▎ 摘　　要

NOVELTY - A membrane comprises electrospun polyacrylonitrile nanofibers, graphene oxide, and silicon dioxide nanoparticles. The graphene oxide is embedded in the polyacrylonitrile nanofibers forming knots, and the silicon dioxide nanoparticles are on the surface of the polyacrylonitrile nanofibers forming micro-nano protrusions on the nanofibers surface. USE - Membrane e.g. fluid filter used for oil separation (all claimed). Uses include but are not limited to aircraft, watercraft, oil-spill clean-up vehicle, and tankers. ADVANTAGE - The membrane has excellent oil-water separation performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of the membrane; (2) separation of oil; and (3) manufacture of hybrid membrane.
