Abstract Permeability and selectivity are two important parameters for evaluating membrane separation performance. In this work, the polysaccharide-functionalized gold nanoparticles (DexDTM-AuNP) are synthesized by one-step reduction with NaBH 4 and used as additive for modification of PES membrane to improve the hydrophilicity of the membrane. In comparison with the pristine PES membrane, the water contact angle (WCA) of the DexDTM-AuNP-modified membrane significantly decreases. When the content of DexDTM-AuNP is 3 wt%, the WCA of the modified membrane decreases from 89.3° to 61.1°, indicating excellent hydrophilicity. The modified membrane shows high pure water flux of up to 134.5 L m −2 h −1 , and the rejection ratio for bovine serum albumin, congo red, and methyl blue are 98.8, 99.3, and 93.6%, respectively. DexDTM-AuNP-modified membrane exhibits excellent hydrophilicity, anti-fouling ability, and separation performance. Therefore, the strategy has great potential for practical applications in water purification and other separation fields. Graphic Abstract

Polyvinylidene fluoride (PVDF) has unique electrochemical oxidation resistance and is the only binder for high-voltage cathode materials in the battery industry for a long time. However, PVDF still has some drawbacks, such as environmental limitations on fluorine, strict requirements for environmental humidity, weak adhesion, and poor lithium ion conductivity. Herein, the long-standing issues associated with high-voltage lithium cobalt oxide (LiCoO 2 ; LCO) are successfully addressed by incorporating phenolphthalein polyetherketone (PEK-C) and phenolphthalein polyethersulfone (PES-C) as binder materials. These binders have unexpected electrochemical oxidation resistance and robustness adhesion, ensure uniform coverage on the surface of LCO, and establish an effective and fast ion-conductive CEI/binder composite layer. By leveraging these favorable characteristics, electrodes based on polyarylether binders demonstrate significantly better cycling and rate performance than their counterparts using traditional PVDF binders. The fast ion-conductive CEI/binder composite layer effectively mitigates adverse reactions at the cathode–electrolyte interface. As anticipated, batteries utilizing phenolphthalein polyarylether binders exhibit capacity retention rates of 88.92% and 80.4% after 200 and 500 cycles at 4.5 and 4.6 V, respectively. The application of binders, such as polyarylether binders, offers a straightforward and inspiring approach for designing high-energy-density battery materials.

Nature is the source of human being's creativity and always inspires people to break through the existing bottleneck of science and technology. Electric eel (Electrophorus electricus) relying on ion channel in electrocyte can convert salinity gradient energy to electricity power with potentials of ~600 V to stun prey and ward off predators. Inspired by biological ion channels, artificial nanochannels have been extensively explored to mimic the control of ion flow in nanosize confinement space and apply in salinity gradient power generation. In this paper, polyether sulfone/sulfonated polyether sulfone (PES/SPES) membranes with large amount of nanochannels are constructed by using phase separation method to be applied in the salinity gradient power generation field. The content of SPES, the concentration of casting solution , and the thickness of prefabricated membrane were taken into account to control the structural and surface charge distribution of membrane. The prepared serials PES/SPES membrane with nanopore structure display much proper cation selectivity, excellent ion conductivity and output power density (reach up to 2.48 W/m 2 ) for salinity gradient power generation. In addition, the proposed membrane with low cost and easy casting process shows great potential for the practical application in salinity gradient power generation.

Sulfonated polysulfone (SPSF) with different sulfonation degrees (10%, 30%, and 50%) was added to polyethersulfone (PES) to improve the separation and antifouling performance of polyethersulfone ultrafiltration membranes. The PES/SPSF blend ultrafiltration membrane was prepared by the non-solvent induced phase inversion method (NIPS), and the effect of sulfonation degree on the ultrafiltration performance was studied. The compatibility of SPSF and PES was calculated by the group contribution method, and confirmed by differential scanning calorimetry (DSC). The morphology and surface roughness of the membrane were characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM), the chemical composition of the membrane was analyzed by X-ray photoelectron spectroscopy (XPS) and infrared spectroscopy (FTIR), and the permeability and anti-fouling performance of the blend membrane were studied through filtration experiments. The research shows that the flux and anti-fouling performance of the blend membrane have been improved after adding SPSF. When the sulfonation degree of the SPSF is 30%, the pure water flux of the blend membrane can reach 530 L m−2 h−1, the rejection rate of humic acid (HA) is 93%, the flux recovery rate of HA increases from 69.23% to 79.17%, and the flux recovery rate of BSA increases from 72.56% to 83%.

