Thin Film Nanocomposite Solvent Resistant Membrane by Different Functionalized TiO2 Nanoparticles

The interest of Polymeric Solvent Resistant NanoFiltration membranes (SRNFs) are sharply increasing since the fabrication process is cost-effective and reproducible [1-4].Therefore, this study is focusing on Thin Film Nanocomposite (TFN) and Thin Film Composite (TFC) Solvent ResistantNanofiltration Membrane (SRNF) has been developed by conventional interfacial polymerization (IP) method on a porous polyimide (PI) support. TiO2 nanoparticles were usedas inorganic fillers into polyamide chain network. In order to improve compatibilization of nanoparticles inside the polymermatrix two different amine and a chloride chemical functions were employed for surface functionalization of TiO2 nanoparticles. Monoethanolamine (MEOA) andTriethylenetetramine (TETA) imposed as amine functions, while thionyl chloride (TCl) used to chlorination of TiO2nanoparticles. Chlorinated and aminated TiO2 nanoparticleswere incorporated into Isophthaloyl chloride (IPC) organic phase and ethylenediamine (EDA) aqueous phase respectively, prior to IP reaction.
