Advances and Challenges in Immune-Modulatory Biomaterials for Wound Healing Applications.

Wound healing progresses through three distinct stages: inflammation, proliferation, and remodeling. Immune regulation is a central component throughout, crucial for orchestrating inflammatory responses, facilitating tissue repair, and restraining scar tissue formation. Elements such as mitochondria, reactive oxygen species (ROS), macrophages, autophagy, ferroptosis, and cytokines collaboratively shape immune regulation in this healing process. Skin wound dressings, recognized for their ability to augment biomaterials' immunomodulatory characteristics via antimicrobial, antioxidative, pro- or anti-inflammatory, and tissue-regenerative capacities, have garnered heightened attention. Notwithstanding, a lack of comprehensive research addressing how these dressings attain immunomodulatory properties and the mechanisms thereof persists. Hence, this paper pioneers a systematic review of biomaterials, emphasizing immune regulation and their underlying immunological mechanisms. It begins by highlighting the importance of immune regulation in wound healing and the peculiarities and obstacles faced in skin injury recovery. This segment explores the impact of wound metabolism, infections, systemic illnesses, and local immobilization on the immune response during healing. Subsequently, the review examines a spectrum of biomaterials utilized in skin wound therapy, including hydrogels, aerogels, electrospun nanofiber membranes, collagen scaffolds, microneedles, sponges, and 3D-printed constructs. It elaborates on the immunomodulatory approaches employed by these materials, focusing on mitochondrial and ROS modulation, autophagic processes, ferroptosis, macrophage modulation, and the influence of cytokines on wound healing. Acknowledging the challenge of antibiotic resistance, the paper also summarizes promising plant-based alternatives for biomaterial integration, including curcumin. In its concluding sections, the review charts recent advancements and prospects in biomaterials that accelerate skin wound healing via immune modulation. This includes exploring mitochondrial transplantation materials, biomaterial morphology optimization, metal ion incorporation, electrostimulation-enabled immune response control, and the benefits of composite materials in immune-regulatory wound dressings. The ultimate objective is to establish a theoretical foundation and guide future investigations in the realm of skin wound healing and related materials science disciplines.

Engineered Regenerative Isolated Peripheral Nerve Interface for Targeted Reinnervation.

A regenerative peripheral nerve interface (RPNI) offers a therapeutic solution for nerve injury through reconstruction of the target muscle. However, implanting a transected peripheral nerve into an autologous skeletal muscle graft in RPNI causes donor-site morbidity, highlighting the need for tissue-engineered skeletal muscle constructs. Here, an engineered regenerative isolated peripheral nerve interface (eRIPEN) is developed using 3D skeletal cell printing combined with direct electrospinning to create a nanofiber membrane envelop for host nerve implantation. In this in vivo study, after over 8 months of RPNI surgery, the eRIPEN exhibits a minimum Feret diameter of 15-20µm with a cross-sectional area of 100-500 µm2, representing the largest distribution of myofibers. Furthermore, neuromuscular junction formation and muscle contraction with a force of ≈28 N are observed. Notably, the decreased hypersensitivity to mechanical/thermal stimuli and an improved tibial functional index from -77 to -56 are found in the eRIPEN group. The present novel concept of eRIPEN paves the way for the utilization and application of tissue-engineered constructs in RPNI, ultimately realizing neuroprosthesis control through synaptic connections.

Development of sinomenine hydrochloride loaded shell/core nanofibrous with pH‐responsive for colon‐targeted drug delivery

AbstractA series of colon‐targeted, sustained‐release, sinomenine hydrochloride (SH) loaded shell/core electrospun nanofibers are reported. The fibers have shells made of Eudragit S100 (ES‐100), and drug‐loaded cores comprising of Eudragit RS100 (ERS‐100) and SH. The essential characteristics of membranes are evaluated by scanning electron microscopy, transmission electron microscope, Fourier transformed infrared spectroscopy, and x‐ray diffraction. In vitro release of SH show that the shell/core nanofiber membranes can block drug release in the HCl buffer (pH 1.2), and the release time of the hydrophilic drug SH exceed 240 min at pH 7.4 phosphate buffer solution. In vitro drug release kinetics consistent with the first‐order model. The shell/core nanofiber can achieve colon‐targeted and sustained‐release properties, which can better prevent the loss of SH and relieve the adverse effects on gastrointestinal tract. In addition, the hemolysis and cytotoxicity tests manifest that the nanofiber membrane display good hemocompatibility and cytocompatibility. These results suggest the SH‐containing nanofiber membranes have potential applications as a colon‐targeted drug delivery system that sustained release. They also offer a theoretical foundation for the development of novel dosage forms for SH.

