▎ 摘  要

NOVELTY - Usage of graphene oxide nanofiltration membrane under high-operating pressure involves operating graphene oxide nanofiltration membrane at operating pressure of more than 0.2 MPa. The graphene oxide nanofiltration membrane includes a support and a separation layer. The support is an organic/inorganic hybrid membrane containing hydrophilic molecular sieve and polymer. The separation layer is formed by interfacial polymerization of amino-modified graphene oxide and acyl chloride compound. The support and the amino-modified graphene oxide are crosslinked by acyl chloride. USE - Usage of graphene oxide nanofiltration membrane under high-operating pressure.
