▎ 摘  要

NOVELTY - Preparing graphene oxide film, comprises (1) dispersing the nano metal particles in deionized water to obtain a well-dispersed nano metal solution, (2) adding the well-dispersed nano metal solution into the graphene oxide slurry to make it fully contact to obtain a graphene oxide aqueous slurry compounded by metal elements, and (3) coating the graphene oxide aqueous slurry compounded with metal elements on the substrate and drying to obtain a graphene oxide film. USE - The method is useful for preparing graphene oxide film, which is useful in the airbag structure of a vehicle and for inhibiting graphene self-supporting film thermal expansion. ADVANTAGE - The method effectively inhibits the expansion of the graphene from the supporting film in the heat treatment, improves heat treatment yield, at the same time, it can improve the preparation yield and performance of the product.
