Separating of oil-water emulsions under harsh conditions is a major challenge for membrane-based filtration systems. In this study, a well-stabilized electrospinning nanofibrous membrane was successfully fabricated by combining a high-performance engineering polyarylene ether nitrile (PEN) with polydopamine (PDA), and silver nanoparticles (Ag NPs). The employed PEN has comprehensive performance in thermoresistant, anti-corrode and mechanical properties, which was expected to be a robust polymer matrix. Ag NPs were loaded on PEN electrospinning nanofibrous membranes via PDA coating and in situ growth. Morphological measurements revealed a hierarchical structure of fabricated Ag@PDA/PEN membrane with Ag NPs formed in situ covered on the surface. The particle size of Ag NPs was mainly in the range of 50–85 nm and the diameter of PEN fiber was located at∼0.39 μm. The water contact angle (CA) of membranes increased from 30 o to 130 o by the increasing Ag NPs formation. As a result, the prepared composite membranes reached 4978.71 L/m 2 h and 99 % for permeate flux and good retention rate for oil-water emulsion separation, respectively. Moreover, the high-performance PEN further endowed the tough stability and durability of the obtained composite membranes, which can tolerate corrosive emulsions, resist high temperatures, and maintain a high separation efficiency after cycle reuse. Furthermore, the as-prepared membranes demonstrated excellent anti-bacterial properties (>99.99 %) inherited from the introduction of Ag NPs. Therefore, the comprehensive anti-corrode, anti-heat, and anti-bacterial performance provide the fabricated robust Ag@PDA/PEN electrospinning nanofibrous membrane a broad prospect for purifying water resources, especially industrial wastewater treatment under harsh conditions.

In recent years, with the breakthroughs in nanomaterial technology and manufacturing processes, the energy density of energy storage devices has been significantly improved, laying the foundation for their large-scale commercial applications. Flexible dielectric energy storage materials have received extensive attention due to their advantages such as low processing difficulty, light weight, efficient charge–discharge processes, and excellent energy storage density. However, in polymer-based nanocomposites, there are problems such as poor dispersion of nanoscale fillers and the formation of physical defects, which in turn affect the mechanical properties. To address the above issues, in this study, through surface modification technology, insulating polydopamine (PDA) was coated on the surface of barium titanate (BaTiO 3 , BT) nanoparticles to synthesize functional BT core–shell particles, which were then doped into a polyarylether nitrile (PEN) matrix with good dielectric properties to prepare PEN/BT@PDA composite dielectric materials. The influence of surface-modified BT core–shell particles on the microstructure and energy storage performance of PEN-based composite dielectric materials was investigated. The results show that the BT@PDA particles are uniformly dispersed and have good compatibility within the PEN matrix. At the same time, the dielectric properties and breakdown performance of PEN/BT@PDA have also been improved. Under an electric field of 100 Hz, the maximum dielectric constant of the PEN/BT@PDA composite dielectric material is 6.8, which is a 74 % increase compared to the original PEN film, and the dielectric loss is 0.052, showing frequency dependence. The BT@PDA particles can capture the free electrons that are free in the PEN system under an electric field, reducing the carrier mobility, thus suppressing the formation of conductive paths inside the material, regulating the overall electric field distribution of the system, and improving the insulation performance of the composite film. Therefore, the breakdown strength of the PEN/BT@PDA composite dielectric material is increased, with the maximum breakdown strength being 180.9 kV/mm, which is a 14 % increase compared to the pure PEN film. Through calculation, the maximum energy storage density of the PEN/BT@PDA composite dielectric material is 0.78 J/cm 3 , which is an 81.4 % increase compared to the pure PEN. Under an external electric field of 120 kV/mm, the charge–discharge efficiency of the PEN/BT@PDA composite dielectric material can reach 69 %, demonstrating that BT@PDA can enhance the energy storage performance of PEN[30].

Separating oil-water emulsions in harsh conditions poses a substantial challenge for filtration membrane systems. In response, this study presented a continuous electrospinning technique to fabricate a robust bifacial composite membrane. Two types of high-performance polyarylene ether nitrile (PEN) polymers, PEN-BPA and PEN-B/P, with different wettability, are employed to construct the AB bifacial structure. Further, the A-side is modified with hydrophilic polydopamine (PDA) and antibacterial silver nanoparticles (Ag NPs) to prepare Ag@PDA/PEN-BPA, while the B-side is altered with photocatalytic titanium dioxide nanoparticles (TiO 2 ) to prepare TiO 2 /PEN-B/P. The resulting Ag@PDA/PEN-TiO 2 /PEN-B/P bifacial membrane demonstrates remarkable photocatalytic degradation efficiency, particularly for MB, reaching 99.8% degradation efficiency. Moreover, the permeation flux and oil-water emulsion separation rejection rate of the membrane reach 5180.34 L m − 2 ·h −1 and 99%. The PEN substrates are not only used to construct the AB bifacial structure but also to enhance the membrane's toughness and durability, ensuring stability in high-temperature and corrosive environments, with a rejection rate reaching 99% after 10 reuse cycles. Furthermore, integrating Ag NPs imparts excellent antibacterial properties to the membrane, sustaining a 99.99% antibacterial rate after oil-water emulsion separation, photocatalytic dye degradation, and exposure to high-temperature NaCl immersion. This study offers novel insights into multifunctional water treatment materials in harsh environments.

