FIELD: chemistry.
SUBSTANCE: invention relates to chemical industry and nanotechnology. Plurality of carbon nanotubes is exposed to a source of alkali metal in presence of an aprotic solvent and in absence of protic solvent. Carbon nanotubes opened in a direction parallel to their longitudinal axes are obtained. To obtain non-functionalised graphene nanoribbons, opened carbon nanotubes are exposed to a protic solvent. To obtain functionalised graphene nanoribbons, opened carbon nanotubes are exposed to an electrophile. Obtained graphene nanoribbons have specific conductivity of 0.1–9,000 S/cm.
EFFECT: invention can be used for production of composites and fibres for displays, deicing circuits, gas-permeable composites and screens.
