“…The band at 1030 cm −1 corresponds to the asymmetrical stretch vibration peak of Si-O-Si, while the peak at 913 cm −1 can be attributed to a single Al-OH bending band [46,47]. The remaining two bands observed at 3689 and 3624 cm −1 could be due to hydroxyl vibration [46]. These new peaks could be used as indication to confirm the successful incorporation of TiO 2 /HNTs into the PA layer of the TFN membrane.…”

“…Compared with TFC membrane, TFN membrane possesses four additional bands. The band at 1030 cm −1 corresponds to the asymmetrical stretch vibration peak of Si-O-Si, while the peak at 913 cm −1 can be attributed to a single Al-OH bending band [46,47]. The remaining two bands observed at 3689 and 3624 cm −1 could be due to hydroxyl vibration [46].…”

“…By comparing the spectrum of pristine PSF with that of PSF-HNTs substrate, one can see that the latter one has two new bands. The band seen at 1033 cm − 1 represents the asymmetrical stretch vibration peak of Si-O-Si, and the one noticeable at 915 cm − 1 is corresponding to a single Al-OH bending band [47]. Successful incorporation of HNTs into the substrate matrix can be verified by formation of these two new bands.…”

During last few decades, membrane technology has emerged as an efficient technique over conventional methods due to its high removal capacity, ease in operation and cost effectiveness for wastewater treatment and production of clean water. Membrane based separations are commonly based on polymeric membranes because of their higher flexibility, easily pore forming mechanism, low cost and smaller space for installation as compared to inorganic membranes. Commonly employed membrane fabrication phase inversion method has been shortly reviewed in this article. Major limitation of membrane based separations is fouling and polymeric membranes being hydrophobic in nature are more prone to fouling. Fouling is a deposition of various colloidal particles, macromolecules (polysaccharides, proteins), salts etc. on membrane surface and within pores thus impedes membrane performance, reduces flux and results in high cost. Modification of polymeric membranes due to its tailoring ability with nanomaterials such as metal based and carbon based results in polymeric nano-composite membranes with high antifouling characteristics. Nanomaterials impart high selectivity, permeability, hydrophilicity, thermal stability, mechanical strength, and antibacterial properties to polymeric membranes via blending, coating etc. modification methods. Characterization techniques has also discussed in later section for studying morphological properties and performance of polymer nano-composite membranes. Graphical Abstract
