“…Contact angle values of modified membranes were higher than for unmodified membranes, which indicate that grafting the membrane surface revealed a highly hydrophobic character. Similar phenomena have been observed in previous studies (Kujawa et al 2014a;Wang et al 2016;Yang et al 2017;Hubadillah et al 2018cHubadillah et al , 2019cPolak et al 2021;Saud et al 2021;Twibi et al 2021).…”

“…Metakaolin-based membranes are hydrophilic. Hydrophilic membranes are not suitable to be used for membrane distillation applications (Hubadillah et al 2019a;Twibi et al 2021). Thus, surface modification/grafting is required to obtain hydrophobic properties.…”

“…It was shown that the hydrophilic property of a metakaolin-based flat sheet membrane could be changed into a hydrophobic one by grafting 1H,1H,2H,2H-perfluorodecyltriethoxysilane on the surface of a metakaolin-based flat sheet membrane. The grafting process can be performed by a reaction between OH À groups on the ceramic membrane surface and Si-O-alkyl groups of the silane (Krajewski et al 2006;Khemakhem & Amar 2011;Khemakhem et al 2014;Wang et al 2016;Zuo & Chung 2016;Yang et al 2017;Twibi et al 2021). The surface modifying process can decrease the surface free energy and increase the contact angle of the membranes (Kujawa et al 2017;Shahabadi et al 2017;Yang et al 2017;Hubadillah et al 2018c;Dong et al 2020).…”

“…A metakaolin-based flat sheet membrane is expected to be hydrophilic due to the presence of hydroxyl groups (OH) on its surface. This hydrophilicity is not suitable for the membrane distillation process (Kujawa et al 2014a(Kujawa et al , 2016Hubadillah et al 2019a;Twibi et al 2021). To improve the hydrophobicity of a ceramic membrane, it is necessary to modify the surface of membranes.…”

“…There are three ways commonly used methods of surface modification of polymeric and ceramic membrane, which are chemical modification, surface morphology modification, and combination of chemical and morphology modifications (Khemakhem et al 2013(Khemakhem et al , 2014Usman et al 2021). Among these methods, grafting with perfluoroalkylsilanes (PFAS) is the most commonly applied, especially in membrane distillation applications, because the molecules of the modifiers are covalently attached to the surface as well as inside the porous structure of the ceramic membranes/materials (Kujawa et al 2014a(Kujawa et al , 2014b(Kujawa et al , 2016Abu-Zeid et al 2015;Zuo & Chung 2016;Hubadillah et al 2019a;Twibi et al 2021).…”

Hydrophobic metakaolin-based flat sheet membrane was developed via phase inversion and sintering technique and modified through 1H,1H,2H,2H-perfluorooctyltriethoxysilane grafting agents. The prepared membrane was characterized by different techniques such as XRD, FTIR, SEM, contact angle, porosity, and mechanical strength. Their results indicated that the wettability, structural, and mechanical properties of the prepared membrane confirm the suitability of the material for membrane distillation (MD) application. The prepared metakaolin-based flat sheet membrane acquired hydrophobic properties after surface modification with the water contact angle values of 113.2° to 143.3°. Afterward, the membrane performance was tested for different sodium chloride aqueous solutions (synthetic seawater) and various operating parameters (feed temperature, feed flow rate) using direct contact membrane distillation (DCMD). Based on the findings, the prepared membrane at metakaolin loading of 45 wt.% and sintered at 1,300 °C was achieved the best performance with >95% salt rejection and permeate flux of 6.58 ± 0.3 L/m2 · h at feed temperature of 80 °C, feed concentration of 35 g/L, and feed flow rate of 60 L/h. It can be concluded that further optimization of membrane porosity, mechanical, and surface properties is required to maximize the permeate flux and salt rejection.

Electrospun nanofiber membranes (ENMs) have emerged as a cutting‐edge solution for membrane distillation (MD), recognized for their highly porous and interconnected architecture. This distinctive structure enables them to offer minimal mass transfer resistance, making them exceptionally suited for high‐efficiency membrane‐based separation processes. However, the very porosity that defines their strength also renders them vulnerable to fouling, scaling, and wetting during operation, which in turn compromises their performance. Current research efforts are geared toward overcoming these obstacles by refining the surface design and characteristics of ENMs. This review delves into the latest advancements in surface‐enhanced electrospun nanofiber membranes tailored for MD applications. It discusses the existing gaps in research and provides forward‐looking insights into the future of ENMs, spotlighting the development of membranes with precisely tunable surface attributes for optimized performance.
