Highly dispersive silver nanowires (AgNWs) in an epoxy matrix were obtained by introducing amino groups onto the surface of AgNWs. Firstly, modification of thioglycolic acid onto the surface of the AgNWs was conducted via coordination bonds between the AgNWs and thiol groups (AgNWs@COOH). Then amido-functionalized AgNWs (AgNWs@NH2) were prepared through an amidation reaction between triethylenetetramine (TETA) and the carboxyl groups. The chemical structure and properties of the AgNW–epoxy nanocomposites were investigated using TEM, EDS, FT-IR, UV, TAG, DSC and SEM. The results revealed that because the amino groups participated in the epoxy curing reaction, chemical bonds were formed at the interface to improve the dispersion of the AgNWs@NH2. Thus, the antistatic and thermal conductivity performances were enhanced by a well-constructed electrostatic discharge channel in the epoxy matrix. The surface resistivity of the AgNWs@NH2–epoxy nanocomposite was decreased to 1.24 × 105 Ω at 0.5 Vt%, and the thermal conductivity coefficient was upgraded to 0.67 W m−1 K−1 at 10 Vt%.

Though ionogels serve as a key component of wearable and intelligent sensing systems, they possess several characteristics that constrain their practical applications, including poor electro-mechanical synergy, insufficient interface synergy (resulting in low ion migration efficiency and conductive network fracture under large strains), scarce data labels, and inadequate long-term feature extraction capabilities in recognition systems. To address these issues, a new butanediol diacrylate/acrylic acid‑silver nanowire (BDAA/AgNWs) ionogel was synthesized using 365-nm ultraviolet (UV) polymerization, with 1-butyl-3-methylimidazolium chloride ([BMIM]Cl), 2-acrylamido-2-methylpropane sulfonic acid (AMPS), and acrylamide (AM) as the monomer-ionic liquid system, dimethyl sulfoxide (DMSO) as the solvent, and silver nanowires (AgNWs) as the filler. The ionogel formed a dual conductive network via metal-ionic liquid/monomer chemical coordination, had a conductivity of 1.394 S/m at 386.81% stretch, good stability, and biocompatibility. The outstanding mechanical properties of ionogel enable its use as a highly sensitive strain-resistive sensor. When mounted on the skin, mechanical deformations induced by facial expressions or joint movements stretch the internal conductive network, resulting in predictable and reproducible changes in electrical resistance. These resistance variations are captured via a voltage divider circuit and converted into digital signals through an analog-to-digital converter, providing a stable and reliable input for subsequent intelligent processing. To overcome existing accuracy limitations in motion recognition, an advanced algorithm integrating Transformer-based temporal feature extraction with triplet contrastive learning is employed. This end-to-end sensing-to-recognition framework enables the system to accurately interpret dynamic physiological signals, achieving a facial expression recognition accuracy of 97.62%—a 15% improvement over mainstream algorithms—and a 10% enhancement in action recognition performance. These results establish a robust foundation for the advancement of flexible, wearable intelligent sensing systems and next-generation human-machine interaction technologies.

Currently, silver nanowires (AgNWs) are among the most widely studied materials for flexible transparent electronics. Nevertheless, their practical implementation is hindered by inherent limitations in environmental stability and mechanical robustness. To address these challenges, this study presents a straightforward fabrication approach for a multifunctional flexible transparent conductive film (TCF) that exhibits superior mechanical integrity and long-term stability. Through simple solution processing, multiple functional layers were constructed on a flexible substrate. Among them, AgNWs serve as the conductive layer, SiO 2 NPs as the anti-reflection layer, and AZO as the protective layer. Accordingly, an AgNWs/SiO 2 /AZO TCF (ASZ) was fabricated, exhibiting a sheet resistance of 2.85 Ω/sq, a transmittance of 80.8% at 550 nm, and a figure of merit (FoM) value of 588. This TCF not only combines Joule heating and electromagnetic shielding but can also be used to fabricate OLED devices. A transparent Joule heating device fabricated from this TCF achieves a rapid thermal response, reaching 130 °C at 3 V while maintaining stable operation over extended durations. Furthermore, the film delivers an electromagnetic interference (EMI) shielding effectiveness of 32 dB across the X-band (8.2–12.4 GHz). Critically, owing to the outstanding oxidation resistance and superior surface planarity of the AZO layer, the film’s sheet resistance increases by only 24% after a rigorous 70-day aging test under ambient conditions. When employed as the anode in OLED devices, the TCF enables a maximum luminance of 17,400 cd/m 2 . Collectively, this work establishes a scalable, simple, and highly stable strategy for developing multifunctional transparent electronic devices.

