This is a consequence of the energy redistribution of valence electrons due to rupture of the interatomic bond by dispersing nanoscale materials to which the number of surface atoms with broken bonds becomes comparable to the number of atoms in the nanoparticles. Revealed a decrease in the intensity SKa - bands of graphene nanosheets in the high-energy region compared with the spectrum of oxidized graphene nanosheets , which is associated with a decrease in the distance between the graphene layers from 0.75 nm to 0,337 nm and an increase in the overlap between the orbitals rozorientovnih corrugated graphene nanosheets . It has been established that the interaction of oxygen with electrons that occupy orbitals oxidized graphene nanosheets , leads to rise in a direction of attracting force to the axis , resulting in corrugation of the graphene layers.
