ZnO/PES composite membranes were fabricated by phase inversion method using DMAc as a solvent. The structure of ZnO was investigated TEM, SEM, XRD, and TGA. TEM images nanoparticles well-defined, small, spherically shaped with agglomerated particles 50 nm. SEM XRD results an indication that present in the prepared composites membranes. Contact angle measurements used to investigate surface structures amount on PES varied obtain optimal performance terms pure water flux, flux recovery,...
The silver-zinc oxide (Ag-ZnO) polyamide thin film composite (PA-TFC) membrane was prepared by interfacial polymerization. Ag-ZnO/PA-TFC characterized attenuated total reflectance fourier-transform infrared spectroscopy (ATR-FTIR) for functional groups and contact angle surface hydrophilicity. further Scanning Electron Microscopy (SEM) Atomic Force (AFM) morphology roughness, respectively. performance of the fabricated investigated using pure water flux, permeability, rejection, flux...
Three different types of nanoparticles were synthesised in this study, viz silver (Ag), zinc oxide (ZnO) and titanium dioxide (TiO2) using chemical methods. These materials then characterised Transmission Electron Microscopy (TEM), Fourier Transform Infra-Red Spectroscopy (FTIR), Ultraviolet Visible (UV-Vis) Thermal Gravimetric Analysis (TGA). The also tested for anti-bacterial activity. TEM showed that the particles nano-size range (1 – 100 nm). FTIR UV-Vis absorption bands nanoparticles,...