An electrospun iron oxychloride/polyacrylonitrile nanofibrous membrane with superhydrophilic and excellent regeneration properties: Achieving superior oil-in-water emulsion separation

Superhydrophilic polymer membranes are widely used in oil-water separation due to their excellent wettability, high efficiency, low cost, and good biocompatibility. However, challenges such as fouling adhesion and inadequate stability persist during the treatment of oily wastewater. Herein, a novel iron oxychloride/polyacrylonitrile (FeOCl/PAN) nanofibrous membrane with superhydrophilicity and remarkable regenerability was successfully fabricated through simple electrospinning technique, which maintained good physicochemical stability under various harsh conditions with the uniform distribution of FeOCl on PAN fibers. The surface morphology and chemical compositions of the optimized FeOCl/PAN membrane were studied by several characterization techniques. The introduced FeOCl nanocrystals through electrospinning endowed the membrane with a rougher surface structure, significantly improving the hydrophilicity of the FeOCl/PAN nanofibrous membrane. In the cross-flow isooctane-in-water emulsion separation experiment, the initial water flux recovery rate (FRR) of the membrane increased from 92 % for the pure PAN membrane to around 99 %. Meanwhile, the optimized FeOCl/PAN nanofibrous membrane achieved an emulsion (isooctane) flux of approximately 632.9 L m−2 h−1, with an oil droplet removal rate surpassing 99.4 %. Furthermore, by cleaning the membrane with H2O2 (60 mM, pH = 3), the FeOCl/PAN membrane exhibited an exceptionally high water flux recovery rate (∼100 %) after high-concentration paraffin-in-water emulsion (4000 mg L−1) separation. In addition, the FeOCl/PAN membrane also demonstrated excellent antifouling performance in bovine serum albumin (BSA) pollution experiment. In summary, this work might provide a unique strategy for preparing advanced functional membranes with superior efficiency and durability for emulsified oily wastewater treatment.

The mechanism of low molecular weight fucoidan-incorporated nanofiber scaffolds inhibiting oral leukoplakia via SR-A/Wnt signal axis.

Oral leukoplakia (OLK) is the most common oral precancerous lesion, and 3%-17% of OLK patients progress to oral squamous cell carcinoma. OLK is susceptible to recurrence and has no effective treatment. However, conventional drugs have significant side effects and limitations. Therefore, it is important to identify drugs that target OLK. In this study, scavenger receptor A (SR-A) was found to be abnormally highly expressed in the oral mucosal epithelial cells of OLK patients, whereas molecular biology studies revealed that low molecular weight fucoidan (LMWF) promoted apoptosis of dysplastic oral keratinocytes (DOK) and inhibited the growth and migration of DOK, and the inhibitory effect of LMWF on OLK was achieved by regulating the SR-A/Wnt signaling axis and related genes. Based on the above results and the special situation of the oral environment, we constructed LMWF/poly(caprolactone-co-lactide) nanofiber membranes with different structures for the in-situ treatment of OLK using electrospinning technology. The results showed that the nanofiber membranes with a shell-core structure had the best physicochemical properties, biocompatibility, and therapeutic effect, which optimized the LMWF drug delivery and ensured the effective concentration of the drug at the target point, thus achieving precise treatment of local lesions in the oral cavity. This has potential application value in inhibiting the development of OLK.

Deep trapped bipolar heterocharges enable electret nanofibrous membranes for high-efficiency PM0.3 filtration

