▎ 摘　　要

NOVELTY - N-doping method of graphene involves forming graphene oxide by oxygen-plasma treatment of graphene, transferring graphene oxide to another graphene to form bilayered structure of graphene oxide/graphene, and doping resulting structure with an amine-containing functional group. USE - N-doping method of graphene for N-doped graphene oxide/graphene bilayer structure (claimed) for transparent electrode and sensor. ADVANTAGE - N-doped graphene oxide/graphene bilayer structure having excellent thermal stability and flexibility is produced by doping method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for N-doped graphene oxide/graphene bilayer structure.
