NOVELTY - Preparation of soy protein/graphene oxide composite film comprises placing graphite powder, sodium nitrate and sulfuric acid in ice bath, adding potassium permanganate to obtain graphene oxide, dispersing graphene oxide in aqueous solution, mixing with glycerol plasticized modified soybean protein solution, pouring mixture in glass template, and drying at 20-60 degrees C for 24-48 hours. USE - Method for preparing heat resistant soy protein/graphene oxide composite film used for agricultural, chemical industry, food and environment packaging material and disposable container (claimed). ADVANTAGE - The composite film has high heat resistance and good mechanical property.