Recently frequent global pandemic outbreak triggers the demand of high-efficiency aerosol filtration materials. Most of traditional electret air filters can hardly achieve high efficiency (>99.99 %) due to limited charge density and inappropriate charge distribution. The influence mechanism of nanofibers bipolar heterocharge configuration on electrostatic capture of airborne particles is still confusing. Herein, a novel strategy to create high-efficiency air filters based on electret nanofibrous membranes with deep trapped heterocharge is reported. Space charges and dipole charges with opposite polarity are formed in electrospun membranes composed of different polymers under in-situ charge injection and electric poling during electrospinning. Nanoscale spatial surface potential mapping on individual nanofiber characterized by Kelvin probe force microscopy demonstrates bipolar heterocharge distribution. Numerical simulation shows that fiber heterocharge distribution endows the electret membrane with greater electrostatic field intensity gradient, resulting in stronger electrostatic force between nanofibers and airborne particles. With bipolar heterocharge configuration and bimodal fiber diameter distribution, the nanofibrous membranes exhibit high-efficiency low-resistance filtration property against 0.3 μm NaCl particles (99.994 %, 97.4 Pa) at 5.3 cm s−1. Furthermore, benefiting from charges with deep trap energy of 1.12 eV, the membranes still maintain 99.972 % filtration efficiency after 40 h exposure in 95 % relatively humidity. The prepared membranes brings new insight in the design of high-efficiency and long-term stability air filtration materials for public health precaution. This study not only reveals influence mechanism of nanofibers heterocharge distribution on electrostatic attraction, but also provides useful guidance for fiber charge configuration design to improve aerosol filtration performance of electret filters.

Polyaniline/ZnO heterostructure-based ammonia sensor self-powered by electrospinning of PTFE-PVDF/MXene piezo-tribo hybrid nanogenerator

Self-powered sensors are receiving increasing attention for their environmental friendliness and energy efficiency. In this work, self-powered polyaniline/zinc oxide (PANI/ZnO) heterostructure-based ammonia (NH3) sensor was driven by polytetrafluoroethylene (PTFE)-polyvinylidene fluoride/Ti3C2Tx (PVDF/MXene) piezo-tribo hybrid nanogenerator (PTNG) at room temperature. PVDF/MXene nanofiber membranes were prepared using electrospinning technology to construct a PTFE-PVDF/MXene PTNG. This enhances the effective contact area and dielectric properties of the composite film, thereby increasing the surface charge density. Additionally, the synergy between the triboelectric and piezoelectric effects significantly improves the output performance of the PTNG, effectively enabling energy harvesting for wearable devices. In addition, ZnO/PANI composite materials with a large specific surface area and high active sites were prepared, and a self-powered ammonia sensor was constructed based on the impedance matching effect. Furthermore, by constructing a PANI/ZnO p-n heterojunction, the number of active sites has been increased, significantly enhancing the sensing performance. The sensor has a minimum detection limit of 0.1 ppm, and at an NH3 concentration of 10 ppm, the response rate reaches 96.1 %. This study provides insights for the development of self-powered gas detection systems and holds significant research and practical value in enhancing the performance of NH3 sensors.

Antibiotic delivery in the presence of green AgNPs using multifunctional bilayer carrageenan nanofiber/sodium alginate nanohydrogel for rapid control of wound infections

This study constructed bilayer nano-hydrogels using solvent casting and electrospinning techniques. The first layer consisted of a hydrogel containing sodium alginate and gellan gum, while the second layer was a carrageenan/polyvinyl alcohol nanofibrous membrane. The nanohydrogels were prepared with different doses of doxycycline antibiotic (0.12, 0.06, 0.03 g) and a fixed amount of silver nanoparticles (0.012 g), which were synthesized using the green method including Capparis spinosa leaf extract. The films were tested for their mechanical properties, swelling behavior, XRD, and FTIR, and their morphology was characterized using SEM. The biological properties of the nanohydrogels were also extensively assayed. X-ray diffraction analysis showed peak 111 for silver nanoparticles. Incorporating silver nanoparticles significantly enhanced nanohydrogels' mechanical and antibacterial properties and improved their ability to heal wounds. Nanohydrogels exhibited biodegradability, biocompatibility, anti-inflammatory properties (57.63 %), and high cell viability (>85 %) in laboratory conditions. The study confirmed that wound dressings containing doxycycline with controlled release are highly effective against pathogenic bacteria and prevent the formation of biofilms (92 %). The rats in-vivo study demonstrated that 100 % wound closure was achieved in nanohydrogels containing SA/GG/PVA/CAR/AgNPs/DOX0.12 after 14 days. The films could potentially lead to the development of new treatments against bacterial infections and inflammatory conditions of wounds.

Highly Stable Polyimide Composite Nanofiber Membranes with Spectrally Selective for Passive Daytime Radiative Cooling.

