Organic–inorganic composite aerogels represent a novel class of materials that effectively combine the advantages of both organic and inorganic components. Polybenzoxazine (PBz) has emerged as a promising organic alternative due to its structural rigidity, thermal stability, and cost-effectiveness. However, achieving efficient compatibility between PBz and inorganic components remains a significant challenge. In this study, inspired by the structure of diatoms, tannic acid (TA) was introduced as a compatibilizer to stabilize the dispersion of inorganic silica precursors within a PBz solution and improve their compatibility. A uniform structure with minimal phase separation was achieved through a two-step catalytic copolymerization method at room temperature. Benefiting from the inherent rigidity of PBz and superior thermal stability of polysiloxane, the resulting polybenzoxazine/silicon hybridized aerogel (BSA) exhibits a low thermal conductivity of 0.0487 W m−1 K−1, a high compressive strength exceeding 20.0 MPa, and outstanding thermal degradation stability (Td5 of 389.75 °C). This biomimetic and environmentally sustainable approach holds significant potential for advancing the development of next-generation thermal insulation materials.

Dual-ion batteries have got significant attention in recent years due to their efficient ion insertion mechanism, abundant electrode material options, and chemical stability, showcasing advantages such as high operating voltage, low cost, and enhanced safety. Organic electrode materials are often used in dual-ion batteries due to their designability and high theoretical capacity. However, the compatibility between organic electrode materials and current collectors affects the cycling and capacity performance of dual-ion batteries. In this paper, a novel thin film structure of sulfuric acid-doped polyaniline composite copper oxide is electropolymerized on the surface of copper foil current collector. The synergistic effect of electropolymerization-driven oxidation and copper oxide templating facilitates the formation of doped polyaniline nanoparticles, transforming the polymer into long-range ordered crystalline structures with a particle size of 10 nm. Because of the crystalline nanostructure of doped polyaniline and copper oxide, there is an interface change between the anode and active material during charge–discharge cycles, reducing the internal charge transfer resistance from 112 to 40 Ω. While the dual-ion battery shows a significant improvement at high rates, experiments show that the dual-ion battery still retains a capacity of 44 mAh g −1 after 2000 cycles at 5 C, with a capacity retention rate of 69.7%, but the capacity of dual-ion battery without the modification current collectors is only 12 mAh g −1 after 2000 cycles at 5 C. The paper discusses the mechanism of the smallest size composite polyaniline material and the influence mechanisms on the performance of dual-ion batteries. Graphical

This research introduces an innovative waterborne intumescent epoxy coating (P-S-IEC) reinforced by in-situ polymerized polyaniline-silicon carbide (PANI-SiC) hybrids, which simultaneously achieves the dual functions of flame retardancy and corrosion protection. The PANI-SiC hybrids are chemically grafted, synergistically combining the thermal insulation properties of SiC nanosheets with the passivation and char-forming abilities of PANI. Large-scale combustion tests show that the P-S-IEC coating maintains its structural integrity even after being exposed to a 1200 °C flame for 120 min, with an impressively low backside temperature of 289 °C. This performance significantly surpasses that of control coatings containing either PANI or SiC alone. Electrochemical analysis further reveals its outstanding corrosion resistance: after immersion in a 3.5 % NaCl solution for 20 days, the charge transfer resistance ( R ct ) remains as high as 7.43 × 10⁷ Ω·cm², and the corrosion current density is only 2.23 × 10⁻⁸ A/cm². The enhanced flame retardancy of the P-S-IEC coating can be attributed to the thermal insulation provided by SiC and the intumescent char expansion of PANI, which together form a stable three-dimensional carbon layer with reduced microporosity. Regarding corrosion protection, the coating benefits from the tortuous path effect of SiC, which hinders ion penetration, and the electrochemical passivation of the steel substrate induced by PANI. This study offers a scalable approach for developing multifunctional coatings that integrate passive shielding and active protection mechanisms. It effectively addresses key challenges in ensuring structural fire safety and long-term corrosion resistance for various industrial applications.

Driver fatigue is a major cause of traffic accidents, significantly impairing attention and reaction time. Traditional detection methods typically rely either on visual data or sensor signals. Image-based approaches suffer from lighting variations, while sensor-based methods are prone to noise interference. Here, a multimodal fusion architecture that integrates visual imagery with tactile signals from flexible sensors using porous composites is proposed to detect driver fatigue states. A convolutional neural network extracts features from the images, while sensor signals are encoded through fully connected layers. The extracted representations are then projected into the same dimensional space for concatenated feature fusion. Experimental results show that the proposed multimodal approach improves recognition accuracy by more than 4% compared with single-modality methods and generalizes reliably across varied appearances and extreme conditions. Furthermore, a detailed evaluation and quantification of fatigue levels have been conducted, which contributes to accident prevention and promotes driving safety.

