▎ 摘　　要

NOVELTY - High flux and environmentally friendly performance poly (m-phenylene isophthalamide) (PMIA) mixed matrix ultrafiltration membrane comprises poly-phenylene isophthalamide and graphene oxide. The mass ratio of the poly-m-phenyleneisophthalamide and the oxidized graphite alkene is 0.05-0.2: 83.3-83.45. USE - The ultrafiltration membrane useful for preventing pollution (claimed). ADVANTAGE - The membrane: has high flux and anti-pollution performance; and improves the circulating utilization rate of the film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the high flux and environmentally friendly performance PMIA mixed matrix ultrafiltration membrane.