Passive radiative cooling technology without electric consumption is an emerging sustainability technology that plays a key role in advancing sustainable development. However, most radiative cooling materials are vulnerable to outdoor contamination and thermal/UV exposure, which leads to decreased performance. Herein, we report a hierarchically structured polyimide/zinc oxide (PINF/ZnO) composite membrane that integrates sunlight reflectance of 91.4% in the main thermal effect of the solar spectrum (0.78-1.1 μm), the mid-infrared emissivity of 90.0% (8-13 μm), UV shielding performance, thermal resistance, and ideal hydrophobicity. The comprehensive performance enables the composite membrane to yield a temperature drop of ∼9.3 °C, compared to the air temperature, under the peak solar irradiance of ∼800 W m-2. In addition, the temperature drop of as-obtained composite membranes after heating at 200 °C for 6 h in a nitrogen/air atmosphere can be well maintained at ∼9.0 °C, demonstrating their ideal radiative cooling effect in a high-temperature environment. Additionally, the PINF/ZnO composite membrane shows excellent chemical durability after exposure to the outdoor environment. This work provides a new strategy to integrate chemical durability and thermal resistance with radiative cooling, presenting great potential for passive radiative cooling materials toward practical applications in harsh environments.

Electrospunned nanofiber membranes of PTH-related peptide loaded biopolymers for osteoporotic bone defect repair

Despite the rapid development of the application of tissue engineering techniques in regenerative bone repair, the repair of severe pathologic bone defects, represented by osteoporotic bone defects, is still a huge challenge. Recent studies have identified local delivery of parathyroid hormone relative peptides (PTHrPs) as a novel pathway for bone repair as well, but how to load and locally release PTHrPs for good bone repair is a major obstacle. Here, a biopolymer of PLGA-PLL loaded with PTHrP1 is electrospunned into nanofiber membranes for guided bone regeneration. In vitro experiments show that PLGA-PLL synergized with PTHrP1 significantly promote osteogenic differentiation and angiogenesis, providing a favorable bone regeneration microenvironment. In vivo experiments show that the membrane recruits endogenous stem cells and promotes their ectopic osteogenic differentiation in an osteoporotic environment. Furthermore, the membrane can promote osteogenic differentiation and angiogenesis in situ and improve the local osteoporotic microenvironment, ultimately promoting the repair of bone defects. Therefore, present study provides a promising strategy for local delivery of PTH, which opens a new pathway for the treatment of osteoporotic bone defects.

Water-efficient evaporative cooling by sunlight-reflective radiative-cooling nanofibers

Evaporative cooling, which has the highest potential for energy transfer, is not sustainable without sufficient water. Here we present the membrane that can be used to protect the moisture from unnecessary evaporation. The membrane is composed of nanofiber non-woven fabric that is breathable and has high solar reflectance and high infrared emissivity for water-efficient evaporative cooling applications. The membrane prevents moisture from evaporating unnecessarily by blocking solar absorption and efficient thermal emission. Specifically, the membrane is composed of ∼400 nm diameter polyurethane fiber, which has a high MIE scattering effect on solar radiation (∼2500 nm wavelength), resulting in over 95% solar reflectance as well as over 95% of total infrared (IR) emissivity and IR transmittance at 50 g/m2 of membrane. In addition, it has sufficient breathability of over 16 mg•cm2•hr that the maximum evaporative cooling is about 100 W/m2. Twice the cooling time and 3 °C cooler surface by tandem of radiative cooling were confirmed in outdoor test of wet fabric covered with nanofiber membrane compared to wet fabric without membrane. This scalable and flexible membrane is applicable where the thermal cooling without energy consumption is required for net-zero energy consumption.

Fabrication and characterization of Ecklonia cava phlorotannin‐loaded PVA/PVP blend electrospun nanofibers as a potential diabetic wound dressing biomaterial

