Superior permeability and high selectivity are crucial performances criterion for reverse osmosis (RO) membranes. Inspired by aquaporin-based biomimetic membranes, the loose liposomes as artificial water channels were prepared by thin-layer hydration method with lyso -phospholipids (C14lyso) and cholesterol followed by incorporating liposomes into the polyamide selective layer via in situ interfacial polymerization to fabricate liposomes-based RO membranes (TFC-C14lyso). Stopped-flow tests verified that C14lyso liposomes possess fast water transportability and the effect of C14lyso liposomes on the intrinsic structure of the polyamide selective layer was comprehensively explored. Meanwhile, the structure and performance of the TFC-C14lyso membranes could be regulated by varying the liposome concentrations. As a result, TFC-C14lyso-2 (the concentration of C14lyso liposomes is 0.25 mg/mL) presented an optimal separation performance, showing high water permeance of 3.80 L m −2 h −1 bar −1 and NaCl rejection of 98.6 %. Moreover, the separation mechanism regarding the enhanced permeability of TFC-C14lyso-2 was profoundly revealed via the structure and performance comparison with TFC-DOPC fabricated by incorporating dense DOPC liposomes into its PA selective layer. Building on these studies, our work may provide a facile and versatile pathway for designing advanced membranes in desalination.

Passive daytime radiative cooling is receiving more and more attention as a cooling method that does not consume energy to cool objects. However, most radiative cooling materials require the mixing of multiple particles, which increases the manufacturing process requirements. Most radiative cooling materials are susceptible to outdoor abrasion, pollution, and UV exposure, which leads to decreased performance. In this paper, the biomimetic film with both radiative cooling and self-cleaning functions was prepared by a simple evaporation-induced self-assembly process and spraying process using Al2O3 as the main radiatively cooling raw material, poly(vinylidene fluoride-co-hexafluoropropylene) [P(VDF-HFP)] as the additive, and polydimethylsiloxane as the binder. Therefore, we can get a biomimetic-Al2O3–P(VDF-HFP)-PDMS film (BAPPF). The BAPPF was spectrally selective. Specifically, the reflectance of BAPPF in the solar spectrum (0.45–0.89 μm) exceeded 100%, and the average reflectance in the main thermal effect of the solar spectrum (0.78–1.10 μm) was 99.92%. In addition, the BAPPF had 96.97% reflectance in the solar spectrum (0.3–2.5 μm) and 90.55% mid-infrared emissivity in the atmospheric window (8–13 μm). The combined performance enabled BAPPF to reduce temperature by up to 8.4 °C over air temperature in outdoor tests. What’s more, BAPPF had excellent superhydrophobic properties, with a water contact angle of up to 159°. The self-cleaning of the BAPPF prevented contamination and maintained cooling even when working outdoors for long periods of time. Furthermore, the BAPPF maintained high performance after mechanical friction, chemical corrosion, UV aging, and water impact, which has broad reference value and application prospects.

Designing and constructing a stable water-retention layer acting as the isolation between the oil and membrane surface holds great significance for solving the membrane fouling problems in oil/water separation, including common layered oil/water mixtures, immiscible oil-in-water emulsions, and even high-viscosity crude oil-in-water emulsions. Inspired by the self-cleaning property of sea urchin thorns, a bioinspired anti-oil-fouling hierarchically structured membranes decorated with urchin-like α-FeOOH particles was successfully prepared via the layer-by-layer (LBL) self-assembly method, maintaining numerous effective micro-nanopores. The hierarchical structured membrane exhibited superior superhydrophilicity/underwater superoleophobicity, high water-retention ability, and preferable anti-oil-fouling properties. Furthermore, the biomimetic membrane with controllable pore sizes could not only separate common layered oil/water mixtures but also effectively separate immiscible surfactant-stabilized oil-in-water emulsions of both low-viscosity crude oil and high-viscosity crude oil with an ultrahigh water flux up to 2598.4 L m–2 h–1 and an outstanding separation efficiency of 98.5%, revealing its promising prospect in oily wastewater treatment.

Inspired by biological aquaporins, artificial water channels (AWCs) can achieve high-performance for thin-film composite (TFC) reverse osmosis (RO) membranes. In our work, two types of liposomes (C18lyso and D5A liposomes) with superior permeability serving as AWCs were designed by regulating the molecular structures of lipids, in which D5A liposomes have a better ability to water transport water molecules. Herein, liposome-based RO membranes (TFN-C18lyso and TFN-D5A) were fabricated via in situ interfacial polymerizations (IP). The resulting TFN-C18lyso shows an increase in water permeability of ∼ 51.4 % (up to 3.83 L m −2 h −1 bar −1 ) while TFN-D5A displays an increase in water permeability of ∼ 67.2 % (up to 4.23 L m −2 h −1 bar −1 ), and both membranes keep high rejection of ∼ 98.6 %. Moreover, both TFN-C18lyso and TFN-D5A present good separation stability, chemical resistance, and good desalination. Our work provides a valid and versatile foundation for developing advanced biomimetic membranes in water treatment.

