NOVELTY - The method involves mixing a graphene oxide and a dimethyl formamide. An anhydrous ethanol is added with an ultrasonic treatment. A base film is formed with the ultrafiltration. A soaking liquid is provided with the base film. A filter film is formed using air aeration stir process. The ultrasonic treatment is obtained an amidogen modified graphene oxide, where the amidogen modified graphene oxide volume ratio is 9. A trimethylolpropane amidogen alkyl solution is mixed with a hydrochloric that is added to a sodium hydroxide solution. A cleanwater flushing is carried on a sodium azide solution. USE - Micro-filter film preparation method for amine modified graphene oxide. ADVANTAGE - The method enables providing high machinery intensity and better hydrophilicity.
