▎ 摘　　要

NOVELTY - The composition comprises graphene and fluorinated nanoparticles. The graphene includes non-tubular type graphene material. USE - Composition used for producing film for use as barrier film in an electronic device, preferably organic light emitting device (all claimed). ADVANTAGE - The composition facilitates a barrier film with high flexibility, and excellent moisture and oxygen permeability, and can be prepared in a simple and cost-effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing combination, which involves forming graphene layer, polymer layer, inorganic layer, and a barrier film.
