In response to the phenomenon of interlayer transport channel swelling caused by hydration oxygen-containing functional groups on GO membrane surface, a moderate heat treatment method was employed controllably reduce graphene oxide (GO) and prepare reduced composite nanofiltration (mixed cellulose (MCE)/ethylenediamine (EDA)/reduced GO-X (RGO-X)). The associations different temperatures with hydrophilicity, structure, permeability dye/salt rejection properties membranes were systematically explored. results indicated that partially eliminated after treatment, hydrophilicity weakened. This effectively weakened between water molecules inhibited oxidized membrane. dye desalination test, MCE/EDA/RGO exhibited an ultra-high rate over 97% for methylene blue (MB) molecules. addition, increased structural defects promoted fast passage via pure flux testing, remained above 46.58 Lm−2h−1bar−1, while salt relatively low.

In recent years, graphene oxide (GO)-based two-dimensional (2D) laminar membranes have attracted considerable attention because of their unique well-defined nanochannels and deliver a wide range molecular separation properties fundamentals. However, the practical application 2D GO layered suffers from instability in aqueous solutions as interlayer d-spacing is prone to expansion caused by hydration effect. this study, effects ethylenediamine (EDA) addition amount on structure, crosslinking mechanism performance were investigated systematically, membrane was evaluated using water permeability dye/salt rejection tests. The experimental results show that amine groups EDA chemically bond with hydroxyl functional group (O=C–OH) after intercalation, evident Fourier transform infrared spectroscopy (FTIR) X-ray photoelectron (XPS). By further controlling intercalated EDA, as-prepared composite nanoscale-tuned promising for downstream applications. demonstrated nanofiltration scenario, crosslinked has enhanced over five times better dye rate 96% compared pure membranes. These findings highlight facile strategy tuning amounts reactive intercalants.

The applications of polymeric membranes have grown rapidly compared to traditional separation technologies due their energy efficiency and smaller footprint. However, potential is not fully realized due, in part, heterogeneity, which results a "permeability–selectivity" trade-off for most membrane applications. Inspired by the intricate architecture excellent homogeneity biological membranes, bioinspired biomimetic (BBMs) aim emulate practical This Review highlights BBMs overcome limitations utilizing "division labor" between well-defined permeable pores impermeable matrix molecules seen membranes. We explore exceptional performance organisms, focusing on two major components: proteins (biological channels) lipid molecules. then discuss how these natural materials can be replaced with artificial mimics enhanced properties macro-scale are developed. highlight key demonstrations field that draw upon factors responsible transport through Additionally, current state-of-the-art methods fabrication reviewed challenges prospects future Finally, we provide considerations research could enable progress toward scale-up applicability.

Normal solutions of the Enskog–Vlasov–Landau kinetic equation were obtained within model positively and negatively charged solid spheres for system ion solution – porous medium. The Chapman–Enskog method was applied. Analytical expressions coefficients viscosity, thermal conductivity, diffusion ions in ionic medium derived by constructing equations hydrodynamics on basis normal equation.
