“…Final experiments confirmed the strong adhesion of nanosheets to the membrane surface, and showed that no nanosheets were detached [ 203 ]. By contrast in the previous study of Abdikheibari et al [ 210 ], aminated BN nanosheets were embedded in a PPA thin layer, and achieved flux improvement and enhanced fouling resistance of 13.4% and 5.2%, respectively. These results highlight the importance of surface exposure of nanosheets for stacked TFC membranes [ 203 ].…”

In this study, the characteristics of different types of nanosheet membranes were reviewed in order to determine which possessed the optimum propensity for antifouling during water purification. Despite the tremendous amount of attention that nanosheets have received in recent years, their use to render membranes that are resistant to fouling has seldom been investigated. This work is the first to summarize the abilities of nanosheet membranes to alleviate the effect of organic and inorganic foulants during water treatment. In contrast to other publications, single nanosheets, or in combination with other nanomaterials, were considered to be nanostructures. Herein, a broad range of materials beyond graphene-based nanomaterials is discussed. The types of nanohybrid membranes considered in the present work include conventional mixed matrix membranes, stacked membranes, and thin-film nanocomposite membranes. These membranes combine the benefits of both inorganic and organic materials, and their respective drawbacks are addressed herein. The antifouling strategies of nanohybrid membranes were divided into passive and active categories. Nanosheets were employed in order to induce fouling resistance via increased hydrophilicity and photocatalysis. The antifouling properties that are displayed by two-dimensional (2D) nanocomposite membranes also are examined.

“…Membrane-based separation offers a scalable, economically and environmentally friendly tool for numerous applications, e.g., biochemical and pharmaceutical processing, water purication, and wastewater treatment. [1][2][3][4][5] Although the interest in developing high-performance membranes has been growing from diverse inorganic, organic, and composite materials, [6][7][8][9][10][11][12][13] a longstanding goal in membrane technology is still to pursue an ideal membrane with a high permeance, good selectivity and strong fouling resistance.…”

AB Nm embrane with ad istinct nanoconfinement effect toward efficient ethylene/ethane separation is presented. The horizontal and inclined self-assembly of 2D BN nanosheets endowt he BN membrane with abundant percolating nanochannels,a nd these nanochannels are further decorated by reactive ionic liquids (RILs) to tailor their sizes as well as to achieve nanoconfinement effect. The noncovalent interactions between RIL and BN nanosheets favor the ordered alignment of the cations and anions of RIL within BN nanochannels, which contributes to afast and selective ethylene transport. The resultant membranes exhibit an unprecedented separation performance with superhigh C 2 H 4 permeance of 138 GPU and C 2 H 4 /C 2 H 6 selectivity of 128 as well as remarkably improved long-term stability for 180 h, outperforming reported state-of-the-art membranes.

Thin film nanocomposite nanofiltration membranes from amine functionalized-boron nitride/polypiperazine amide with enhanced flux and fouling resistance

Abstract: Thin film composite (TFC) nanofiltration (NF) membranes typically used for drinking water treatment applications are susceptible to fouling by natural organic matter (NOM) which adversely affects the permeation and separation efficacy.