The conductivity of AgNWs electrodes can be enhanced by incorporating Ag grids, thereby facilitating the development of large-area flexible organic solar cells (FOSCs). Ag grids from vacuum evaporation offer the advantages of simple film formation, adjustable thickness, and unique structure. However, the complex 3D multi-component structure of AgNWs electrodes will exacerbate the aggregation of large Ag particles, causing the device short circuits. To address this issue, the relationship between the surface energy of modification layers and the morphology and conductivity of ultrathin Ag on AgNWs is studied. The amorphous ZnO (α-ZnO) layer promotes Ag growth from Volmer–Weber (VW) to Frank–Van der Merwe (FM), reducing particle aggregation. The 1 µm thick PET/AgNWs/Ag grid electrode with α-ZnO exhibited low contact resistance and high conductivity. As a result, 1 cm 2 FOSCs with Ag grids achieve a power conversion efficiency (PCE) of 16.01%. As the area increased to 4 and 9 cm 2 , the performance of the monolithic FOSCs is 14.70% and 12.69%, showing less efficiency loss during upscaling. The 8 and 16 cm 2 modules constructed by series and parallel connection of the monolithic devices yield PCEs of 14.47% and 12.92%, respectively. This study offers valuable insights into constructing Ag grids on AgNWs electrodes for highly efficient large-area FOSCs.

Stretchable transparent electrodes (STEs) composed of highly conductive silver nanowires (AgNWs) and mechanically stretchable polydimethylsiloxane (PDMS) are compelling materials for the development of flexible electronic devices. So far, the fabrication processes of the AgNWs/PDMS-based STEs suffer from low efficiency on a small scale, apart from the limitations and challenges posed by the continuous fabrication processes that are required to exploit these fascinating materials in an industrial context. Here, we have addressed these limitations by using gradient PDMS with a tunable modulus as the stretchable substrate, on which ionic liquid-mediated aligned semi-embedded AgNWs are formed via a scalable superwettability-induced transfer strategy. We have demonstrated the importance of the gradient PDMS in achieving STEs with improved optoelectrical properties, mechanical stretchability, and long-term stability. Furthermore, we have shown the applications of the designed STEs for electro-heating and electroluminescent devices. This promising fabrication process is an industrially relevant alternative to current processes that are either complicated and less effective (for example, stamping transfer) or not compatible with continuous, large-scale production (for example, spin-coating or electrospinning).

African swine fever virus (ASFV) is a highly infectious and pathogenic DNA virus with a mortality rate of nearly 100%. Here, we developed a flexible biosensor based on a AgNWs/hydrogel/PS(polystyrene)/Fe 3 O 4 composite film for the detection of ASFV P72 protein gene fragments. A large number of carboxyl groups in the hydrogel provide modification sites for capture probes (cp) simplifying the preparation process of the biosensor. Combined with the excellent magnetic properties of Fe 3 O 4 , the excellent electrical conductivity of silver nanowires (AgNWs) and the unique optical properties of two-dimensional photonic crystals (2DPC), the flexible biosensor can convert biological signals into optical signals and electrical signals, and the micro-deformation of the film can be verified by simple optical methods. In order to improve the sensitivity, we introduce Fe 3 O 4 and apply an external magnetic field to amplify the thin film micro-deformation. The concentration of P72 protein gene fragment and the relative change rate of resistance showed a good linear relationship, and the linear equation is y = − 0.00126x − 0.31729; the detection limit (LOD) is as low as 0.208 μM. The composite film was used to detect real serum samples, and the recovery of the composite film fluctuated in the range 91.89 to 103.19%, indicating that the composite film has practical application potential in clinical detection of ASFV. In addition, the biosensor also shows good biocompatibility, stability, and specificity. Graphical

The presence of the toxic synthetic precursor and degradation product, 4-aminophenol (4-AP), in acetaminophen (ACOP) formulations poses significant health risks, necessitating robust analytical methods for quality control. Herein, a novel electrochemical sensor was developed based on a composite material synthesized by growing MOF-808 in situ on silver nanowires (AgNWs) via a one-pot method. The MOF-808/AgNWs composite synergistically combines the properties of both components, resulting in a sensor with excellent performance: wide linear ranges (0.1–400 μM), low detection limits (0.0175 μM for 4-AP and 0.0561 μM for ACOP), and high selectivity and stability. At the same time, the sensor also showed outstanding repeatability, reproducibility, stability and selectivity. The method was successfully applied to determine both analytes in pharmaceutical tablets and environmental water samples, achieving satisfactory recoveries. This work provides a simple, rapid, and highly sensitive platform for monitoring ACOP and 4-AP, holding great promise for pharmaceutical and environmental applications.

The widely used pesticide thiram is found in various environments and foodstuffs, posing a risk to human health and contaminating the environment. In this work, the novel SERS flexible sensor (FP/AgNWs@ZIF-8) consisting of silver nanowires and zeolite imidazole frameworks combined with filter paper was prepared for the sensitive and rapid detection of thiram on fruit peel surfaces. The effect that different coating cycles of ZIF-8 films exert on the Raman signal enhancement of the sensor was investigated. The results show that optimal Raman response to 4-Aminothiophenol (4-ATP) was demonstrated in the FP/AgNWs@ZIF-8(5) sensor, with a low LOD of 1.6 × 10 −15 M due to a coating period of 5. Furthermore, a novel SERS FP/AgNWs@ZIF-8 sensor with a porous and flexible structure on low-cost and eco-friendly paper was obtained, as to be immersed in a solution of thiram or wiped on a nectarine skin surface, and the highly sensitive LODs of 1.4 × 10 −12 M and 7.4 fg/cm 2 were achieved, respectively. Therefore, this facile, rapid, and sensitive flexible sensor at low-cost has excellent potential for pesticide residue detection and environmental toxicity analysis.

