A flexible laterally-configured electrochromic supercapacitor was designed and fabricated through a fully-solution process. The laterally-configured transparent conductive electrode PEDOT:PSS-AgNWs/PET was prepared by spraying technology and then the magenta electrochromic polymer (PProDOT) and gel electrolyte were cast sequentially onto the laterally-configured electrode. The as-prepared device exhibits alternative color changes between magenta and transparent within the potential range −0.9 V and 0.9 V, and the electrochromic behavior is retained even if bent, proving its excellent flexible display properties. As expected, a “ZJUT” patterned flexible display device works clearly when applying driving potentials to the two circuits simultaneously. In addition, the asymmetric device (PProDOT||PEDOT:PSS) integrates excellent electrochromic and electrochemical energy storage properties in terms of high optical contrast of 59.5 %, large coloration efficiency of 423.5 cm 2 ·C −1 , fast switching time (7.4 s and 3.9 s), reasonable areal capacitance of 2.15 mF/cm 2 at a current density of 0.05 mA/cm 2 and robust cyclic stability which can retain 85.65 % and 77.42 % of its initial optical contrast and capacitance even after 1000 cycles of mechanical deformation. Hence, this work demonstrates the flexible laterally-configured electrochromic supercapacitor has great potential in the portable and wearable display fields, such as smart watches and electronic paper.

Surface modification for boiling heat transfer enhancement can boost the operational efficiency of energy systems and resolve thermal management challenges in electronic devices. However, the concurrent optimization of critical heat flux (CHF) and heat transfer coefficient (HTC) remains challenging. This is because it demands a delicate balance between facilitating bubble nucleation and suppressing detrimental bubble coalescence. To address this, concurrent improvement of the two parameters during boiling was achieved by spraying AgNWs (Ag nanowires) synthesized through a modified polyol method onto a microgroove substrate, thereby preparing Ag nanowire-coated microgroove surfaces (MG-AgNWs). The pool boiling characteristics, capillary wicking and bubble dynamics of MG-AgNWs under atmospheric pressure were systematically investigated. The as-prepared MG-AgNWs surface achieves a CHF of 349.9 W cm −2 and an HTC of 26.2 W cm −2 K −1 , corresponding to enhancements of 269.4% and 759.8% compared with the plain copper surface, respectively. Benefiting from the enhanced capillary performance of AgNWs and the excellent nucleation activity of MG, the MG-AgNWs surface exhibited significantly increased nucleation density, reduced bubble departure diameter, and accelerated bubble departure frequency compared with plain copper substrates. Capillary wickability tests on various surfaces demonstrated a strong linear correlation between wicking velocity and CHF. These results confirm that capillary-driven liquid replenishment inhibits dry spot expansion, leading to improved CHF. Collectively, such hierarchical surface presents a viable approach to creating efficient boiling heat transfer surface for advanced thermal control applications.

Conductive hydrogels, owing to their flexibility, high biocompatibility, tissue-mimetic properties, and electrical responsiveness, hold broad application prospects in fields such as flexible biosensing, wearable electronics, and health monitoring. However, constructing continuous and stable conductive pathways while maintaining biocompatibility and mechanical stability remains a key challenge in the design of such materials. In this study, we combined template casting with a chemical welding strategy to fabricate patterned AgNWs-GelMA conductive hydrogels. The results indicate that chemical welding effectively improves the connection quality at AgNWs intersections, increasing the electrical conductivity of the samples by at least 67% under identical conditions. Furthermore, the conductive hydrogel exhibited good biocompatibility. Flexible sensors constructed from this material generated stable electrical responses to external stimuli, such as pressure and joint motion. Under a constant cyclic pressure of 0.2 N, the sensors exhibited a rapid total response and recovery time of 200 ms, demonstrating their potential for flexible biosensing applications, particularly under conditions of small deformation.