Oil fouling is a major obstacle for the efficient and reliable oil-water separation of mesh-based membrane processes. Innovations in membrane materials and preparation processes are therefore needed to develop anti-oil-adhesion strategies. This study reports a series of vein-supported porous membranes (VPMs) fabricated by casting polyacrylonitrile (PAN) on veins through non-solvent induced phase separation, confirmed by FTIR, SEM and XRD characterizations, and applied as an effective oil-water separation membrane. Benefiting from the combination of tubular-like vein and hydrophilic PAN, the resultant VPM demonstrates a fine-tunable morphology and superhydrophilicity, extremely boosting underwater superoleophobicty, mechanical strength and superior performance for oil/water separation to various oily mixtures/emulsions, showing underwater oil contact angles over 157° and nearly zero underwater oil adhesion. In oil-water mixture separation process, a separation efficiency of > 99% and ultrahigh permeation flux of 9592 LMH can be achieved under gravity conditions using VPM-2 (casting with 2 wt% PAN). For oil-water emulsion separation, a highest flux of 3011 LMH and trace oil concentration <10 ppm in the filtrate was generated using VPM-9 (casting with 9 wt% PAN) under a low external pressure of 3 kPa. The VPM-2 membrane is further carried out a 40-h cycling separation, showing a constantly stable water flux of ~6000 LMH. The developed VPMs open a bright path to use biomaterials for design and fabrication of novel oil-water separation membrane.

The synthesis of high-performance materials for purifying oily wastewater, especially stable oil-in-water emulsions that aromatic pollutants present in water, is of growing scientific and technological significance. Novel hierarchical architectures of Ag clusters deposited biomimetic membrane have been synthesized by ingeniously selecting the mussel-inspired polydopamine coatings as an intermedium layer followed by a facile wet chemical reduction method. The target micro-scaled Ag clusters which are composed of innumerable nanoparticles, firmly load on the surface of sub-micrometer polydopamine spheres (PDSs) benefiting from the chelating capacity and benign reduction ability of PDSs. The resultant Ag@PDSs deposited membrane with enormous specific surface area exhibits superhydrophilicity and underwater superoleophobicity, making it highly promising for efficient separation of various surfactant-stabilized oil-in-water emulsions and synchronously excellent catalytic reduction of water-soluble aromatic dyes. Moreover, such a construction mode can effectively prevent the aggregation and possible leaching of Ag particles, which greatly contributes to the outstanding cyclic performance and good antibacterial activity. All these features demonstrate that the two-step strategy is a facile approach to design and exploit the deposited Ag@PDSs composites for diverse actual applications in oil/water emulsion separation, catalysis and antibacterial agent.

The efficient and rapid separation of oil from stabilized oil-in-water emulsions with micro/nanometer size is a global challenge. Owing to the low oil content in oil-in-water emulsions, separating the oil by simply controlling the surface wettability is difficult. Controlling the pore size of the membrane surface to achieve separation will lead to a sharp decrease in flux. Herein, inspired by cell membrane transportation, a hydrophilic/hydrophobic bifunctional Janus membrane for stable oil-in-water separation was prepared by simple surface polymerization and vapor diffusion. The prepared Janus membrane contained a hydrophobic side and hydrophilic polyamine layer. When used for oil-in-water emulsion separation, the polyamine layer accumulated micro/nanometer oil droplets, forming an oil layer on the hydrophobic surface. Water was retained by the 1 H ,1 H ,2 H ,2 H -perfluorooctyl trichlorosilane layer, allowing oil droplets to selectively permeate through the membrane, achieving the separation effect. As the pore size of the modified fabric was basically unchanged, the permeation flux was fast (1.53×10 3 Lm −2 h −1 ). Furthermore, the poly( N,N -dimethylaminoethyl methacrylate) layer destroyed the emulsion stability, making the emulsion droplets aggregate without affecting the separation efficiency with fast permeation flux. Therefore, the prepared bifunctional Janus membrane shows great potential for actual wastewater treatment.

A polysulfone (PSF)-based hollow fiber affinity membrane for in vitro endotoxin elimination was explored and prepared successfully. This depended on the well-known hemocompatibility of PSF membrane. The PSF hollow fiber membranes were firstly activated by a chloromethylation reaction, and treated with ethylenediamine and glutaraldehyde successively. L-Serine (Ser) was finally immobilized on the surface of the membranes as the functional ligand. The modified membrane was confirmed by X-ray photoelectron spectroscopy, attenuated total reflectance Fourier transform infrared spectroscopy, and contact angle analysis. L-Ser density up to 8.4 μmol cm−2 on PSF membranes could be achieved. The adsorption performance was preliminarily studied by comparing the PSF membrane and PSF–Ser membrane in deionized water and sodium phosphate buffer, showing that the PSF–Ser membrane had improved endotoxin adsorption capacity with decreased Bovine Serum Albumin (BSA) adsorption. The PSF–Ser membrane was further investigated in human plasma, and showed excellent removal efficiency and specificity for endotoxin. These results demonstrate the promising application potential of this novel affinity membrane in sepsis therapy.

