2D Nanocomposite Membranes: Water Purification and Fouling Mitigation

“…Membrane functionalization with zwitterions grafted onto GO has also been reported in other studies [ 157 , 159 , 212 ]. Besides modification with zwitterions to improve nanosheet migration towards the membrane surface, the application of an electric or magnetic field is another approach to better surface exposure [ 121 , 213 ].…”

A Sm-MOF/GO nanocomposite membrane for efficient organic dye removal from wastewater

“…In this case, combining GO with other nanomaterials to build nanocomposites, purposefully adjusting the properties of the composites to reach the nal separation target, becomes an effective approach to improve membrane performance. 17 Thus, researchers focused on GO and metal-organic framework (MOF) nanocomposites. [18][19][20][21] As a network-like compound with the advantages of an adjustable structure, high porosity and large specic surface area, 22 MOF is constructed by combining a metal center and organic linkers via coordination bonds.…”

Characteristics and Performances of Blended Polyethersulfone and Carbon‐Based Nanomaterial Membranes: Effect of Nanomaterial Types and Air Exposure

“…In this regard, membrane separation technologies including reverse osmosis, nanofiltration, ultrafiltration, microfiltration, membrane distillation, and pervaporation play essential roles in purification of natural waters and wastewaters for drinking water . Membrane processes are favorable compared to other separation processes due to their low capital and operating costs, efficient energy requirement, and ease of operation , . Consequently, research activities on membrane fabrication and how to further improve their separation performances have been a subject of interest in the past few decades.…”

“…Among the above, polyether sulfone (PES) is the most common material to manufacture membranes because of its superior thermal, mechanical, and chemical strengths . Nevertheless, PES is acknowledged as a hydrophobic polymer which is easily able to absorb organic pollutants which cause membrane fouling , , . This leads to decreasing membrane flux and higher maintenance and operation costs.…”

“…Among these nanomaterials, carbon nanotubes (CNTs) and graphene have recently been subjects of interest due to their favorable properties to perform membrane structural enhancements related to surface charge, porosity, and mechanical stability. Therefore, studies on CNTs and graphene impregnated PES membranes have been intensified , , , .…”
