▎ 摘　　要

NOVELTY - Manufacture of magnetic graphene mixed matrix membrane involves dissolving 1-5 pts. wt. microporous organic polymer powder in 40-50 pts. wt. solvent, magnetically stirring for 3-6 hours, filtering with needle filter having size of 0.2-0.8 mu m, adding 0.005-0.02 pt. wt. magnetic graphene powder, ultrasonically stirring for 6-12 hours, coating on a polytetrafluoroethylene film to thickness of 80 mu m, drying at room temperature for 24 hours to remove solvent, and drying in vacuum oven. USE - Manufacture of magnetic graphene mixed matrix membrane (claimed) for separating oxygen and nitrogen gases. ADVANTAGE - The magnetic graphene mixed matrix membrane having excellent magnetic characteristics, permeability and selectivity is produced. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for magnetic graphene mixed matrix membrane.