Phase change materials (PCMs) present promising potential in the application of thermal management. Nevertheless, low thermal conductivity and risk of liquid leakage hindered the development of PCMs with broad adoption. Here, we fabricate a shape-stable composite phase change material by encapsulating polyethylene glycol (PEG) into a dual-network hydrogel, which was modified using Ti 3 C 2 T x MXenes and silver nanowires (AgNWs). With the synergistic effect of MXene nanosheets and AgNWs, the composite material that was prepared demonstrates a significant increase in thermal conductivity, reaching a value of 0.64 (W/m·K) and also exhibits a suitable photo-thermal conversion efficiency (88.9%). Moreover, the resulting composite PCM with high-level of PEG loading (90.1%) deliver a remarkable phase change enthalpy (124.8 J/g), highlighting its excellent energy storage capability. Additionally, the final composite displays reliable structural stability and exceptional thermal management performance by reducing the operational temperature of a typical lithium-ion battery by over 12 °C during a 3C discharge process. We demonstrate a promising approach for developing composite PCM for thermal management.

MXenes show potential applications in sustainable energy due to their distinct layered structure, large surface area, adjustable surface chemistry and good conductivity, but the big challenge still remains in achieving both high specific capacitance and excellent stability. Herein, ternary strategy of 0D/1D/2D composite was proposed to realize high-performance supercapacitors (SCs) by synergy effect of silver nanoparticles and silver nanowires with Ti 3 C 2 T x . The enhancement in interlayer spacing, specific surface area and electrochemical conductivity resulted in abundant electrochemical active sites and improved ionic accessibility. Therefore, the ternary electrode exhibited excellent specific capacitance and superior cyclic stability, and it showed a specific capacitance of 796.6F g −1 at 2 mV s −1 , more than twice of 387.7F g −1 for Ti 3 C 2 T x . Moreover, the capacitance retention for ternary electrode was 98.2% after 10,000 CV cycles at 50 mV s −1 , comparable to 99.2% for Ti 3 C 2 T x . Furthermore, the symmetric SC with ternary electrode demonstrated specific capacitance of 109F g −1 at 2 mV s −1 with capacitance retention of 96.1% after 10,000 cycles, highlighting great potential for sustainable energy.

Silver nanowires (AgNWs) have attracted significant attention as an alternative to indium tin oxide (ITO) in flexible transparent conductive films (TCFs) due to their excellent electrical conductivity and high optical transmittance. However, AgNWs face numerous challenges in practical applications, including sparse linear arrangement leading to inter-wire gaps, thermal instability, and poor adhesion to substrates. To address these challenges, this study developed a CERGO/AgNWs/MXene multilayer sandwich-structured TCFs. Firstly, a conductive layer was formed by spin-coating MXene and AgNWs; secondly, a CERGO nano-protection layer was generated on the film surface via cathodic electrochemical reduction (CER). This method not only enhanced the film's stability and reduced sheet resistance but also improved electromagnetic interference (EMI) shielding performance while maintaining high optical transmittance. The prepared multifunctional TCFs exhibited a transmittance of 74.85% at 550 nm, a sheet resistance of 2.78 Ω/sq., and a figure of merit (FOM) of 435. Additionally, the film showed uniform heating performance, rapid thermal response, and high stability, reaching 131.4 °C at 4 V, and achieved an EMI shielding efficiency (SE) of 37.28 dB in the X-band (8.2–12.4 GHz). This study provides a new strategy for developing next-generation multifunctional TCFs with enhanced EMI shielding performance and thermal stability.

The selective separation and detection of benzene from toluene remains a critical challenge due to their structural similarity and the toxicity of benzene. In this work, we develop a novel composite substrate, PIZA-AgNW, consisting of a metal-organic framework (MOF), silver nanowires (AgNWs), and filter paper, fabricated via liquid-phase epitaxy (LPE). This substrate enables highly selective and real-time detection of benzene from toluene using tandem surface-enhanced Raman spectroscopy (SERS) and quartz crystal microbalance (QCM) analysis. The LPE method affords precise control of MOF thickness and pore structure, enhancing molecular selectivity for Raman detection. By correlating Raman intensity with QCM-derived mass changes, we achieve real-time monitoring of adsorption/desorption dynamics and quantify both equilibrium and nonequilibrium separation factors. Notably, a high equilibrium separation factor ( αₑ ) of 134 was obtained for a 1:1 benzene/toluene mixture. This work demonstrates a practical strategy for integrating structural selectivity with real-time sensing and offers broad potential for the dynamic monitoring of volatile organic compounds (VOCs) in environmental and industrial applications.
