▎ 摘　　要

NOVELTY - Filling holes of graphene thin film, comprises (a) preparing graphene thin film, (b) filling aromatic compound or nano-carbon material in the holes present in graphene thin film, and (c) combining aromatic compound or nano-carbon material with the holes by heat treating the holes filled graphene thin film. The nano-carbon material includes at least one of fullerene, carbon nanotube, carbon black and nano-diamond. The aromatic compound includes at least one of aromatic compound having at least two benzene rings and their derivatives. USE - The method is useful for filling holes of graphene thin film (claimed). ADVANTAGE - The method minimizes defects in the graphene thin film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene thin film having holes filled by the above method.
