Surface modification of thin film composite polyamide membrane using atomic layer deposition method

TiO2 nanocomposite based polymeric membranes: A review on performance improvement for various applications in chemical engineering processes

“…Polyimide provides excellent gas permeability, thermal and mechanical stability, and high chemical resistance. Different TiO 2 immobilized thin film membranes were investigated for increasing surface hydrophilicity of membrane [67,[69][70][71][72]. Peyravi et al [73] developed thin film nanocomposite nanofiltration membranes in which in situ interfacial incorporation of TiO 2 nanoparticles was applied to produce the thin layer along with fabrication of copolyamide network on a polyimide support.…”

Hybrid Membranes of Polyamide Applied in Treatment of Waste Water

“…In cross section, it is still possible to observe a variation in pore size throughout its thickness, with pores of spherical shape and evenly distributed. This difference in morphology on the cross section of the membrane is responsible for the permeability and selectivity of the membrane 50,51 . The addition of 10% of CaCl 2 in the preparation of pure PA6 membrane caused an increase in the amount of the pores and uniformity distribution of them on the surface and cross-section of these membranes.…”

Preparation of thin-film composite nanofiltration membranes with improved antifouling property and flux using 2,2′-oxybis-ethylamine

“…But post-surface treatment could increase the penetration resistance leading to flux decrease. Covalent bonding of hydrophilic groups is another attempt to improve fouling resistant performance [16][17][18][19]. Addition of monofunctional structure (o-Aminobenzoic acid-triethylamine salt) into the ingredient of interfacial polymerization, then coating of cross-linked PEG can improve the flux and antifouling performance of membranes according to Ho's work [20].…”
