NOVELTY - A nylon film comprises 10-10000 ppm carboxyl group, ketone group, and graphene including all amide functional groups on its surface. USE - Nylon film is used as outer resin layer for aluminum pouch film (claimed) for secondary battery. ADVANTAGE - The nylon film has excellent hiding power due to black coloring, by using the surface-treated graphene, and provides excellent slip properties due to a low surface friction coefficient. The aluminum pouch film produced using the nylon film has excellent appearance and moldability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of the nylon film, which involves surface treating the graphene particles with oxygen and ammonia mixed gas plasma, mixing the surface-treated graphene particles with a nylon resin at a concentration of 10-10000 ppm, and forming a film using the mixture; and (2) a secondary battery aluminum pouch film, which comprises an aluminum film layer, an outer resin layer comprising the nylon film, laminated on one surface of the aluminum film layer, and an inner resin layer laminated on the other surface of the aluminum film layer.
