▎ 摘　　要

NOVELTY - The membrane has a hollow braided tube whose surface is provided with a surface separation layer. Outside diameter of the hollow braided tube is about 0.8-1.9mm. The surface separation layer is made of film-forming polymer material, where thickness of the surface separation layer is about 0.1-0.6 mm. The surface separation layer comprises a graphene and polyvinylidene fluoride component that is utilized as a hydrophobic component. USE - Industrial hydrophobic oleophilic hollow fiber composite membrane. ADVANTAGE - The membrane is simple to manufacture and easy to operate, and has high stability and high durability, and realizes oil water separation function. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a hydrophobic oleophilic hollow fiber composite membrane preparation method.
