▎ 摘  要

NOVELTY - A reinforced graphene oxide hollow fiber composite film consists of macromolecular knit fiber as supporting layer and graphene or mixture of graphene oxide and polymer resin as separating layer with thickness of 1-4 mm. The knit fiber has inner diameter of 0.5-1 mm. The composite film has pore diameter of 1-500 nm. USE - Reinforced graphene oxide hollow fiber composite film. ADVANTAGE - The reinforced graphene oxide hollow fiber composite film has high transparency and strong hydrophilicity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of the reinforced graphene oxide hollow fiber composite film. A film liquid comprising macromolecule resin, 0-10 %mass of organic additive, 0-4 %mass of inorganic additive and 0.01-10 %mass of graphene oxide in organic solvent is prepared. The prepared liquid is coated on polymeric hollow pipe surface and solidified in a coagulation bath at 20-40 degrees C to form graphene oxide hollow fiber composite membrane.