Polyesters are extensively utilized across various fields due to their superior physical and chemical properties; enhancing the toughness of polyesters is currently imperative for extending their applications. In this study, a novel acrylate elastomer (BMHx) with controllable hydroxyl groups was designed to melt-blend with polyethylene naphthalene (PEN), to enhance the fracture toughness of PEN. The hydroxyl group in BMHx can effectively enhance the compatibility of PEN and BMHx, thus reducing the average particle size of BMHx to endow it to disperse in PEN more uniformly, leading to a high toughness PEN material. The tensile toughness of PEN/BMH10 can reach 4.01 MJ/m3, and the notched impact strength is 8.02 kJ/m2, which are 18 times and 3.8 times higher than that of PEN, respectively. These findings provide a new strategy to toughen the polyester and thus a general usefulness.

Paper is ubiquitous in the daily life and has been widely used for writing and drawing because of their low-cost, widely accessible, and degradable properties. However, simple ways to fabricate paper-based optoelectronic devices remain a great challenge. In this work, we report a facile method to fabricate high-quality perovskite films and optoelectronic devices on paper by direct pen-writing. Through introducing seed layers on papers, planar-integrated single-crystal perovskite films are easily prepared using commercial pens. Based on such a simple and convenient method, perovskite photodetector arrays and image sensors with graphite electrodes are fabricated on paper, and show satisfactory performances. This method provides a simple and effective approach for preparation of paper-based perovskite devices. It will be of significance for the development of degradable optoelectronic devices.

Solar-powered interfacial evaporation technology is seen as a potential way to alleviate the crisis of water scarcity through seawater desalination. The key to the success of this technology hinges upon the efficient conversion of solar energy into heat energy, which is intimately connected with the innovative development of composite photothermal membranes. In this study, polyaniline (PANI) with excellent light absorption and carbon black (CB) with good stability were added to the polymer material polyaryl ether nitrile (PEN), and the PANI/CB-PEN nanofiber membrane was prepared by electrospinning blending. Due to the good stability of PEN polymer, the solar evaporator has excellent salt resistance and stability. The results show that the fiber membrane has the best light absorption effect when the reaction time is 80 min and the CB content is 50.0%. The composite fiber membrane temperature can reach 68.6°C, the evaporation rate is 1.51 kg m −2 h −1 , while the evaporation rate is 1.38 kg m −2 h −1 in a 3.5% NaCl brine. The photothermal conversion efficiency was 94.17%. The PANI/CB-PEN nanofiber membrane-based interfacial evaporation device demonstrates sustained performance in repeated tests, showing promising potential for long-term, scalable solar-powered seawater desalination applications.

As a typical triazole fungicide, penconazole (PEN) is widely used in agriculture but has been proven to be toxic. In this study, we designed a new hapten to prepare a highly sensitive and specific anti-PEN monoclonal antibody (mAb) and established a gold nanoparticle-based lateral-flow immunoassay (LFIA) for the detection of PEN residues in watermelon and cucumber. The 50% inhibitory concentration (IC50) of the mAb was 0.42 ng/mL and the LFIA strip had a visual limit of detection (vLOD) of 2.5 ng/g and a cut-off value of 10 ng/g in watermelon and cucumbers. The calculated limit of detection (LOD) of the LFIA strip was 0.36 ng/g for watermelon and 0.29 ng/g for cucumber. The LFIA strip also gave a recovery rate of 92.5%–109.0% for watermelon samples and 92.5%–106.7% for cucumber samples. These results using the LFIA strip are highly consistent with those seen using liquid chromatography–tandem mass spectrometry. Thus our developed LFIA strip represents a potentially reliable tool for the rapid on-site screening for PEN in watermelons and cucumbers.

The rapid development of the portable and wearable devices has inspired the ever-growing pursuit of flexible energy storage equipment which can power these devices. Here, rice paper (RP) was integrated with a homemade LGS-polypyrrole (LGS-PPy) ink and commercial pen ink in order to construct a flexible electrode of a supercapacitor via a facial dip-coating method. The obtained RP/LGS-PPy ink/Pen ink composites showed a high areal specific capacitance of 1568 mF/cm 2 at 0.2 mA/cm 2 , owing to the uniform deposition of a LGS-PPy layer which was covered by the pen ink coating. Furthermore, the assembled symmetric supercapacitor fabricated from the RP/LGS-PPy ink/Pen ink electrode exhibited impressive electrochemical performances in terms of specific capacitance (317.5 mF/cm 2 at 2 mA/cm 2 ), power density (846 μW/cm 2 at the energy density of 23.5 μWh/cm 2 ), and life times (82.1% capacitance retention after 5000 cycles). In addition, the capacitance of the as-prepared device remained essentially unchanged even after bending at 180°, thus demonstrating this device's outstanding flexibility. The low cost of raw materials, robust fabrication strategy as well as the moderate performances make the RP-based supercapacitor a promising candidate for future flexible energy storage devices.

