Abstract Developing conductive hydrogels with both high strength and fracture toughness for diverse applications remains a significant challenge. In this work, an efficient toughening strategy is presented that exploits the multiple enhancement effects of anions through synergistic combination mineralization, salting‐out, ion coordination. The approach centers on hydrogel system comprising two polymers cation highly responsive to anions. Specifically, polyvinyl alcohol (PVA) chitosan quaternary ammonium (HACC) are used, as PVA benefits from salting‐out HACC undergoes coordination multivalent After just 1 h immersion in anionic solution, dramatic improvement mechanical properties, increasing by more than three orders magnitude. optimized achieves (26 MPa), Young's modulus (45 remarkable (67.3 kJ m −2 ), representing enhancements 860, 3200, 1200 times, respectively, compared its initial state. This breakthrough overcomes typical trade‐off between stiffness toughness. Additionally, ionic conductivity enables reliable strain sensing supports development durable supercapacitors. work presents simple effective pathway developing exceptional strength, toughness, conductivity.

Abstract Multi‐stage porous aerogels have spurred relentless innovation and surpassed traditional boundaries by redefining the landscape of advanced sound management technologies. Harnessing stress‐responsive tuning properties in intricately enhances acoustic attenuation. porosity provides enhanced efficiency across a variety environments. In addition to facilitating attenuation, demonstrating exceptional flame resistance represent an innovative solution specifically engineered for high‐temperature applications. this study, biomimetic multi‐stage aerogel, BMPA, is developed created through mild microbial fermentation, resulting distinctive internal structure. BMPA enabled as high 93%, with ultralight density 0.0518 g cm − 3 . The uncompressed material reduced levels at 1.5 kHz and, when stretched, further improved attenuation 2, 2.5, kHz. Its multistage pore structure lowered noise from 85.7 68.7 dB, achieving total reduction 17 dB—an impressive advancement management! treated inorganic zinc solutions demonstrates significant resistance, V‐0 rating limiting oxygen index value exceeding 60%. groundbreaking development significantly potential next‐generation materials that excel absorption.
