layer graphene. Increased interlayers pacing measured by XRD as well as symmetry of 2D peak of Raman spectra testifies to the presence of turbostratic two-layer sp2 phase at the surface of CTL.