Aquaporins play a promising role in the fabrication of high-performance biomimetic membranes. Interfacial polymerisation is a promising strategy for synthesizing aquaporin-based membranes. In this study, robust and high-performance aquaporin-based biomimetic membranes were successfully fabricated by interfacial polymerisation, and the membrane separation performance and interfacial polymerisation method were systematically evaluated. The effects of modification methods on the performance of aquaporins-based biomimetic membranes, including sodium hypochlorite and thermal post-treatment, protein-to-lipid ratio, liposome concentration and the addition arrangement of aquaporins were also investigated. Morphological observation suggested that the introduced proteoliposomes were completely embedded in the polyamide layer and that their spherical shape was preserved. Sodium hypochlorite post-treatment and thermal treatment were beneficial in improving the water flux and salt rejection of the resultant membrane without sacrificing the aquaporin activity. The biomimetic membranes had a high water flux and salt rejection, which were almost twice that of the control membranes, after aquaporin-based proteoliposomes were incorporated with an appropriated protein-to-lipid ratio and liposome concentration. The addition arrangement of aquaporins during the interfacial polymerisation procedure significantly influence the obtained membrane's structure. Lastly, this article introduces valuable and systematic research on interfacial polymerisation fabricated aquaporin-based biomimetic membranes with outstanding separation performance.

Oily wastewater poses a severe threat to the environment and human health, and its disposition is a worldwide urgency. Rencently, Janus membranes has provided excellent selectivity for oil/water separation due to thin layers of different wettability on opposite sides. However, the fabrication of Janus asymmetric multilayer with simple syntheses and excellent stability has been proved challenging. Herein, a Janus polydopamine-polytetrafluoroethylene/titanium dioxide (PDA-PTFE/TiO 2 ) membranes were inspired by dual-bionic strategy (lotus leaf and mussel) and constructed by centrifugal spinning technology. The membranes showed significant separation efficiency for both water–oil mixtures and emulsions above 99%. Most notably, the separation efficiency of the membranes are still maintained above 98.5% after 24 h immersion in the corrosive solutio. Meanwhile, the nanofiber membrane has outstanding reusability, acid/alkali resistance, and mechanical stability. Therefore, the dual-bioinspired Janus micro/nano PTFE/TiO 2 membrane suggests a promising potential application for a sustainable and effective oil–water separation membrane in the future.

Creating a facile and efficient porous membrane for the comprehensive treatment of both insoluble and soluble pollutants from water is of great significance, yet remains challenging. Here, we present a facile strategy to prepare charged nanofibrous membranes assembled from spider silk-like humped SiO2/polyamide 66 (PA66)/polyaniline (PANI) nanofibers by combing Plateau−Rayleigh instability-induced assembly and in situ synthesis. The obtained nanofibrous membranes possess micro/nanostructured surfaces with promising superhydrophilic and underwater superoleophobic property, which are attributed to the synergy of hierarchical roughness and hydrophilic matrix. Combined with the superwettability and the integrated property of submicron pore size, high porosity, and good pore interconnectivity, the membranes can separate various oil-in-water emulsions with a remarkable permeation flux of 5403 l m−2 h−1 and a high separation efficiency (total organic carbon content <5 mg l−1). Moreover, attributed to the Laplace pressure difference and positive potential of the spindle-knotted nanofibers, the biomimetic nanofibrous membranes could remove the filter cake during separation. In addition, the membrane exhibits a remarkable adsorption-reduction capacity of hexavalent chromium. The synthesis of such attractive nanomaterials may provide new insights into the development of multifunctional separation materials for environmental applications.

Achilles tendon injuries present significant clinical challenges due to limited regenerative capacity and frequent adhesion formation. Here, we report a melatonin-loaded Janus fibrous membrane (MLT@JFM) that mimics the native paratenon’s structure and function to promote scarless tendon healing. The biomimetic membrane consists of an inner methacrylated silk fibroin (SFMA) layer that promotes tendon stem cell functions and an outer melatonin-loaded polycaprolactone methacryloyl (PCLMA) layer that prevents adhesion formation. Through photo-cross-linking and structural interlocking, MLT@JFM achieves excellent mechanical properties and stable fixation around injured tendons. In vitro studies demonstrate that MLT@JFM effectively scavenges reactive oxygen species, modulates macrophage polarization, and maintains tendon stem cell phenotype under inflammatory conditions. In a rat Achilles tendon injury model, MLT@JFM significantly enhances functional recovery and biomechanical properties while preventing adhesion formation. Transcriptomic analysis reveals that MLT@JFM promotes scarless healing through synergistic regulation of oxidative-inflammatory cascades and the enhancement of tissue regeneration. This study presents MLT@JFM as a promising therapeutic strategy for tendon repair and provides new insights into biomaterial-mediated tissue regeneration.
