Abstract ：
Multifunctional wearable flexible electronic devices based on hydrogels have received extensive research in recent years. Despite their promising applications, a significant challenge persists in terms of efficiently powering these devices. Triboelectric nanogenerators (TENGs) assembled by surface-modified hydrogels may be one of the promising strategies to address this challenge. This study presents the development of a multifunctional composite hydrogel, which is synthesized through the amino surface modification of glycerin-cellulose hydrogel (3-aminopropyltriethoxysilane-glycerin-cellulose, A-GC). The resulting composite hydrogel is utilized in the fabrication of electrodes of TENGs, which can effectively harvest mechanical energy to power flexible sensors. By using cellulose and glycerin as primary raw materials and 3-aminotriethoxysilane as surface modification components, the composite hydrogel exhibits excellent mechanical properties, coupled with good electrical conductivity (2.83 S/m). More importantly, it exhibits a high triboelectric output performance of 205.3 V, maintains stable long-term triboelectric output, and achieves a maximum triboelectric power density of 732.1 mW/m2. Furthermore, the introduction of glycerin into the cellulose hydrogel enhances its mechanical properties and triboelectric output performance even under extreme environmental conditions (-24 and 60 degrees C). The A-GC-TENG demonstrates significant potential in various applications, including mechanical energy harvesting and conversion, writing recognition, wireless signal transmission, and human-computer interaction, showing great application prospects in flexible wearable sensors and self-powered electronic devices. The development of the composite cellulose hydrogel offers a novel approach for the fabrication of high-performance flexible wearable electronic devices, which is capable of functioning effectively in harsh environments.

Abstract ：
With the backdrop of the rapid advancement in supercapacitor technology, biomass hydrogel electrolytes have emerged as a prominent research focus. This study systematically optimized critical parameters using a multi-component synergistic strategy, the glycerol (Gl) as an antifreeze agent, to develop a ligninsulfonate (LS) dual-network antifreeze hydrogel suitable for low-temperature-resistant supercapacitors. The P(AA-co-AM)/LS/Al3+/Gl hydrogel exhibited remarkable mechanical properties, with tensile stress reaching 751.01 kPa and strain of 1050 %. The assembled supercapacitor demonstrated a specific capacitance of 244.5 F g−1 at room temperature under a current density of 0.2 A g−1. After 5000 charge-discharge cycles, the capacitance retention rate remained 80.16 %, with a coulombic efficiency exceeding 98.5 %. Moreover, at −80 °C, the hydrogel assembled supercapacitor achieved a specific capacitance of 167.2 F g−1; retaining certain electrochemical performance across various bending angles. This research provides valuable insights into the development of biomaterial-based antifreeze electrolytes for extreme environments. © 2025 Elsevier Ltd

Abstract ：
Cellulose-based hydrogels are promising materials for constructing flexible supercapacitors and energy storage devices due to their environmental sustainability and resource renewability. However, preparing cellulose-based hydrogel electrolytes with super flexibility, high conductivity, and high specific capacitance for practical applications is still challenging. Herein, an adhesive, antibacterial, conductive zwitterionic cellulose nanofibersreinforced poly(sulfobetaine methacrylate-acrylic acid-acrylamide (ZCNF/PSAA) composite hydrogel was fabricated by a blue light-triggered free radical polymerization of 2-methacryloyloxy ethyl dimethyl-3sulfopropyl ammonium hydroxide (SBMA), acrylic acid (AA), acryl amide (AM), dopamine methacrylamide (DMA) and zwitterionic cellulose nanofibers (ZCNF). The prepared hydrogel exhibited excellent mechanical properties with tensile strength of 0.17 MPa, compressive strength of 0.87 MPa, and shear strength of 1.25 MPa, respectively. The zwitterionic groups significantly enhanced the hydrogel's conductivity (5.8 S/m). Moreover, the hydrogel with electrically sensitive perception of external strain (GF = 2.5), can withstand large bending and compression deformations and can be used as a motion sensor to monitor human movements such as arm and finger bending, pressing, and subtle fist clenching. The resulting hydrogel presented excellent antibacterial activity against Escherichia coli and Staphylococcus aureus. As the hydrogel was applied as electrolyte, the developed super-capacitor exhibited a desirable specific capacitance of 404.5 mF.cm-2, with a maximum energy density of 53.93 Wh.kg-1 and capacitance retention of 80.3 % after 2000 consecutive charge-discharge cycles. The ZCNF/ PSAA hydrogel has great potential for applications in flexible strain sensors and energy storage devices.

Abstract ：
Wearable sensing electronic devices based on hydrogel are gradually developing towards multifunction and portability, however, efficiently harvesting energy from the surrounding environment to power traditional hydrogel-based wearable electronic devices is a major challenge. The assembly of multilayer heterogeneous hydrogels is a potential strategy to address this challenge. Herein, inspired by the structure of diodes, a diode-like integrated hydrogel composed of a three-tier structure of anionic polyelectrolyte hydrogel, polyacrylamide hydrogel and cationic polyelectrolyte hydrogel is developed. By the connection of polyacrylamide hydrogel, the composite hydrogel exhibits excellent structural stability and mechanical properties. Notably, due to the introduction of MXene ion-conducting microchannels, the directional transport of free cations and anions ionized by anionic and cationic polyelectrolytes is achieved, thereby improving the conductivity (74.58 mS/cm), sensing (gauge factor = 7.47) and piezoionic output performance of the composite hydrogel. The composite hydrogelbased sensor can sense tiny facial movements and recognize the direction of human movement, and the composite hydrogel-based piezoionic generator exhibit more efficient mechanical-electric conversion performance, which can output the maximum voltage of 1410 mV, current of 28 mu A, and power density of 2.9 mW/m2 for a composite hydrogel of 5x5 cm2. The integration of multilayer heterogeneous hydrogels proposes a versatile strategy for the development of high-performance hydrogel-based self-powered sensing electronic devices, expanding the application of hydrogels in artificial intelligence and human-computer interaction.

