▎ 摘　　要

NOVELTY - The method involves adding graphene oxide and chlorinated hydroxylamine to water in a mass ratio of 2:1-1:3.5, adjusted to pH 8-11, and then heated to reflux for 2-48 hours at 40-100degreesC. A hydroxylamine functionalized graphene dispersion is obtained. The hydroxylamine-functionalized graphene is supported on the substrate by the method of suction filtration for membrane formation, and the hydroxylamine-functionalized graphene membrane is obtained by washing with water for many times after the suction filtration is completed. USE - Preparation method of hydroxylamine functional graphene film use in gas-water separation. ADVANTAGE - The hydroxylamine functional graphene film has excellent permeability and non-permeability, and can be prepared in simple and cost-effective manner. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic vacuum degree of the hydroxylamine functional graphene film with time change trend graph. (Drawing includes non-English language text)
