▎ 摘　　要

NOVELTY - Graphene/nylon 6 composite film has thickness of 50-200 microns. The composite film comprises 100 pts. wt. graphene/nylon 6 nanocomposite and 0.1-0.5 pts. wt. antioxidant, which are co-melted and casted. The graphene/nylon 6 nanocomposite material consist of nylon 6 and monolayer graphene grafted with nylon 6. The transverse dimension of monolayer graphene grafted with nylon 6 is more than 3 microns. The mass ratio of graphene and nylon 6 is 0.1-0.5:100. USE - Graphene/nylon 6 composite film used for architectural membrane, automotive film and packaging material. ADVANTAGE - The graphene/nylon 6 composite film has high ductility, resistance to ultraviolet, simple and feasible preparation method, effectively absorbs ultraviolet radiation, low graphene content, high cost performance, and is suitable for large-scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing graphene/nylon 6 composite film, which involves: (A) mixing graphene/nylon 6 nanocomposite material and antioxidant uniformly to obtain mixed material; and (B) melting and casting obtained mixed material to obtain final product.
