▎ 摘　　要

NOVELTY - Graphene nanoribbons are prepared by exposing carbon nanotubes to an alkali metal source in the absence of a solvent, in which exposing opens the carbon nanotubes parallel to their longitudinal axis; and after exposing, adding an electrophile to form functionalized graphene nanoribbons. USE - Method for preparing graphene nanoribbons, preferably functionalized graphene nanoribbons, exfoliated functionalized graphene nanoribbons, and defunctionalized graphene nanoribbons (claimed), used in electronic device. ADVANTAGE - The method is capable of preparing graphene nanoribbons having defect-free structure.