AbstractDiabetic wound healing remains a challenging issue, necessitating advanced dressings with active therapeutic agents to reduce inflammation and promote healing. Ecklonia cava phlorotannin (ECP) possesses therapeutic potential for wound healing including anti‐microbial, antioxidant, and anti‐inflammatory properties. Our previous study demonstrates the therapeutic efficacy of ECP‐loaded nanofibers in an in vitro hyperglycemic wound model. The present paper focuses on the detailed characterization of the polyvinyl alcohol (PVA)/polyvinylpyrrolidone (PVP) blend nanofiber incorporated with ECP. The ideal ratio, PVA80:PVP20, is selected to incorporate with ECP via the blend electrospinning method. To confirm the successful loading of ECP (0.5% and 1%), physicochemical characterization is conducted using scanning electron microscopy, Fourier‐transform infrared spectroscopy, and thermal analysis. Functionality assays are performed to evaluate their applicability as dressing biomaterials. Physicochemical analyses confirm the successful loading of ECP into the nanofibers. Overall, the ECP‐loaded PVA/PVP nanofiber membranes exhibit favorable wound dressing criteria, which attributed to high water absorption capacity (200%–400%), sufficient water vapor transmission rate (1550–1650 g/m2/d), high loading efficiency and slow release. Bioactivity tests indicate that the ECP's effectiveness is unaffected by the electrospinning process. Importantly, these membranes exhibit biocompatibility and nontoxicity to human dermal fibroblasts, indicating their potential as good diabetic wound dressings.

Batch preparation and characterization of zein-based beaded nanofiber membranes for active food packaging

Active packaging can efficiently enhance the shelf life of food, realizing the encapsulation and effective release of antibacterial agents and antioxidants. Zein is a natural protein derived from corn, widely used in food packaging. In this work, zein-based nanofiber membranes (NFMs) with beaded structures for food packaging were fabricated in batch using a self-made free surface electrospinning. The characteristics of NFMs were investigated in terms of their morphologies, structures and properties. The results illustrated that the antioxidant activity of NFMs was significantly improved after adding licorice extracts. Moreover, after adding the eugenol to the zein/licorice extract NFMs, zein/licorice extract/eugenol (ZLE) NFM had outstanding antibacterial activities against Staphylococcus aureus and Escherichia coli, which effectively prolonged the shelf-life of the grapes when it was used to package grapes. It proved that ZLE NFM had great potential in food packaging applications.

ATO and Cs0·33WO3 loaded bilayer nanofiber membrane doped polymer dispersed liquid crystals for infrared shielding

Liquid crystals possess a wide range of applications in modulating infrared (IR) light and have drawn great interest especially in near-infrared shielding and passive radiative cooling. Here, a composite structure containing polymer dispersed liquid crystals (PDLC) with antimony doped tin oxide and cesium tungsten oxide loaded bilayer nanofiber membranes with IR shielding properties is proposed. The composite film and the blank liquid crystal cell are irradiated simultaneously under IR light, and the temperature detector shows that the average temperature drop of the PDLC composite film in the scattered state and the fully transparent state over the blank sample are 6.8 °C and 4.1 °C, respectively. More importantly, the dynamic IR shielding properties of the composite films are demonstrated by patterning the nanofiber films. In addition, this organic/inorganic hybrid PDLC system not only modulates IR light, but also exhibits excellent electro-optical properties, aging resistance, flexural stability (1000 cycles), and tensile resistance. The composite film combines ease of preparation with compatibility for industrial-scale roll-to-roll or continuous manufacturing processes, highlighting the great potential of PDLC for applications in tunable optical heat transport materials.

Tailoring asymmetric wettability of Janus nanofiber membranes for directional oil transport and oil capture from oil/water mixtures and oil-in-water emulsions

The separation of oil from oil-in-water emulsions is crucial for the recycling of valuable resources. Janus membranes, characterized by their asymmetric configuration, have shown promise in capturing oil from these emulsions due to their ability to efficiently catch micro-size oil droplets with competitive flux rates, minimal energy costs, and fouling-free operations. This study explored the impact of asymmetric wettability on the oil capture capabilities of Janus nanofiber membranes (JNMs). The wettability of the JNMs’ skin layer was modified from oleophilic, with an oil contact angle (OCA) of ∼0°, to oleophobic, with an OCA of ∼142.7°. This adjustment significantly influenced the oil capture process. The oleophobic skin layer acted as a barrier, reducing oil permeation flux from the feed side. However, this same repellent effect facilitated the directional transport of oil once it breached the skin layer. Interestingly, this led to divergent outcomes in the JNMs’ ability to capture oil from oil/water mixture versus oil-in-water emulsion, a distinction not reported in previous studies. These findings are expected to contribute to the enhancement of Janus membranes, optimizing them for more efficient oil recovery from both oil/water mixture and oil-in-water emulsion.

