Deformation of Graphene Layers and Phase Transformations in the Hydrogen Nanophase Intercalated in Them

The intercalation of a high-density molecular hydrogen nanophase into graphene nanostructures has been studied. The deformation of the graphene layers in the material and the phase transformations of intercalated hydrogen, in particular, the thermoelastic equilibrium of the system, is considered. The possibility of intercalating the nanophase of molecular hydrogen into hydrogenated graphite nanofibers is justified theoretically.
