The article is devoted to the synthesis of ceramic membranes based on silicon carbide and the study of their mechanical, electrical, and antibacterial properties. SiC-based ceramic membranes have a few advantages, namely high surface hydrophilicity, good water permeability and negative surface charge, which leads to better performance during their operation. The effect of carbonate type and addition of liquid glass on the physicochemical properties of ceramic membranes was investigated using diffraction analysis and scanning electron microscopy. It was found that regardless of the carbonate type, only two phases can be identified: the main phase in the original mixture is silicon carbide and an additional phase added to the mixture is corundum. The transport properties obtained (9.03–18.66 cm3/(min·cm2)), and the results of electron microscopy indicate the macroporosity of ceramic membranes based on silicon carbide (13–20 µm). Ceramic membranes of high strength (16.3–46.8 MPa) were obtained. Studies on antibacterial properties have shown that SiC-based ceramic membranes do not exhibit antibacterial properties. The additional modification of ceramic membranes with titanium oxide has given ceramic membranes based on silicon carbide antibacterial properties, as evidenced by the inhibition of the growth of gram-negative bacteria, the effectiveness of which depends on the number of selective layers based on TiO2 applied. The results of this study are useful to enrich the knowledge of the production of silicon carbide membranes and are aimed at the future research and development of selective membranes (micro- and ultrafiltration) based on them.

“…[4][5][6][7][8][9][10] However, the trade-off between permeability and selectivity was still the main limitation for further implementations of polymeric nanofiltration membranes. [11,12] Aramid nanofibers (ANFs), as typical onedimentional organic nanomaterials consisting of poly(paraphenylene terephthalamide) (PPTA) chains, were first produced by Kotov et al who reported fiber bundles with a diameter of 3-30 nm. [13] Recently, ANFs have drawn increasing interest because of their outstanding properties, such as high mechanical strength and chemical stability, especially in a wide range of solvents and high temperatures.…”

Aramid nanofibers (ANFs), as promising organic nano building blocks for their high mechanical strength and thermal stability, are widely applied to fabricate energy‐efficient membranes for ionic and molecular sieving in aqueous solutions. However, the existing ANFs often have small diameters, limiting the permeability of the resulting membranes. Here, the ANFs with a diameter in the hundred‐nanometer scale are fabricated through a progressive protonation process, in which dimethylformamide as a secondary deprotonation solvent is added into dimethyl sulfoxide to provide a mild deformation environment. Then, the deformed ANFs are applied to prepare membranes with a larger pore size distribution and higher surface charge. Notably, the water flux of the resulting membranes can reach up to 410 L m−2 h−1 bar−1, which is 40 times higher than commercially available nanofiltration membranes and much higher than currently reported ANF‐based membranes. Impressively, these membranes with super‐stable nanochannels maintain a high water flux of over 194 L m−2 h−1 bar−1 in a wide range of pH values from 4 to 10 and show excellent long‐term durability over 120 h. The application of deformed ANFs provides a new and promising approach for designing the next generation nanofiltration membranes which balance the trade‐off between permeability and selectivity.

“…In addition to the urgent need for increased attention directed towards human behavioral change and for stronger legislation with respect to the conservation and protection of fresh water systems, technological innovations have the potential to help enhance water security ( Connor, 2015 ;UNESCO, 2018 ;Vörösmarty et al, 2010 ). Thanks to its high energy-efficiency, modularity and low cost, membrane technology has been displacing other separation technologies for water treatment, such as distillation, and continues to get increased industrial attention ( El Fadil et al, 2023 ;Sholl and Lively, 2016 ;Elimelech and Phillip, 2011 ;Jones et al, 2019 ).…”
