▎ 摘 要
NOVELTY - Forming graphene thin films or functionalized graphene coatings, comprises providing a conducting substrate; and electrophoretically forming the graphene or functionalized graphene using a solution comprising exfoliated graphene sheets or exfoliated functionalized graphene sheets, so that a thin film of graphene or functionalized graphene is formed on the substrate. USE - The method is useful for forming graphene thin films or functionalized graphene coatings. ADVANTAGE - The method provides the graphene thin films, which: are free of detectible pin-hole defects; has less than or equal to 1%/unit area defects/cm2, or has less than or equal to 3% impurities, in which the surface contamination with extraneous impurities is limited to less than or equal to 3% surface coverage; and can cover a continuous area of at least 16 square inches. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene or functionalized graphene thin film, where the thin film is free of detectible pin-hole defects.
