NOVELTY - Production of high-mechanical property graphene oxide-polyetheramine composite film involves ultrasonically dispersing graphene oxide in distilled water, adding obtained uniform dispersion of graphene oxide to a vacuum filtration apparatus, vacuum-filtering using cellulose membrane, forming graphene oxide thin film, injecting aqueous polyetheramine solution with a syringe, continuing filtration, removing thin film from the filtration apparatus, heating, washing with a solvent, and drying. USE - Production of high-mechanical property graphene oxide-polyetheramine composite film (claimed). ADVANTAGE - The method enables economical production of graphene oxide-polyetheramine composite film with high mechanical property, tensile strength and elastic modulus, by simple process.
