A novel interfacial polymerization approach towards synthesis of graphene oxide-incorporated thin film nanocomposite membrane with improved surface properties

The conventional interfacial polymerization (IP) technique that requires a rubber roller in removing amine aqueous solution is likely to cause uneven distribution of nanomaterials on microporous substrate during thin film nanocomposite (TFN) membrane fabrication. A novel IP technique was developed i...