Different nonsolvent additives, namely, diethylene glycol, n -butyl alcohol (NBA), and ethylene glycol monomethyl ether, were added into the casting solution (polyethersulfone/dimethylformamide/lithium chloride) to prepare ultrafiltration (UF) membrane via phase inversion. The effects of different additives and their concentration on the pore structure of the prepared UF membrane were studied. The cross-sectional morphology of the membrane was observed via scanning electron microscopy. The addition of nonsolvent additives improved the large-cavity structure of the membrane. When the additive was low-content NBA (1–3 wt %), the membrane pore structure transformed from large-cavity structure to fully sponge-like structure. When the content of additive NBA was 3 wt %, the flux of the prepared UF membrane was 130.45 L (m −2 h −1 ), the rejection of PEG20000 was 95.54% and the flux remained high at 4 bar in long-term stability test. © 2019 Wiley Periodicals, Inc.

Quorum sensing inhibitors (QSIs) can inhibit biofilm formation by regulating the synthesis of extracellular polymeric substances (EPS), thus alleviating biofouling in the membrane filtration process. In this study, utilizing the adhesion ability of a mussel-inspired biomimetic material, polydopamine (PDA), natural quorum sensing inhibitors, vanillin and furanone, were modified on a commercial polyethersulfone (PES) ultrafiltration (UF) membrane to inhibit the formation of biofilm fouling. We proved that QSIs were successfully grafted onto the membrane surface without blocking the pore structure, and the pure water flux of the membrane was simultaneously improved due to hydrophilicity improvement. The vanillin-modified membrane significantly inhibited the biofilm formation of P. aeruginosa PAO1 (81.7% inhibition rate), while furanone had a certain inhibitory effect on E. coli MG1655 and PAO1. We also tested the modified membrane in the dynamic filtration of simulated wastewater, in which both modified membranes alleviated biofouling.

Fabrication of membranes with high antifouling and self-cleaning ability is a long-term pursuit of research community. For this purpose, the current work proposed a strategy to use an external magnetic field to arrange the magnetic TiO 2 @Ni particles (MNPs) onto the polymeric polyether sulfone (PES) membrane surface. The characterization results clearly indicated that the MNPs were successfully embedded onto the membrane surface instead of uniformly distributing into the membrane bulk. Because of this superficial distribution, the prepared composite membrane exhibited a flux of 871.2 ± 2.9 L·m −2 ·h −1 ·bar −1 , which was 5 times flux of the pristine PES membrane. Meanwhile, it remained a rejection of 95.85% bovine serum albumin (BSA), which was also better than that of the pristine PES membrane. The cycle filtration experiments verified that the composite membrane possessed promoted antifouling ability for filtrating BSA, yeast extract fermentation (YEF), ammonium alginate (SA) and humic acid (HA) solutions. The antifouling mechanism was analyzed by the total interaction energies (ΔG Total ), which were quantitatively evaluated by using the extended Derjaguin–Landau–Verwey–Overbeek (XDLVO) theory. Moreover, it was interestingly found that the composite membrane possessed a self-cleaning property under radiation of UV light and sunlight. The optimal membrane after self-cleaning presented flux recovery ratio (FRR) of 75.4%, 99.56%, 92.11% and 98.26% for BSA, YEF, SA and HA solutions, respectively. This work demonstrated a novel way to fabricate membranes with high antifouling and self-cleaning ability for water treatment.

To overcome challenges associated with the “trade-off” effect and membrane fouling, the high-performance ultrafiltration membranes were prepared by blended multi-branched nanocellulose (Multi CNC) into polyethersulfone (PES) matrix using non-solvent induced phase separation (NIPS) technology. The as-prepared composite ultrafiltration membranes have high hydrophilicity, thicker skin layer and lower negative charge due to the abundant polar groups of carboxyl ( COOH) in Multi CNC. As the results, the water flux and Bovine serum albumin (BSA) rejection of the composite membranes with 1 wt% Multi CNC reached to 961.65 L/m 2 ·h and 96.4 %, while the flux and rejection of the original PES membrane was only 702.04 L/m 2 ·h and 86.2 % respectively, thus the “trade-off” was effectively improved by loading of Multi CNC. Moreover, the flux recovery ratio (FRR) of MCP1 (FRR = 74.08 %) was 2.1 times as much as the original PES membranes (FRR = 34.81 %) in the water-BSA-water filtration process, verified that the introduction of Multi CNC could effectively improve the anti-fouling ability of composite membranes. Such hydrophilic composite ultrafiltration membranes with robust mechanical performance could be developed for pharmaceutical and biotechnological industries.

