Abstract The development of multifunctional bio‐adhesive plays a critical role in achieving sustainable society, where the intrinsic sensitivity to water and poor dynamics severely bottlenecks its scale‐up application. Inspired by microstructure dragonfly wings, strong tough adhesive with excellent reprocessability is designed developed creating dynamic network consisting lignin polyurea (LPU) framework soybean protein (SP). LPU act as rigid nervures slow crack propagation transfer stress, while SP dissipate strain energy through interplay from graded hydrogen imine bonds generated between SP. achieves significant enhancements fracture toughness resistance ≈7 23 folds, respectively, compared Furthermore, capacity for diffusion restoration endows superior reprocessability, enabling recycled particleboard achieve high retention modules (over 80%). This approach offers promising eco‐friendly alternative conventional petrochemical adhesive.

Abstract Cellulose nanofibers (CNFs) are ideal building blocks for creating lightweight and strong bulk structural materials due to their unique supramolecular structure exceptional mechanical properties within the crystalline regions. However, assembling CNFs into dense with customizable shape functionalities remains a great challenge, hindering practical applications. Here, dewatering issue of aqueous CNF dispersions is addressed by regulating scale hydrophilicity using lactic acid, combined hot‐press molding. This approach enables fabrication transparent density up 1.426 g cm −3 . The properties, including isotropic in‐plane tensile strength (75.5 ± 4.5 MPa), flexural (198 20 hardness (≈300 surpass most engineering plastics. Moreover, unlike conventional based materials, exhibit remarkable water stability flame retardancy. These advantages open new avenue bottom‐up assembly high‐performance multifunctional eco‐friendly dedicating substitution plastics easing consumption petrochemical resources.

Natural polymeric-based bioplastics usually lack good mechanical or processing performance. It is still challenging to achieve simultaneous improvement for these two usual trade-off features. Here, we demonstrate a full noncovalent mediated self-assembly design simultaneously improving the chitinous bioplastic and properties via plane hot-pressing. Tannic acid (TA) chosen as mediator (i) increase cross-link intensity obtaining tough network (ii) afford dynamic cross-links enable mobility of chitin molecular chains benefiting nanostructure rearrangement during shaping procedure. The multiple (chitin–TA chitin–chitin cross-links) pressure-induced orientation nanofibers structure endow with robust properties. relatively weak chitin–TA interactions serve water mediation switches enhance endowing chitin/TA hydroplastic properties, rendering them readily programmable into versatile 2D/3D shapes. Moreover, fully natural resourced exhibits superior weld, solvent resistance, biodegradability, enabling potential diverse applications. physical cross-linking mechanism highlights an effective concept balancing processability polymeric materials.

Abstract Lithium–Sulfur (Li─S) batteries are renowned for their high theoretical specific capacity and cost‐effectiveness. Nevertheless, performance could be impeded by obstacles including lithium dendrite growth polysulfide (LiPS) shuttle, particularly under harsh conditions. Herein, an economical strategy is reported modifying polyolefin separators (PP) with covalent organic polymer networks (TPE) to alter Li solvent structure, enhance lithium‐ion transport, suppress shuttle effects. Combining in situ/ex situ characterization calculations, it demonstrated that the lithiophilic groups (‐C═N‐) TPE@PP separator form strong interaction lithium, facilitating dissociation of Li─Solvent/LiPS‐solvent release freer ion shape a stable solid electrolyte interface rich LiF 3 N. The network serves as “highway” accelerates transport promotes uniform nucleation behavior. Therefore, Li|TPE@PP|CNT/S cell enables 60% retention after 2000 cycles at 1.0 C exhibits cycling 100 from ‐40 80 °C. Moreover, pouch maintains more than 600 mA h g −1 30 0 This study provides promising avenue application high‐performance environment perspective engineering.
