“…In recent years, the mesoporous powders have been incorporated into various commercial polymeric matrixes to expand the applicability of mesoporous materials for reverse osmosis, ultrafiltration, nanofiltration, and desalination. [107][108][109][110][111][112][113][114][115] Compared with the pristine polymer membranes, the hybrid composite thin films possess improved hydrophilicity and adsorption capacity and other functionalities depending on the inherent properties of the doped mesoporous materials. In general, mesoporous particles with different pore structures and chemical compositions were fixed in PVDF, 107 polysulfone (PSU), [108][109][110][111] poly(ether imide) (PEI), 112 and polyamide (PA) 113 via either physical infusion or chemical interfacial polymerization process, demonstrating superior removal efficiency for contaminants in water.…”

Porous materials have become a burgeoning research interest in materials science because of their intrinsic porous characteristics, versatile chemical compositions, and abundant functionalities. Recently, inspired by natural superwetting surfaces originating from the cooperation of surface energy and surface geometry, porous membranes with special wettabilities are finding emerging opportunities associated with a wide variety of environmental and energy-related applications. This review will present an overview of the state-of-the-art research on the designed fabrications and applications of superwetting porous membranes based on zeolites, metal-organic frameworks (MOFs), porous organic materials (POMs), and mesoporous materials. General synthetic strategies for the fabrication of porous membranes (e.g., hydrothermal/solvothermal crystallization, interfacial polymerization, electrospinning, etc.), and principles for tuning the wettability of porous membranes through surface energy modulation are introduced. Furthermore, their emerging applications as oil-water separation membranes, lithium-ionbattery separators, self-cleaning layers, and anticorrosion coatings are demonstrated. Finally, we emphasize on future perspectives regarding the development of superwetting porous membranes for practical applications.

“…Interfacial polymerization was carried out in the oven for 3 minutes under the constant temperature of 60ºC. The monomer solution was influenced only on the top surface of the membrane in all processes of polyamide layer synthesis [5,18]. The membrane was soaked with distilled water to remove the surplus solvent in case of the chemically crosslinked membranes.…”

Forward Osmosis (FO) is a technique that requires less power consumption compared to other membrane techniques. FO is significant for its fouling resistance rate, energy consumption, high recovery rate, water flux and scourable. The FO membrane is fabricated by successive steps namely phase inversion via immersion precipitation followed by interfacial polymerization under suitable parameters. The application of FO in various fields can be enhanced by overcoming the limitations. This study shows the approaches of membrane fabrication for FO technique, applications, advancement in the current industries with limitations and overcoming solutions.

“…Silica nanoparticles have chemical compatible and the mechanical stability needed for preparation of polymeric membrane, and their structure can be changed by chemical functionalization [ 25 ]. Thus, SBA-15 ordered mesoporous silica was used as nanofiller to improve the water permeability of a polymer matrix [ 26 ]. A higher compatibility and adhesion between inorganic nanoparticles and polymer matrix were obtained by functionalization with amine groups of silica surface in the presence of (3-aminopropyl) triethoxysilane (APTES) as coupling agent.…”

Nanofiltration Composite Membranes Based on KIT-6 and Functionalized KIT-6 Nanoparticles in a Polymeric Matrix with Enhanced Performances

The nanofiltration composite membranes were obtained by incorporation of KIT-6 ordered mesoporous silica, before and after its functionalization with amine groups, into polyphenylene-ether-ether-sulfone (PPEES) matrix. The incorporation of silica nanoparticles into PPEES polymer matrix was evidenced by FTIR and UV–VIS spectroscopy. SEM images of the membranes cross-section and their surface topology, evidenced by AFM, showed a low effect of KIT-6 silica nanoparticles loading and functionalization. The performances of the obtained membranes were appraised in permeation of Chaenomeles japonica fruit extracts and the selective separation of phenolic acids and flavonoids. The obtained results proved that the PPEES with functionalized KIT-6 nanofiltration membrane, we have prepared, is suitable for the polyphenolic compound’s concentration from the natural extracts.
