NOVELTY - Method for manufacturing block copolymer using graphene film, involves laminating graphene oxide film on substrate, stacking the laminated graphene oxide film and subjecting to self-assembly. USE - The method is used for manufacturing block copolymer for manufacture of metal nanodot. The block copolymer is one of polystyrene-block-poly(methacrylate) (PS-b-PMMA), polystyrene-block-poly(ethylene oxide) (PS-b-PEDs), polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) and polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) (all claimed). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) block copolymer film manufactured by the above-cited method; and (2) method for manufacturing metal nanodot, involves selectively removing a portion of the nano region of the block copolymer film, laminating the metal on mold, lifting-off and removing the block copolymer mold.
