▎ 摘  要

NOVELTY - A composite filter membrane comprises a base membrane, and a partially reduced graphene oxide (rGO) deposited on the base membrane, and has a water contact angle of not greater than 15.7 degrees . USE - Composite filter membrane. ADVANTAGE - The composite filter membrane has excellent hydrophilicity, stability, and anti-pollution performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the composite filter membrane, which involves providing a mixed solution containing partially reduced graphene oxide, an organic amine and a surfactant, providing an organic solution containing organic acid chloride, providing the base membrane, contacting the base film with the mixed solution and the organic solution to obtain a dry precursor, and drying.
