▎ 摘　　要

NOVELTY - Transferring and cleaning graphene film comprises using electrochemical method to peel graphene thin film, obtaining graphene film by peeling off, and adding wetting agent to electrolyte. USE - Method for transferring and cleaning graphene film (claimed) used for storing hydrogen, lithium ion battery, super capacitor or fuel cell, and nano-electronic device, high frequency circuit, photon sensor, electronic gene sequencing and reduces noise. ADVANTAGE - The transfer and cleaning graphene film has strong applicability, low cost and short construction period, and is suitable for industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene film having graphene thin film having good integrity and conductive, migration rate of less than or equal to 9x 104 cm2/(V.S), and graphene thin film as large size graphene film.