The precise detection of nitrite as a stable, end product and downstream metabolite of NO is critical for understanding exercise-induced physiological adaptation in athletes. However, typical electrochemical techniques usually have restricted sensitivity, photointerference, and matrix-dependent inaccuracy when detecting biological samples. In this work, we fabricated a PEC platform exploiting an ultrahigh-photocurrent CdS/polyaniline (CdS/PANI) heterostructured film to facilitate accurate and selective nitrite detection as a biologically important health parameter of exercise-induced NO metabolism. When the CdS quantum structure is combined with the conductive PANI, strongly increased visible light absorption efficiency and more rapid charge separation were achieved, and electron-hole recombination was inhibited. Such synergistic effects result in strong photocurrent responses, with nitrite being an efficient electron acceptor and contribute to a substantial concentration-dependent reduction of the photocurrent. It provides an acceptable limit of detection, a wide linear range, good selectivity toward the traditional biological interferents, and stability during use. The proposed CdS/PANI PEC system offers a rapid, cost-effective, and analytically powerful strategy for evaluating exercise-induced metabolic changes and highlights its strong potential for future applications in sports physiology, biomarker detection, and personalized performance monitoring.

The integration of high energy density and robust mechanical flexibility in electrode materials remains a fundamental challenge for flexible energy storage devices. While manganese dioxide (MnO₂) offers high theoretical capacitance, its inherent rigidity and poor conductivity severely limit practical applications. Herein, we propose an innovative “rigid-flexible complementary” multi-level design strategy, constructing a multifunctional PVA-SA-PPy@MnO₂-PANI composite hydrogel. This architecture ingeniously integrates hollow-structured PPy@MnO₂ microspheres for enhanced active sites and electrolyte permeability, a dual-conductive-polymer network (PPy and PANI) for efficient electron transport, and a dynamic hydrogen-bonding matrix (PVA and SA) that confers remarkable mechanical strength (megapascal-level), exceptional flexibility, and intrinsic self-healing capability. The resulting hydrogel serves not only as a high-performance electrode for all-gel-state flexible supercapacitors, delivering an outstanding areal energy density of 10.4 mWh/cm 2 and excellent capacitance retention under extreme bending, but also as an effective tribo-positive layer in single-electrode triboelectric nanogenerators (TENGs), enabling stable energy harvesting. This work demonstrates a breakthrough material platform that successfully unifies high energy density, superior mechanical properties, self-healing, and dual energy storage/harvesting functionalities, paving the way for next-generation flexible and wearable electronics.

Aqueous zinc ion batteries (AZIBs) offer safe and environmentally friendly features, making them attractive energy storage devices. A critical challenge in the development of AZIBs is the search for cathode materials capable of delivering stable and efficient performance. Therefore, the quest for reliable cathode materials has become a pressing priority for advancing this technology. Conductive polyaniline (PANI) is a favorable candidate due to its excellent electrical conductivity, diverse redox chemistry, and doping-de-doping mechanism. To boost the electrochemical performance of PANI as a cathode in ZIBs, we fabricated a binary doped PANI using H 2 SO 4 and ammonium lauryl sulfate (ALS). The synergy of the binary doping approach endows H 2 SO 4 /ALS-PANI with good conductivity, better structure and morphology. As a result, binary doped PANI demonstrates robust electrochemical performance in AZIBs. In a full Zn cell, the H 2 SO 4 /ALS-PANI cathode exhibited an exceptional specific capacity of 269.58 mAh g -1 at 0.5 A g -1 and retained 223.52 mAh g -1 at 5 A g -1 , showing excellent rate performance (82.91%). Moreover, it demonstrated promising cyclic stability with 97.68% capacity retention after 4,000 galvanostatic charge-discharge (GCD) cycles, maintaining coulombic efficiency (CE) close to 100%. Electrochemical impedance spectroscopy (EIS) indicate that H 2 SO 4 /ALS-PANI has low charge transfer resistance (R ct ). This study provides inspiring dual doping strategy for developing conducting polymers electrode materials for AZIBs.

Wearable sensors based on gels have attracted considerable attention owing to their immense promise for applications in healthcare monitoring, electronic skins, and human-machine interfaces. However, it remains challenging to design multifunctional gel-based sensors that integrate resilience, self-healing, adhesion, anti-swelling, and reliable underwater sensing properties. In this work, a poly(lipoic acid- co -acrylic acid- co -tannic acid)/polyaniline (PLAT-P) organogel was developed via a facile one-pot radical copolymerization strategy. The resulting organogel exhibits high resilience (95% at 600% strain), outstanding self-healing efficiency (99% for 24 h), robust underwater adhesion (107 kPa on aluminum), and excellent anti-swelling performance (9.4% mass change after 28 d). The combination of dynamic disulfide bonds and abundant hydrogen bonds in organogel network contributes to the self-healing capability, while the incorporation of lipoic acid and tannic acid imparts robust adhesion even in underwater environments. Strain sensor based on the organogel demonstrates high sensitivity (gauge factor of 8.2), excellent cycling stability, and reliable repeatability. It can accurately monitor human motions across a wide strain range and also function as a dependable Morse code transmitter for underwater communication. This work offers a promising strategy for the wearable sensors in extreme conditions.

