Demands of the strong integrated materials have substantially increased across various industries. Inspired by relationship excellent integration mechanical properties and hierarchical nano/microscale structure natural nacre, we developed a strategy for fabricating artificial nacre based on graphene oxide (GO) sheets dopamine cross-linking via evaporation-induced assembly process. The tensile strength toughness simultaneously show 1.5 2 times higher than that nacre. Meanwhile, shows high...
Aqueous Al-ion batteries (AAIBs) are the subject of great interest due to inherent safety and high theoretical capacity aluminum. The abundancy easy accessibility aluminum raw materials further make AAIBs appealing for grid-scale energy storage. However, passivating oxide film formation hydrogen side reactions at anode as well limited availability cathode lead low discharge voltage poor cycling stability. Here, we proposed a new AAIB system consisting an AlxMnO2 cathode, zinc...
Abstract Ion is one of the most common additives that can impart electrical conductivity to insulating hydrogels. The concurrent toughening effect ions, however, often neglected. This work reports extreme hydrogels via synergistic cations and anions, without need for specific structure design or adding other reinforcements. strategy equilibrate a physical double network hydrogel consisting both multivalent cation‐ kosmotropic anion‐sensitive polymers in salt solutions induce cross‐linking...
Abstract Swelling is ubiquitous for conventional hydrogels but not favorable many situations, especially underwater applications. In this study, an anti‐swelling and mechanically robust polyacrylic acid (PAAc)/gelatin composite hydrogel reported with a rapid gelation process (10 1 s) under mild conditions via the synergy of MXene‐activated initiation zirconium ion (Zr 4+ )‐induced cross‐linking, without requirement external energy input. The MXene found efficient to activate chain...
Abstract Human beings cannot live without elastomers, which exist almost everywhere in human life nowadays. Although elastomers with a variety of features are developed for specific applications, timeless topic is how to toughen them, because mechanical properties always determine the reliability and lifespan utilized elastomers. Toughening soft material has long history main idea widely accepted, i.e., building energy dissipation into stretchy networks. Double network (DN) method most...

Abstract The development of hydrogel‐based underwater electronics has gained significant attention due to their flexibility and portability compared conventional rigid devices. However, common hydrogels face challenges such as swelling poor adhesion, limiting practicality in water environments. Here, a water‐induced phase separation strategy fabricate with enhanced anti‐swelling properties adhesion is presented. By leveraging the contrasting affinity different polymer chains water,...

With its synergistic toughening effect and hierarchical micro/nanoscale structure, natural nacre sets a "gold standard" for nacre-inspired materials with integrated high strength toughness. We demonstrated strong tough ternary bioinspired nanocomposites through of reduced graphene oxide double-walled carbon nanotube (DWNT) covalent bonding.

Soft fiber-reinforced polymers (FRPs), consisting of rubbery matrices and rigid fabrics, are widely utilized in industry because they possess high specific strength tension while allowing flexural deformation under bending or twisting. Nevertheless, existing soft FRPs relatively weak against crack propagation due to interfacial delamination, which substantially increases their risk failure during use. In this work, a class that simultaneously showing extraordinary resistance developed. The...
Non-adhesive hydrogels are tailored to show tough adhesion various solid surfaces by a universal phase-separation method. This method opens the possibility of utilizing non-adhesive for emerging soft–rigid hybrid devices.
High modulus, toughness, and fatigue resistance are usually difficult to be obtained simultaneously in rubbery materials. Here, we report that by superimposing the nanophase separation structure double network (DN) elastomers using immiscible polymers, fracture energy, energy release rate of threshold enhanced all together 13, 5, 5 times, respectively. We reveal interplay between DN brings two effects synergistically: (1) formation nanoclusters overstresses homogenizes sacrificial network,...