This paper introduces different contents (0–20 mol%) of the third monomer 1,4-cyclohexanedimethanol (CHDM) into the coupling reaction system of ethylene carbonate (EC) and dimethyl succinate (DMSu) to synthesize polyethylene succinate (PES) copolyester (PESG), aiming to disrupt the regularity of the PES molecular chain structure, reduce its crystallization ability, and improve its brittleness. The novelty lies in the use of this novel reaction system that not only enhances the toughness of the copolyester by disrupting its crystallinity, but also allows for the green co-production of DMC while maintaining biodegradability. The results of Fourier transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance ( 1 H-NMR), and gel permeation chromatography (GPC) tests indicate that the molecular backbone of the PESG sample contains two types of repeating structural units, and the molecular weight meets the expected standard. Differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and X-ray diffraction (XRD) showed that the thermal decomposition temperature of PESG was above 380°C, and the melting temperature decreased, and the crystallization ability weakened. Mechanical and degradation tests showed that the toughness of PESG was improved and had good degradation performance. The modified copolyester shows significant potential for applications in packaging materials and biodegradable films, making it a promising material for sustainable applications.

In this study, different nanoporous polyethersulfone (PES) fiber mats were fabricated for bilirubin adsorption via electrospinning technique with different solvent compositions of tetrahydrofuran (THF) and N,N-dimethylformamide (DMF). The porous structure of the PES fiber mats was investigated via scanning electron microscope (SEM) and Brunauer-Emmett-Teller (BET) measurements. The results showed that the PES fiber mats electrospun prepared with THF/DMF (1/3) exhibited the largest surface area of 45.988 m 2 /g and pore volume of 0.3612 cm 3 /g, respectively, as well as the fastest adsorption rate and the largest adsorption capacity (175.98 mg/g) for bilirubin than others. In addition, the pseudo-first order kinetic model was applied to analyze the adsorption process .

To address the growing threat of mercury ion pollution in water, a biomimetic nanocomposite membrane was developed by modifying UiO-66-NH₂ with the thiol ligand DPEN, inspired by the Hg(II)-binding mechanism of cysteine in proteins. The membrane was fabricated through in-situ synthesis of UiO-66-NH₂ on a porous polyethersulfone support, followed by chemical grafting of DPEN. Comprehensive characterization via FT-IR, XPS, XRD, SEM confirmed the successful formation of the modified nanoparticles. The fabricated membrane demonstrated outstanding performance, achieving over 99 % removal of Hg(II) with a high pure water flux of 6344 L·m −2 ·h −1 . It also exhibited excellent recyclability, retaining 97.4 % removal efficiency after ten cycles, and maintained structural stability across a broad pH range (3–9). This biomimetic approach offers a promising strategy for designing efficient and durable membranes for heavy metal removal, with significant potential in environmental water treatment.

In this work, polyethersulfone (PES) membranes with superior antifouling and anticoagulant properties were prepared effectively and efficiently through the non-solvent induced phase separation (NIPS) method via in situ copolymerization mediated surface zwitterionicalization. Glycidyl methacrylate (GMA) was copolymerized with poly(ethylene glycol)methyl ether methacrylate (PEGMA) in the casting solution to form amphiphilic P(GMA-r-PEGMA), which not only enhanced the hydrophilic properties of PES membranes but also provided the active chemical sites for the immobilization of zwitterionic lysine on the membrane surface. Upon modification, the membranes exhibited suppressed protein adsorption, improved wettability, better antifouling and anticoagulant abilities (suppressed platelet adhesion, a prolonged plasma clotting time and improved hemolytic activity) compared to the virgin PES membrane. The water contact angle of the modified membranes was decreased to as low as 37° while the flux recovery ratio was increased to as high as 99.1%. This work provided an effective and efficient way for the fabrication of low fouling membranes without adding any additional steps to the process of membrane formation.
