The investigation paper ‘Thin film nanocomposite (TFN) membranes modified with polydopamine coated metals/carbon-nanostructures for desalination applications’ will be published in Elsevier journal Desalination.
Summary
Novel hybrid nanostructures (HNS) comprising of a mussel-impressed polymer coated metal/metal oxide (M/MO)-carbon nanotubes (CNTs), ended up successfully synthesized and employed to fabricate Slim Movie Nanocomposite (TFN) membranes for desalination purposes. For comparison, 4 diverse M/MO (Aluminium oxide-Al2O3, Iron oxide-Fe2O3, Titanium dioxide-TiO2 and Silver-Ag) nanoparticles (NPs) ended up in situ synthesized/loaded on the floor of CNTs, and the resultant HNS ended up more coated with a skinny polymeric film of polydopamine (PDA). An intermediate layer of HNS was then deposited on a PES substrate membrane and an interfacial polymerization (IP) method was carried out to render a polyamide (PA) skinny layer previously mentioned the intermediate layer. Each HNS and TFN ended up characterised making use of diverse characterization applications, such as fourier transforms infrared spectroscopy (FTIR), zeta likely (ZP), X-ray diffraction (XRD), raman spectroscopy, scanning electron microscopy (SEM), electrical power-dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS), thermogravimetric examination (TGA), floor hydrophilicity/hydrophobicity, and the overall performance of nanofiltration (NF) membranes ended up evaluated from monovalent and divalent salts methods. The fabricated TFN-NF membranes experienced higher overall performance in terms of their permeation properties in contrast to the skinny film composite TFC membrane, when protecting their selectivity from both monovalent and divalent salts methods with only insignificant variation based on the integrated HNS employed to get ready the TFN.
