With the flourishing of mussel-inspired chemistry, the fast-growing development for environmentally friendly materials, and the need for inexpensive and biocompatible analogues to PDA in gel design, TA has led to its gradual emergence as a research focus due to its remarkable biocompatible, renewable, sustainable and particular physicochemical properties. As a natural building block, TA can be used as a substrate or crosslinker, ensuring versatile functional polymeric networks for various applications. In this review, the design of TA-based gels is summarized in detail (i.e., different interactions such as: metal coordination, electrostatic, hydrophobic, host-guest, cation-pi and pi-pi stacking interactions, hydrogen bonding and various reactions including: phenol-amine Michael and Schiff base, phenol-thiol Michael addition, phenol-epoxy ring opening reaction, etc.). Subsequently, TA-based gels with a variety of functionalities, including mechanical, adhesion, conductive, self-healing, UV-shielding, anti-swelling, anti-freezing, shape memory, antioxidant, antibacterial, anti-inflammatory and responsive properties are introduced in detail. Then, a summary of recent developments in the use of TA-based gels is provided, including bioelectronics, biomedicine, energy, packaging, water treatment and other fields. Finally, the difficulties that TA-based gels are currently facing are outlined, and an original yet realistic viewpoint is provided in an effort to spur future development.

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 ：
Flexible hybrid nanogenerators (HNGs) have received significant attention for their potential in harvesting mechanical energy to power portable and miniaturized portable devices. This work presents a method to fabricate flexible, durable and biodegradable electrospun polydopamine@barium titanate/cellulose acetate (PDA@BTO/CA) nanofiber films. This design integrates polydopamine (PDA) and piezoelectric barium titanate (BTO) nanoparticles within a flexible cellulose acetate (CA) matrix to enable self-powered wearable biomonitoring. The inclusion of PDA enhances the physical adhesion between BTO and CA, resulting in a significant 40% increase in voltage output. Notably, the PDA-modified composite PDA@BTO/CA demonstrates remarkable durability over 15,000 cycles and effectively detects a range of human motions (such as fist clenching, wrist bending, elbow movement, walking, running and jumping), transducing them into stable, precise electrical signals. Intriguingly, the hybrid nanogenerator device exhibits robust performance in extreme conditions, including underwater and high or low temperatures, while maintaining its good biodegradability. This work paves the way for advanced self-powered wearable biosensor devices capable of precise and reliable human motion monitoring.

Abstract ：
Developing multifunctional interfacial materials is critical in solving the poor interfacial contact and severe charge recombination in perovskite solar cells (PSCs). Here, based on low-cost green biomass cellulose, pyridine with varied N-positions is incorporated to produce esterified cellulose C-m-Py and C-p-Py as the electron-selective interface layer between tin oxide (SnO2) and perovskite. It was found that C-m-Py with the N atom at the meta-position shows a higher dipole moment and wellmatched energy alignment compared to C-p-Py. Importantly, C-m-Py can simultaneously enhance the conductivity of SnO2 and passivation capacity toward perovskite, leading to improved interfacial charge extraction efficiency. Consequently, the C-m-Py-based PSCs deliver a remarkably high efficiency of 24.35%, along with excellent thermal stability. This study demonstrates a facile and cost-effective way to design efficient interfacial materials by the simple functionalization of renewable sources in nature.

Abstract ：
A novel sulfur-and fluorine-containing dianhydride monomer 2,2-bis[4-(3,4-dicarboxyphenylthio)phenyl]hexafluoropropane dianhydride (6FDAPSA) was synthesized by molecular design, and a series of random co-polyimides were prepared from 6FDAPSA, 4,4-(hexafluoroisopropene)diphthalic anhydride (6FDA) and 4-(3-fluoro-4-(trifluoromethyl)phenyl)-2,6-bis(4-aminophenyl)pyridine (FTPPA). The obtained co-polyimides exhibited excellent thermal properties (T-g > 288 degrees C, T-5 % > 504 degrees C, T-10 % > 536 degrees C), good optical properties (lambda(cut-off) > 342 nm, lambda(80 %) > 410 nm), commendable mechanical properties (tensile strength >75 MPa) and outstanding hydrophobic properties (contact angle >90.0 degrees). They also showed excellent solubility in both high and low boiling point organic solvents. Besides, Wide-angle X-ray diffraction test and molecular simulation confirmed that the prepared co-polyimides possess a large molecular chain spacing, with d-spacing values ranging from 5.59 to 5.84 & Aring; and fractional free volume from 0.237 to 0.280. Consequently, polyimide membranes exhibited commendable gas permeability values of He (up to 49.5 barrer) and CO2 (up to 34.2 barrer), and good ideal gas selectivity values of He/N-2 (up to 34.2) and CO2/N-2 (up to 22.2). These results indicate that polyimide matrix materials have potential application prospects in the field of gas separation.