Abstract ：
Biochar materials, known for their low cost, abundant availability, green environmental protection and renewable nature, are extensively applied across the energy storage sector. However, their structure and inherent limitations of the raw materials greatly reduce their energy storage performance. In this research, we aimed to optimized the structure of Melaleuca leucadendron L. bark activated carbon (BAC) by adjusting the ball milling time and speed. We also explored the optimal composite mass ratio of BAC/polyaniline (PANI) and further enhanced the electrochemical performance of the pseudocapacitive material composite employing in-situ polymerization techniques with ferric chloride doping for PANI. The characterization of BAC/PANI composites was performed through scanning electron microscopy (SEM), nitrogen adsorption-desorption isotherms (BET), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR). The BAC/PANI electrode materials' electrochemical capabilities and supercapacitor functionality were tested using cyclic voltammetry (CV), galvanostatic charge-discharge analysis (GCD), and electrochemical impedance spectroscopy (EIS). The study demonstrated that ball milling not only mended defects in amorphous carbon but also increased crystallinity and oxygen content. Additionally, the presence of PANI contributed nitrogen atoms. The functional groups with oxygen and nitrogen content improved the electrode materials' wettability, which contributed to the pseudo-capacitive effect and subsequently increased electrochemical performance. The BAC/PANI-FeCl3-10 material exhibits a defined capacitance of 414.0 F g- 1 at a current density of 0.5 A g- 1, and maintained a capacity retention rate of 74.7 % after 5000 cycles, with an energy density output of 5.2 Wh kg- 1 at a high-power density of 1872.0 W kg- 1. This research provides a theoretical and empirical foundation for the utilization of bark activated carbon as an electrode material in supercapacitors, paving the way for more efficient and sustainable energy storage solutions.

Abstract ：
Bamboo fiber (BF) reinforced composites are attractive for sustainable engineering, yet their performance is hindered by weak fiber-matrix adhesion, the brittleness of the epoxy, and pronounced creep under warm and humid conditions. This study reported the synergistic strengthening and toughening achieved by impregnating long bamboo fibers with a polydopamine (PDA) primer that immobilized 20 nm alumina (Al2O3) nanoparticles (3 wt%) prior to epoxy infusion. The engineered interphase raised flexural strength, modulus, and impact toughness to 161.92 MPa, 9897.73 MPa, and 26.35 kJ/m2, gains of 23.5 %, 22.2 %, and 20.1 %, respectively; while the glass transition temperature rose from 58.1 oC to 67.3 oC. Short-term flexural-creep tests (120 min) conducted at three stress levels (25 %, 50 %, and 75 %), temperatures (25 oC, 50 oC, and 75 oC) and relative humidities (25 %, 50 %, and 75 %) revealed markedly improved creep resistance, as evidenced by lower deflection, higher creep modulus and extended endurance. Stress exerted the dominant influence, followed by temperature, and then humidity, whose combined action accelerated creep and fracture. A six-parameter viscoelastic model captured the creep response more accurately than the classical four-element model. These findings provide a quantitative basis for predicting service life and designing reliable bamboo-fiber composites in structural applications.

Abstract ：
With the rapid advancement of flexible, portable devices, hydrogel electrolytes have gained considerable attention as potential replacements for conventional liquid electrolytes. A hydrogel electrolyte was synthesised by cross-linking acrylic acid (AA), acrylamide (AM), carboxymethyl cellulose (CMC), and zinc sulphate (ZnSO4). 4 ). The formation of hydrogen bonds and chelate interactions between the P(AA-co-AM) co-AM) polymer, CMC, and ZnSO4 4 created a robust network, enhancing the mechanical properties of the hydrogel electrolytes. Notably, the hydrogel electrolyte containing 0.6 % CMC demonstrated superior mechanical strength (compression strength of 1.22 MPa, tensile stress of 230 kPa, tensile strain of 424 %, adhesion strength of 1.98 MPa on wood). Additionally, the CMC/P(AA-co-AM) co-AM) hydrogels exhibited commendable electrical performance (38 mS/cm) and a high gauge factor (2.9), enabling the precise detection of physiological activity signals through resistance measurements. The unique network structure of the hydrogel electrolyte also ensured a stable bonding interface between the electrode and the electrolyte. After 2000 charge-discharge cycles, the supercapacitor maintained good capacitance characteristics, with a capacitance retention rate of 71.21 % and a stable Coulombic efficiency of 98.85 %, demonstrating excellent cyclic stability. This study introduces a novel methodology for fabricating multifunctional all-solid-state supercapacitors and suggests that the hydrogel can significantly advance the development of wearable energy storage devices.
