Abstract In this study, we present a novel strategy in which carbon dots (CDs) are employed to induce the formation of crystalline domains and further fabricated super-strong hydrogels with high crystallinity, distinct anisotropic structures dense networks based on “pinning effect”, specifically, CDs act as nanofillers heterogeneous nucleating agents. As-prepared exhibited exceptional swelling resistance, ultra-high tensile strength (156 MPa) toughness (225.2 MJ m− 3), surpassing most other tough polymers, including natural tendons, plastic, synthetic rubber artificial spider silk, etc. Notably, hydrogel can support loads up approximately 1.5×105 times its own weight, highlighting their load-bearing capacity. Moreover, be generalized adapted environments more stringent mechanical loads. This work not only offers new insights into fabricating ultra-robust but also lays foundation for design development smart materials underwater sensing.

Abstract Aerogels excel in thermal insulation due to their porous structure, but limited mechanical strength restricts broader applications. Thus, the development of aerogel composites for equipment/personnel against and hazards extreme environments necessitates more design paradigm. Herein, a novel double‐crosslinked polyimide composite (PIAC) with an organic–inorganic hybridization approach is prepared. This composite, incorporating amino‐modified SiO 2 nanoparticles reduce shrinkage/density, offers exceptional from ‐110 °C 300 °C, flame resistance, low dielectric constant (1.4), conductivity 0.0357 W (m K) −1 self‐cleaning properties. Meanwhile, PIAC allows be manipulated into various shapes withstand repeated folding unfolding without damage. It boasts tensile 8.5 MPa (2.6‐fold enhancement) nominal elongation at break 54% (17.5‐fold enhancement), representing highest fracture toughness 32.99 × 10 6 kJ m −3 (47.8‐fold observed materials date. With maximum energy absorption reaching 7.46 MJ when dissipating high‐impact forces, its substantial enhancement capacity 60% over predecessor, not only bolster matrix also amplify strain rate strengthening effect. The fabricated poised foldable mechanical‐thermal‐coupled protection where such attributes are highly coveted.

Abstract Producing room temperature phosphorescent (RTP) materials from biomass resources using a solvent free method is essential but hard to achieve. Here, we discovered that lignin dissolved well in the liquid monomer, 2-hydroxyethyl acrylate (HEA), due extensive hydrogen bonding and non-bonding interactions between HEA. Motivated by this discovery, developed system consisting of HEA urethane dimethacrylate (UDMA) for converting into RTP materials. With design, generated radicals upon UV irradiation, which initiated polymerization (as monomer) UDMA crosslinker). The as-obtained polymer network rigidifies activates humidity/water-resistant with lifetime 202.9 ms. Moreover, afterglow color was successfully tuned red after loading RhB via energy transfer (TS-FRET). Using these properties, as-developed material used as photocured multiple-emission inks, luminescent coatings smart anti-counterfeiting logo medicine bottle.

Abstract Uncontrollable hemorrhage from deep, narrow wounds poses a critical threat to life, as locating the bleeding arteries in such areas is challenging. Rapid control remains significant challenge pre‐hospital care. Herein, an injectable hemostatic device filled with disc‐like PVA sponges developed for this objective. The pristine sponge strung necklace‐structured loaded foldable injector. With novel retraction mechanism, self‐designed injector precisely deploys deep sites, surpassing XStat TM design innovation. sponges' high porosity and unique porous structure allowed it rapid shape recovery (<30 s) good compressive strength. In punctured wound, swollen exert compression close artery, resulting fast‐bleeding control. pig groin femoral artery injury model, treatment resulted 100% survival rate during 2‐h hemostasis period, compared 33.3% cotton gauze group. addition, can be easily taken out by simple pulling. applicable removable highly promising hemostat wounds.
