▎ 摘　　要

NOVELTY - Film comprises atomic layer, and structure in which the graphene quantum dot is dispersed and spread on one side or both sides of the atomic layer, where graphene quantum dot is single crystalline structure of flake type. The diameter of the graphene quantum dot is 5-25 nanometer. USE - Film. ADVANTAGE - The film has cost reduction effect, oxygen permeability and/or moisture transmission degree, excellent rigidity, excellent antibacterial effect and integrity of food, reduces the structural stiffness, prevents penetration of the foreign material, and improves durability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for manufacturing film, which involves irradiating ultrasound in mixture, mixing reduction graphene oxide (reduced grapheneoxide, rGO) and solvent; filtering the mixture in which ultrasound is irradiated through the dialysis and manufacturing the graphene quantum dot; and dispersing the manufactured graphene quantum dot into the atomic layer one side or both sides; and (2) a food packaging material, which comprises film.
