▎ 摘　　要

NOVELTY - A graphene thin film manufacturing method involves manufacturing precursor solution, and dispersing graphite oxide powder into solvent, where a graphene thin film is formed by generation of static attraction according to electric potential difference between the precursor solution and a substrate. USE - Method for manufacturing a graphene thin film of a capacitor (claimed). ADVANTAGE - The graphene thin film and the substrate are provided with better adhesive property by avoiding the use of additive and the decreased performance of the graphene, thus achieving better property of the graphene. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a heat supply unit for supplying heat to an injection system (2) a capacitor comprising a grapheme thin film. DESCRIPTION OF DRAWING(S) - The drawing shows a scanning electron microscopy photographic representation of a surface of a graphene thin film.
