NOVELTY - A nylon film comprises graphene containing all of carboxyl, ketone, and amide functional groups on the surface at a concentration of 10-10000 ppm. The graphene has an average diameter of 0.0001-0.5 μ m. USE - Nylon film used for forming outer resin layer for aluminum pouch film used as exterior material for packaging secondary battery (all claimed) e.g. lithium secondary battery. ADVANTAGE - The nylon film has excellent rupture strength, pinhole resistance, gas barrier property, heat resistance, cold resistance, mechanical strength, black expression property, hiding power, and slip property due to a low surface friction coefficient. The aluminum pouch film has excellent appearance and moldability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: manufacture of nylon film, which involves (i) surface-treating the graphene particles with oxygen and ammonia mixed gas plasma, (ii) mixing the surface-treated graphene particles with a nylon resin at a concentration of 10-10000 ppm and (iii) forming a film using the mixture; and aluminum pouch film, which comprises a layer of aluminum film, an outer resin layer containing the nylon film laminated on one surface of the aluminum film layer and an inner resin layer laminated on other surface of the aluminum film layer.