Abstract ：
Hydrogel electrolytes have gained considerable attention as key components in flexible supercapacitors for electronic devices. However, traditional hydrogels face challenges due to inadequate mechanical properties and low energy density in supercapacitor applications. In this study, a highly conductive and flexible hydrogel (PAA-LS-Al3+) composed of polyacrylic acid (PAA), lignosulfonate (LS), and Al3+ was fabricated. The optimal ratio of LS to water, along with specific amount of AlCl3 center dot 6H2O contributed to rapid polymerization redox pairs of Al3+/ Al2+ and hydroquinone/quinone, thus facilitating hydrogel preparation. High concentrations of LS and Al3+, along with effective Al3+ complexes, endowed the hydrogel with ionic conductivity of 5.80 S center dot m-1, tensile strength of 420.64 kPa at 830 % elongation, and compressive strength of 2860 kPa with strain of 99.87 %. When assembled into a supercapacitor with moisture content of 25.12 %, the specific capacitance of hydrogel electrolyte exhibited 306.19 F center dot g-1, maximum energy density of 27.22 Wh center dot kg-1, and power density of 2398.39 W center dot kg-1. After 5000 cycles, the supercapacitor maintained capacitance retention of 78.1 % and a coulombic efficiency of 99.8 %. The PAA-LS-Al3+ hydrogel with long lifespan and good stability showed great potential for practical applications in flexible power supplies.

Abstract ：
In this study, a novel diamine 4-(2,6-bis(4-(trifluoromethyl)phenyl)pyridine)phenyl-3,5-diaminobenzoate (FPPAB) containing trifluoromethyl, pyridine, and ester groups was synthesized by a three-step organic reaction. Then, four structures of copolyimides were prepared by a one-step polycondensation reaction using diamine (FPPAB), dianhydride 4,4 '-(hexafluoroisopropyl)diphthalic anhydride (6FDA), and four commercial diamines. The synthesized copolyimides exhibited high thermal stability, with the glass transition temperature (T-g) and 5% loss temperature (T-5%) in the range of 210 degrees C-256 degrees C and 343 degrees C-452 degrees C, respectively, and X-ray diffraction analysis indicated that the copolyimides featured a d-spacing of 4.90-5.57 & Aring;. They also showed excellent solubility in both high and low boiling point organic solvents. Furthermore, the membranes not only had outstanding optical properties (wavelength range of 80% transmittance = 378-454 nm) but also had excellent hydrophobicity (water contact angle > 91.96 degrees). Notably, the copolyimide membrane with a fluorene structure showed the highest gas permeability (P(He) = 46.27, P(CO2) = 21.06, P(N-2) = 1.57 barrer) and favorable selectivity (alpha(He/N-2) = 29.55, alpha(CO2/N-2) = 13.69). This membrane also exhibited the largest fractional free volume (FFV). Overall, the prepared copolyimides exhibited a well-balanced combination of properties, particularly in gas separation performance, indicating that the properties of copolyimides could be effectively optimized by adjusting the structure of monomers.

Abstract ：
As a natural polymer, cellulose has emerged as a promising candidate for constructing versatile materials and products due to its intrinsic biocompatibility, environmental degradability, and structural stability. As a state-ofthe-art output, cellulose ionogel has demonstrated advanced applications in various scenarios in the Internet-of-Things era, while the weak mechanical strength is significantly challenging. To address this limitation, we developed a simple self-crosslinked stagey of cellulose molecules by triggering the chemical reactions of the hydroxyl and dialdehyde groups. Such chemical bonds between cellulose molecules create the tough selfcrosslinked cellulose-ionogel (SCCell-ionogel), which demonstrates super high strength of 4.23 MPa with 540 % improvement, toughness of 1.36 MJ/m3 with a 900 % increase. In addition, the resultant SCCell-ionogel also features high transmittance (93 %) and desirable biodegradation. The self-crosslinked strategy paves the way for constructing high-performance, advanced ionogel of natural polymer for next-generation smart materials.

Abstract ：
Adhesive patches are optimum candidates for distinct biomedical applications, including tissue adhesion and leakage sealing in outpatient or surgical procedures. Unfortunately, most adhesive patches are significantly less effective at providing strong adhesion to the surface of wet tissue, which increases the risk and reduces the fault tolerance in surgery. Meanwhile, customization is difficult to achieve in terms of mechanical adaptability. To tackle this problem, we developed a chitosan-containing bioadhesive patch (ANC) comprising dual-crosslinked carboxymethyl chitosan methacrylate (CMCS-MA), acrylic acid, and acrylic acid N-hydroxysuccinimide ester. This ingenious and convenient design strategy facilitates the integrated polymerization of the patch, while circumventing the necessity for additional crosslinkers. ANC patches in dry state and the rich carboxyl groups contained therein enable rapid removal of moisture from tissue surfaces. Subsequently, robust adhesion based on hydrogen bonding and N-hydroxysuccinimide (NHS)-amine interaction is formed. The dual-crosslinked ANC patch achieves good adjustable mechanical performance and swelling behavior by controlling the addition of CMCS-MA. Furthermore, compared with commercially available fibrin glue, ANC patches own robust adhesion and superior sealing performance for stomach fluid leakage. This intricately designed ANC patch sheds new light on biomedical patch design and broadens the scope of chitosan-containing materials in tissue adhesive and sealant applications.

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.
