“…Metal cations used for membrane preparation used were non-toxic, environment friendly and cheap [188][189][190][191][192][193][194]. Their results revealed that when metal cations are incorporated within GO, resulted membranes were flexible with metal cations having no effect on GO membranes mechanical stability.…”

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

“…As previously mentioned, MWCNTs-COOH exhibited the strongest negative charge of the three MWCNTs. According to the literature [39,46], the surface of BSA molecules was also negatively charged. The electrostatic interaction between the negatively charged membrane and BSA molecules made it more difficult for BSA molecules to permeate through the CNT layer [42].…”

“…In order to address the issue of biofouling of hydrophobic porous membranes, three main research directions are currently under investigation. In-situ modification consists in blending the hydrophobic polymer with an appropriate amphiphilic copolymer in a common solvent, before inducing phase inversion of the polymeric system [1][2][3][4]. This method is direct (formation and modification all at once) but can lead to major changes of the membrane structure, and so to modifications of arising properties, which may not be on target.…”
