▎ 摘  要

NOVELTY - Flexible anti-fouling composite filter membrane comprises mixture of graphene oxide modified basalt fiber, plant nano cellulose, lignin adhesive and polyaspartic acid, which forms a layer of flexible anti-fouling composite fiber film. USE - Flexible anti-fouling composite filter membrane. ADVANTAGE - The flexible anti-fouling composite filter membrane uniformly disperses the graphene oxide modified basalt fiber in the water, so that the excellent characteristics of the inorganic fiber and the organic fiber can be fully exerted. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a flexible anti-fouling composite filter membrane, which involves adding mixture of graphene oxide modified basalt fiber, plant nanocellulose, lignin adhesive and polyaspartic acid to the aqueous solution and stirring for 5-60 minutes as the mother liquor to ensure that it is uniformly mixed, pouring the formed mother liquor into a suction filtration device for dispersion treatment and vacuum filtration at the same time, until a layer of flexible anti-fouling composite fiber membrane with uniform structure is formed on the surface of the large aperture filter membrane frame of the suction filter device.