Hydrogel flexible sensors have demonstrated significant potential in human motion and health monitoring applications; however, their practical implementation is constrained by poor anti-swelling performance and limited recyclability. In this study, a gradient assembly strategy combining freeze-thaw, salting-out, and swelling (FSS) was developed to fabricate an anti-swelling PVA/AgNWs hydrogel with closed-loop recyclability. This synergistic phase separation approach enables simultaneous optimization of mechanical properties, electrical conductivity, and anti-swelling performance. Relative to control hydrogels undergoing solely freeze-thaw cycles, the FSS-processed PVA/AgNWs hydrogel exhibited a 61-fold increase in bulk toughness (from 0.031 MJ/m 3 to 1.9 MJ/m 3 ) and a 6-fold enhancement in conductivity (from 0.041 S/m to 0.25 S/m). Moreover, after 15 days of water immersion, the hydrogel maintained exceptional stability: mass change remained below 5%, while tensile strain, bulk toughness, and electrical conductivity exhibited over 95% retention after both 7 and 15 days. Leveraging the physical nature of cross‑links (hydrogen bonds and crystals), we established a complete closed-loop recycling system. After three cycles of recycling, the hydrogel retained 95% tensile strain, preserved 91.52% of the original tensile stress, and maintained 97.71% of the initial conductivity. Additionally, the hydrogel exhibited excellent biocompatibility and antibacterial properties. Sensors based on this hydrogel achieved underwater biomimetic motion monitoring, while biological electrodes performed comparably to commercial Ag/AgCl electrodes in human physiological signal acquisition. The green, low-cost, sustainable gradient assembly strategy provides a universal methodology for balancing mechanical robustness, electrical conductivity, and environmental adaptability in next-generation wearable electronics, thereby advancing technological breakthroughs and industrial upgrades in sustainable flexible electronics.

Carbon fibers (CF) have triggered extensive interest with the progress of multifarious marine electric field sensor devices owing largely to their high flexibility, good conductivity and exceptional chemical/thermal stability. Herein, flexible Ag/sliver nanowires (AgNWs)/CF (Ag-AgNWs-CF) electrodes with extremely tiny potential difference drift of 67.22 μV/24 h have been successfully fabricated by a facile alcohol-thermal method with a reaction temperature of 170℃ for 120 min. The conductive AgNWs was introduced to the CF as a coating material. The AgNWs with three-dimensional (3D) network and silver particles accounts for superior areal specific capacitance and low Tafel slope for the composite electrodes (CEs). Using such flexible Ag-AgNWs-CF as a marine electric field sensor, the excellent self-noise was obtained, which signifies prospective ability to respond to weak signals.

The majority of the current composite core–shell structure preparation and sintering processes applied to silver nanowire transparent electrodes are impractical for large-scale industrial production and primarily emphasize macroscopic performance parameters, with limited insights into the underlying sintering mechanism. This study presents a simple synthesis of AgNWs@PVP core–shell structures and investigates the effects of sintering temperature and time on their morphology. The morphology of AgNWs@PVP core–shell structures during sintering was systematically analyzed using characterization techniques, such as transmission electron microscopy and scanning electron microscopy. Subsequently, a comprehensive understanding of its sintering mechanism was summarized. This provides theoretical foundation for the preparation of AgNWs-based core–shell structures and high-temperature sintering based on core–shell structures.

A novel, operational, reliable, flexible gas sensor based on silk fibroin fibers (SFFs) as a substrate was proposed for detecting the freshness of pork. Silk is one of the earliest animal fibers utilized by humans, and SFFs exposed many biological micromolecules on the surface. Thus, the gas sensor was fabricated through polyaniline (PANI) and silver nanowires (AgNWs) and deposited on SFFs by in-suit polymerization. With trimethylamine (TMA) as a model gas, the sensing properties of the PANI/AgNWs/silk composites were examined at room temperature, and the linear correlativity was very prominent between these sensing measures and the TMA measures in the range of 3.33 μg/L–1200 μg/L. When the pork sample is detected by the sensor, it can be classified into fresh or stale pork with the total volatile basic nitrogen (TVB-N) as an index. The result indicated that the gas sensor was effective and showed great potential for applications to detect the freshness of pork.Keywords:polyaniline;silver nanowires;silk;trimethylamine;gas sensor;pork freshness

Flexible transparent conductive thin films (TCFs) prepared from Silver nanowires (AgNWs) have attractive features of low cost, flexibility, and solution-processed, but the usual manufacturing methods could still be hard to be scaled up. In addition, large-scale/large-area fabrication process with industrialized potential is strongly needed. In this paper, the flexible TCFs with high stability are obtained via using screen printing method to print the AgNWs inks on a flexible and transparent substrate. The micro-structure of the AgNWs patterns is investigated by optical microscope and scanning electron microscope. Furthermore, the sheet resistance, light transmittance, and film thickness of the AgNWs patterns prepared under different conditions are characterized to explore the influence of different factors on its optical and electrical properties.

