Abstract Intelligent impact‐protection wearable devices often require intricate circuitry to operate, which hinders the timely display of impact‐related injuries. Consequently, it is imperative develop intelligent protective materials that are self‐sufficient and capable visualization. In this work, impact protection material shear‐stiffening gel (SSG) combined with mechanoluminescent (ML) ZnS:Cu/PDMS@SiO 2 create ML‐SSG. This embodies various features, including protection, force visualization, flame resistance, long‐distance passive control, making ideal for devices. light significant shear stiffening effect SSG, ML‐SSG effectively dissipates up 80% energy exhibits excellent resistance. Concurrently, also visualizing injuries, displaying warning in real‐time via mechanoluminescence, assessing based on intensity mechanoluminescence. The incorporation SiO ZnS:Cu has resulted remarkable flame‐retardant property. innovative significantly improves performance complex environments. addition, realizes human–computer interaction through neural network mechanoluminescence characteristics. research expands potential applications multifunctional complicated environments, thereby promoting development

Ceramic nanofibrous aerogels exhibit ultralow density and thermal conductivity, which make them ideal candidates for protection in extreme environments. However, the current limitations pore-forming techniques hinder their further advancement. In this study, ultralight, highly elastic, high-temperature-resistant ceramic were successfully prepared through direct foaming method using flexible Al2O3–SiO2–B2O3 nanofibers as raw materials Tween 80 agent. Foams generated slurry exhibited exceptional stability, facilitating formation of a porous three-dimensional network structure with nonoriented pores tightly bonded fiber connections within green body after drying process. This was obtained via sintering maintained stability at temperatures up to 1000 °C. addition, porosity controlled by adjusting content An increase dosage resulted higher number air bubbles per unit volume slurry, accompanied decrease sizes. Consequently, possessed abundant small sizes, promoting gradual deterioration junctions. As result, demonstrated elasticity well improved insulation properties. These findings provide novel insights preparation performance regulation aerogels.

Abstract In this study, we present a facile and sustainable approach to developing sodium alginate/phytic acid bioaerogels, aiming enhance their thermal insulation flame‐retardant properties. The results reveal that 1% phytic concentration is optimal, resulting in significant reduction conductivity 0.040 W/mK, while also improving specific heat capacity diffusivity. Mechanical tests indicate at concentration, the aerogels achieve superior structural integrity, evidenced by enhanced hardness, resilience, cohesiveness, which are critical for maintaining performance under mechanical stress. Furthermore, bioaerogel exhibited excellent flame retardance, achieving UL‐94 V‐0 rating Limiting Oxygen Index (LOI) of 35%, demonstrating its resist ignition slow down propagation. contrast, with higher concentrations acid, particularly 2.5%, displayed instability, leading incomplete gelation failure maintain coherent aerogel matrix. These findings underscore importance optimizing balance thermal, mechanical, fire‐retardant properties, thereby enhancing practical applications bioaerogels as eco‐friendly materials. Highlights Optimized boosts W/mK. Sodium alginate rating. Phytic ensures stability high resilience. High (>1%) leads reduced porosity instability. Eco‐friendly show resistance.
