Abstract

Novel hybrid nanostructures (HNS) comprising of a mussel-inspired polymer coated metal/metal oxide (M/MO)–carbon nanotubes (CNTs), were successfully synthesized and used to fabricate Thin Film Nanocomposite (TFN) membranes for desalination applications. For comparison, four different M/MO (Aluminium...
