▎ 摘　　要

NOVELTY - A graphene composition comprises graphene, acid, oxidizing agent and nitrogenous organic compound (I) or (II). USE - Graphene composition is used for manufacturing ccopper (I) ions or copper (II) ions (claimed). ADVANTAGE - The graphene composition has low sheet resistance value and maintains sheet resistance value for long time. DETAILED DESCRIPTION - A graphene composition comprises graphene, acid, oxidizing agent and nitrogenous organic compound of formula N(R11)(R12)(R13) (I) or (II). X21=N or CR21; X22=N or CR22; X23=N or CR23; X24=N or CR24; X25=N or CR25; X26=N or CR26; X27=N or CR27; X28=N or CR28;and R11-R13,R21-R28=1-60C alkyl, 3-10C cycloalkyl, 6-60C aryl, 2-60C heteroaryl (all optionally substituted), or H. At least 3 of X21-X28 is N. An INDEPENDENT CLAIM is included for manufacture of doped graphene (130), which involves doping graphene (110) with graphene acrylate polymer to obtain doped graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view explaining the manufacture of graphene. Graphene (110) Carrier film (120) Doped graphene (130) Target film (140)