Effect of layered double hydroxide-graphene oxide modifier composition on characteristics of polyvinylidene fluoride based nanocomposite membranes in the separation of Cu2+

This research explored the modified polyvinylidene fluoride (PVDF) nanofiber membranes with a composite of layered double hydroxide (LDH) and graphene oxide (GO) to enhance biofouling resistance. The PVDF/LDH-GO nanocomposite membranes were synthesized via vacuum filtration. FTIR analysis confirmed nanocomposite formation with new peaks indicating the presence of GO and LDH. Variations in the LDH:GO ratio affected the physical, mechanical, and performance properties of the membranes. Based on SEM imaging, the 1:1 LDH: GO ratio exhibited the highest Young's modulus and smallest pore sizes. LDH-GO incorporation increased the mechanical strength, porosity, roughness, hydrophilicity, and pure water permeability of the PVDF membranes. The combination of these factors led to balanced permeability and selectivity values towards Cu2+ solution feeds. LDH-GO was proven effective in modifying the PVDF membrane surface for water treatment and inhibiting biofouling up to 64% against E. coli.

Facile dual-functionalization of PEN nanofibrous membranes with solar evaporation and photocatalysis for efficient dye wastewater purification

Purification of dye wastewater by combining photocatalytic degradation with solar energy-driven interfacial water evaporation has emerged as a promising approach to address water pollution in recent years. In this work, a high-performance polymer, polyarylene ether nitrile (PEN), was electrostatically spun to construct a robust nanofibrous substrate, then dual-functionalized using polyaniline (PANI) and titanium dioxide (TiO2) via a facile polydopamine (PDA)-assisted vacuum self-assembly method. Moreover, the CA of the PEN membrane after PDA and PANI@TiO2 treatment changes from 20° to 0° within 0.4 s, showing superhydrophilic properties and providing rapid water supply for water evaporation. PANI and TiO2 were employed as the photo-thermal conversion component and photocatalytic component, respectively. The fabricated dual-functionalized PANI@TiO2/PEN composite nanofibrous membrane exhibited a high water evaporation rate of up to 3.23 kg m−2 h−1 under a simulated solar illumination of 1 KW m−2. Owing to the reduction in the photoelectron-hole recombination rate promoted by PANI, the composite nanofibrous membrane demonstrated a favorable dye removal rate of 92.18% in 6 h for methylene blue (MB). Furthermore, the robust PEN nanofibrous skeleton conferred the composite membrane with thermal resistance and corrosion resistance properties, ensuring long-term performance in harsh environments. The facile fabricated PANI@TiO2/PEN membrane achieved comprehensive performance, offering a promising strategy by combining solar-driven interfacial water evaporation and photocatalytic degradation for water purification.

Boronate-modified electro-spun Fe doped carbon nanofibrous membrane for selective dye adsorption, catalytic degradation, and bacterial inhibition in treatment of water

Recently, dye and microorganism have become the main sources of water pollution due to the rapid development of modern industries and wantonly draining of living sewage. Therefore, the efficient removal of dye and microorganism from the wastewater have attracted considerable attentions of the scientists and engineers around the world. In this regard, a novel phenyl boronic acid (PBA) modified electro-spun Fe doped carbon nanofibrous membrane, C/Fe@PBA, was fabricated in this study for simultaneously selective removal of dye and efficient inhibition of bacteria in water. Firstly, the C/Fe@PBA displayed selective adsorption towards Congo Red (CR) among other dyes by the adsorption order of CR>Methyl Orange (MO) > Neutral Red (NR) > Methylene Blue (MB) > Malachite Green (MG) > Rhodamine B (RhB) with adsorption ability at 25.75, 8.41, 7.11, 7.02, 5.41, and 3.13 mg·g−1. The pseudo first order kinetics and Langmuir isotherm model is calculated to better match the adsorption process of the as prepared membrane towards CR. After 7 rounds of adsorption desorption or 5 degradation cycles, the carbon membrane showed a removal efficiency of 62.2 % or 57.4 %, respectively. Furthermore, the C/Fe@PBA can be employed as effective catalyst to degrade CR in presence of H2O2 under 808 nm near-infrared (NIR) irradiation by the photothermal effect, and the possible catalytic mechanisms and degradation pathway were proposed. Moreover, the as prepared membrane exhibited high bactericidal rate of 99.94 % and 97.44 % against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), respectively. In conclusion, the as prepared carbon membrane with ability of selective adsorption, catalytic degradation, and bacterial inhiation is a promising candidate of filtration membrane in practical sewage management.