Abstract As application scenarios and usage conditions become increasingly complex, traditional indium tin oxide materials are limited in meeting diverse application demands due to their low flexibility and high cost. This study proposed a ternary nanocomposite strategy combining zero-dimensional AgNPs, one-dimensional AgNWs, and two-dimensional graphene oxide (GO) nanosheets to fabricate transparent conductive films (TCFs) with excellent environmental stability and optoelectronic properties, suitable for applications such as Joule heating, electromagnetic interference (EMI) shielding, and organic light-emitting diode (OLED) devices. By growing AgNPs in situ on the surface of GO, combined with a simple solution-processing technique and integration with silver nanowires (AgNWs), this study developed GO-AgNP/AgNW TCFs featuring a dual-layer structure. Test results showed that the TCF achieved a sheet resistance of 2.98 Ω/sq, a light transmittance of 78.6% at 550 nm, a haze of 11.5%, and a figure of merit of 0.0302 Ω−1. The TCF also exhibited outstanding environmental stability, with no significant change in resistance after 50 days of aging tests. When used as a Joule heating device, it reached a maximum temperature of 110 °C under a working voltage of 2.5 V, demonstrating a fast thermal response. As an EMI shielding device, it achieved a shielding effectiveness of 27 dB in the X-band (8.2−12.4 GHz). Notably, when employed as the anode in OLED devices, the GO-AgNP/AgNW TCF enabled excellent electroluminescent performance, achieving a maximum luminance (Lmax) of 10,000 cd/m2, a maximum current efficiency (C.E.max) of 12.4 cd/A, a maximum power efficiency (P.E.max) of 5.6 lm/W, and a maximum external quantum efficiency (EQEmax) of 3.7%. This work provides a scalable approach for developing TCFs with simple fabrication processes, superior environmental stability, and multifunctionality, effectively meeting the demands of complex and dynamic application environments.

To promote the construction of the thermal network in the epoxy resin (EP), a certain proportion of silver nanowires (AgNWs) coupled with the hexagonal boron nitride (BN) nanoplates were chosen as fillers to improve the thermal conductivity of EP resin. Before preparing the composites, BN was treated by silane coupling agent 3-aminopropyltriethoxysilane (KH550), and AgNWs was coated by dopamine hydrochloride. The BN/AgNWs/EP composites were prepared after curing, and the thermal conductivity and dielectric properties of the composites was tested. Results showed that the AgNWs and BN were uniformly dispersed in epoxy resin. It synergistically built a thermal network and greatly increased the thermal conductivity of the composites, which increased 9% after adding AgNWs. Moreover, the electrical property test showed that the addition of AgNWs had little effect on the dielectric constant and dielectric loss of the composites, indicating a rather good electrical insulation of the composites.Keywords:epoxy resin;boron nitride;silver nanowires;thermal conductivity

Among metals, AgNWs are considered to be excellent materials for use in surface enhancement Raman spectroscopic (SERS) sensing due to their superior electrical properties, strong electromagnetic field generation and strong enhancement intensity. Herein, we used a simple conventional polyol method to synthesize AgNWs feasibly in 40 min under Ar inert atmosphere without using any inorganic salts; only high molecular weight PVP was used as a capping and growth controlling agent, while ethylene glycol was used as a solvent as well as a reducing agent and silver nitrate was used as a Ag source. The polyol-synthesized smooth surface AgNWs were then subjected to chemical etching using aqueous ammonia and 30% hydrogen peroxide as etchant materials, and corrugated surface AgNWs were successfully prepared. The as-synthesized corrugated surface AgNWs were used as surface enhancement materials to increase the intensity of Raman signals, and the surface enhancement properties of the corrugated surface AgNWs were studied using rhodamine 6G as a probe molecule via SERS sensing. The results showed that the AgNWs were successfully prepared in 40 min of reaction; also, corrugated surface AgNWs were prepared, and their corrugated surfaces resulted in high intensity SERS signals.

Developing stable and efficient electrocatalysts for hydrogen evolution reaction is of great significance for the production of clean hydrogen energy from water splitting. In this work, 3D AgNWs@NiMo/PU electrode was obtained by electrodepositing NiMo alloy onto three-dimensional silver nanowires conductive substrate (3D AgNWs/PU) which was uniformly assembled on the surface of the skeleton of a polyurethane sponge (PU). 3D AgNWs/PU provides good electrolyte permeability, rich active site attachment points, good electronic conductivity and electrocatalytic synergy, which greatly improves the catalytic activity. In addition, 3D AgNWs@NiMo/PU electrode does not need to use adhesive in the process of hydrogen evolution, which can improve the hydrogen evolution performance and stability of the electrode. Specifically, the optimized electrode (AgNWs@NiMo/PU-1200 s) exhibits excellent hydrogen evolution performance by achieving a low overpotential of 32 mV (vs. RHE) at a current density of 10 mA cm −2 , with a Tafel slope of 72 mV dec -1 (in 1 M KOH). More interestingly, it also has good stability after 10 h of stability test. Therefore, this study provides a feasible way to develop stable and efficient 3D HER electrocatalysts.
