▎ 摘　　要

NOVELTY - Preparing high stability graphene oxide film comprises (i) preparing graphene oxide; (ii) synthesizing brominated polyphenylene ether film; and (iii) uniformly mixing graphene oxide with crosslinking agent, carrying out ultrasonic treatment, filtering, to obtain brominated polyphenylene ether film, transferring the mixed membrane on water bath steam, to obtain graphene oxide film. USE - The method is useful for preparing high stability graphene oxide film (claimed). ADVANTAGE - The high stability graphene oxide film has high-stability; and is environmentally friendly, and suitable for water treatment.