In this study, we report a large-scale and facile synthetic method for silver nanoparticles via a microwave method, which is quite time-saving and efficient. The obtained silver nanoparticles maintained a uniform size, and the average size was less than 20 nm although the concentration of the silver source was very high. The obtained silver nanoparticles could be homogeneously dispersed in deionized water, which was beneficial for the fabrication of the conductive ink. For large-scale industrialization, the synthetic process window was widened to a great extent via a series of experiments. We injected the ink into a blank mark pen to fabricate a conductive pen, via which the tracks drawn on the photo paper could immediately become conductive at room temperature with an electrical conductivity of 2.4 μΩ cm (about 1.5 times that of the bulk Ag). The mechanical properties of the tracks were examined for a twistable application. After bending at a radius of 4 mm and 2 mm for 5000 circles, only a slight increase in their resistance of 1.20 and 1.78 relative to their initial resistance, respectively, was observed. The as-prepared conductive ink and fabricated pen have potential applications in flexible electronics.

Solar-driven interfacial water evaporation technology is recognized as a highly effective method for water purification. By incorporating photocatalytic degradation capabilities, it can further enhance the efficacy of wastewater treatment involving dye pollutants. In this study, poly(arylene ether nitrile) (PEN), a high-performance engineering plastic, was fabricated into a robust nanofibrous membrane substrate through electrospinning technology. The membrane was functionalized with polyaniline (PANI) through in-situ polymerization and subsequently doped with TiO 2 . As a result, dual-functional PANI/TiO 2 /PEN composite membranes were obtained, exhibiting properties suitable for solar-driven interfacial water evaporation and photocatalytic dye degradation. In this study, by modulating the surface morphology of PANI particles through involving in-situ growth on the PEN membrane using different surfactant pretreatments and varying HCl concentrations, a high evaporation rate of 3.17 kg m −2 h −1 was ultimately achieved. However, the dye removal rate reached 95.98% for methylene blue (MB) dye pollutant, owing to the adhesion of TiO 2 with photodegradation ability and the porous electrospun membrane with absorption properties. This study demonstrated high-efficiency water evaporation by modulating PANI morphology and offers a valuable strategy for constructing dual-functional nanofibrous membranes with both water evaporation and dye degradation capabilities for wastewater treatment applications. Graphical Creative application scenario schematic of the dual-functional PANI/TiO 2 /PEN electrospun nanofibrous membrane, which enables photothermal evaporation and photocatalytic degradation for highly efficient dye wastewater purification.

Friction and wear of pen nib steel in neutral ink systems is responsible for writing performance and service life. A water-based composite nanoparticle lubricant, (oleic acid-3-aminopropyltriethoxysilane-hyaluronic acid-titanium dioxide), named RNTH, was designed via a nuclear chain crosslinking method featured by shear-induced self-healing mechanisms in hydrogels. In comparison with traditional polyol lubricants, RNTH reduced the coefficient of friction by 17 %, wear mass loss by 28.3 %, and wear depth by 3–5 μm. Meanwhile, RNTH forms a dynamic lubrication layer at the friction interface, where the solid phase provides mechanical support and the liquid phase enables self-healing through hydrogen bond hydration, ensuring stable long-term lubrication. Importantly, this study introduces a biomimetic self-healing strategy to improve the durability of water-based lubricants under dynamic friction, offering new insights for designing high-precision liquid lubrication systems in industrial applications.

Flexible perovskite solar cells (f-PSCs) have achieved significant success. However, high-quality tin dioxide (SnO2) electron transport layers (ETLs) fabricated via chemical bath deposition (CBD) have not been achieved on flexible PEN/ITO substrates. This limitation is primarily due to the corrosion of the poor-quality ITO layer by the strongly acidic CBD solution. Here, we analyzed the reasons for the poor corrosion resistance of ITO films on PEN substrate from multiple perspectives, such as element composition, microstructure, and crystallinity. Then, we proposed a modified CBD method for SnO2 films suitable for flexible PEN/ITO substrates. We employed SnCl2·2H2O as the tin source and regulated the pH of the CBD solution by NH3·H2O, which effectively avoided the corrosion of the ITO layer by the CBD solution and achieved high-quality SnO2 films on the ITO layers. Compared to the commercial SnO2 dispersion, the SnO2 films prepared by this method have smaller grains and higher transmittance. As a result, we achieved an unprecedented power conversion efficiency (PCE) of 20.71% for f-PSCs fabricated on PEN/ITO substrates with SnO2 ETLs by CBD method. This breakthrough facilitates the development of high-performance f-PSCs by a low-cost and large-scale chemical bath deposition of high-quality ETLs on flexible substrates.
