The invention discloses a kind of graphene ink, graphene substrate utilizes the manufacturing method of the graphene powder of graphene nano manufacture, the graphene layer. Manufacture graphene nano layer applies positive electricity and is depressed into graphite rod or graphene foil as anode and peels off laminated graphene carbon-coating. Anode is at least partially immersed aqueous acid/base electrolyte mixture solution and carries out the fixed ratio for being mixed to prepare acid solution and aqueous slkali. ;The 2016 of copyright KIPO submissions
