▎ 摘　　要

NOVELTY - A high-barrier antistatic graphene/polymer nanocomposite sheet/film has nano sphere or crystal structure having size of 300 nm, and comprises 100 parts mass polymer matrix resin, 0.03-0.05 part mass graphene, and 0-1.5 parts mass compatibilizer. The oxygen permeability of graphene/polymer nanocomposite sheet/film is 2.32-5.69 cc/m2 per day, preferably 2.35 plus minus 0.3 cc/m2 per day, and surface resistivity of 1010-107 Omega . USE - High-barrier antistatic graphene/polymer nanocomposite sheet/film (claimed). ADVANTAGE - The high-barrier antistatic graphene/polymer nanocomposite sheet/film has excellent gas barrier property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of high-barrier antistatic graphene/polymer nanocomposite sheet/film.