Efficiently integrating solar and ambient thermal energy within a single molecular system remains a significant challenge. Here we systematically construct a family of azobenzene-based molecules in which photoisomerizable cores are covalently coupled with thermally active alkyl and alkenyl segments. Unlike previous studies focusing on isolated examples, our approach establishes a homologous molecular series that enables direct correlation between structural parameters and dual-mode energy storage behavior. Upon ultraviolet irradiation, the trans -cis isomerization induces lattice disorder and photo‐liquefaction, allowing simultaneous capture of photon energy and latent heat. The reverse process triggered by light or heat releases both chemical and phase-change enthalpies in a single synergistic step. The system exhibits a gravimetric energy density exceeding 300 J g −1 , demonstrating a competitive performance among reported materials. Combined density functional theory and calorimetric analyses quantitatively link the isomerization energetics with crystal packing variations, establishing a predictive relationship between molecular design and thermophysical performance. This systematic strategy provides a data-driven framework for designing programmable photothermal materials and paves the way for high-throughput molecular energy computation.

Morphological and size control of Pt nanoparticles (PtNPs) has long been pursued to improve the catalytic performance of Pt-based electrochemical sensors during recent decades. In this study, a high‑performance hydrogen peroxide sensor was developed by electrochemically depositing PtNPs onto a polyaniline‑modified glassy carbon electrode (PANI/GCE). Subsequently, the PtNPs/PANI/GCE electrode was separately subjected to two distinct methods, namely square wave (SW) treatment and square wave voltammetry (SWV). It was found that SWV was able to alter the exposed surface of platinum nanoparticles from (111) to (200), which leads to the formation of the angular nano-edges on the original Pt nanospheres. This structural transformation effectively increased the number of active sites and enlarged the effective surface area for the catalytic redox reaction of hydrogen peroxide. Owing to such advantages, the prepared PtNPs/PANI/GCE-SWV electrode exhibits a wide linear range from 50 μM to 30 mM and an excellent sensitivity of 294.90 μA·mM −1 ·cm −2 for H 2 O 2 detection. In addition, SWV endowed the fabricated sensor with superior stability and reproducibility, thereby demonstrating promising prospects in the commercialization of stretchable and wearable biosensors.

The relatively weak interfacial adhesion existed between poly (ether ether ketone) (PEEK) and carbon fiber (CF) and is a constantly problem that restricts the mechanical performance and structural- functional integrated design of CF/PEEK composites. To meet with the interface stable and multifunctional demands of high-performance CF/PEEK composites, an organic- inorganic combination strategy was proposed to synchronous optimize the interfacial adhesion and electromagnetic interference (EMI) shielding performance of CF/PEEK composites. Herein, conductive polyaniline (PANI) was in-situ polymerized onto MXene, along with carbon nanotubes to prepare a mixture sizing agent to coat CF surface. The synergistic enhancement effects of interfacial interactions, mechanical interlocking, and wettability contributed to the elevated interfacial and mechanical properties of CF/PEEK composites. Besides, evenly coated sizing layers enhance the conduction loss, interfacial polarization loss and dipole polarization loss at interface, which led to a remarkable improvement in EMI shielding performance of CF/PEEK composites. In brief, this facile and feasible route to obtain PANI@MXene/CNTs sizing agents displays a considerable potential in fabricating CF/PEEK composites possessed the structural- functional integrated performance.

Low hysteresis and mechanical toughness are important to improve the accuracy and timeframe of use of flexible sensors.However, constructing conductive flexible sensors with high mechanical strength, low hysteresis, and high toughness simultaneously remains a challenge. In this work, we construct an entangled crosslinked topological network with physical interactions to fabricate conductive flexible sensors with high mechanical properties, toughness, and hysteresis. Predeacetylated Chitin nanocrystals (ChNCs) were grafted onto epoxidized natural rubber (ENR), and then PANI was polymerized in situ. ChNCs with amino groups serve as templates for ANI polymerisation and provide junctions in the crosslinked network, enhancing molecular chain entanglement and crosslinking. Upon loading, molecular chain conformations spontaneously adjust to equilibrium. Meanwhile, hydrogen bonds and electrostatic interactions with low strength exist between the polymer matrix and conductive fibres, which could rapidly break and reform during cyclic deformation. Therefore, the synergistic interaction of topology network and physical interaction endows materials with high mechanical properties (2.5 MPa, 1000%) and low energy dissipation ratio (13.6% in 300% cyclic strain) and hysteresis (13.3% in 300% cyclic strain). This work shows an effective method to prepare conductive flexible sensors with high toughness, high strength and low hysteresis for human body signals detection. The sensor shows a good electrical response to external stress, which can be used to monitor the movement of human joints. This work develops an effective strategy for manufacturing tough conductive sensors exhibiting low hysteresis, high toughness, and strength, indicating potential for healthcare technologies.
