Polymers are often used as adhesives to improve the mechanical properties of flexible electromagnetic interference (EMI) shielding layered films, but introduction these insulating inevitably reduces EMI performance. Herein, ultrafine aramid nanofibers (UANF) with a diameter only 2.44 nm were binder effectively infiltrate and minimize gaps in MXene for balancing properties. Combining evaporation-induced scalable assembly assisted by blade coating, large-scale MXene/UANF films highly aligned compact stacking successfully fabricated. Compared conventional ANF larger 7.05 nm, UANF-reinforced film exhibits "brick-mortar" structure higher orientation compacter nanosheets, thus showing properties, electrical conductivity, By optimizing content, can achieve optimal tensile strength 156.9 MPa, toughness 2.9 MJ m

Abstract Biomaterial‐based flexible electromagnetic interference (EMI) shielding composite films are desirable in many applications of wearable electronic devices. However, much research focuses on improving the EMI performance materials, while optimizing comprehensive safety materials has been neglected. Herein, cellulose nanofiber@boron nitride nanosheet/silver nanowire/bacterial (CNF@BNNS/AgNW/BC) with sandwich structure fabricated via a simple sequential vacuum filtration method. For first time, electrical safety, biosafety, and thermal optimized integratedly. Since both sides contain CNF BC insulation layers, CNF@BNNS/AgNW/BC exhibit excellent safety. Furthermore, benefiting from AgNW conductive networks middle layer, effectiveness 49.95 dB ultra‐fast response Joule heating performance. More importantly, antibacterial property ensures biosafety films. Meanwhile, CNF@BNNS layers synergistically enhance conductivity film, reaching high value 8.85 W m ‒1 K , which significantly enhances its when used miniaturized device. This work offers new ideas for fabricating biomaterial‐based

Flexible pressure sensors are intensively demanded in various fields such as electronic skin, medical and health detection, wearable electronics, etc. MXene is considered an excellent sensing material due to its benign metal conductivity adjustable interlayer distance. Exhibiting both high sensitivity long-term stability currently urgent pursuit MXene-based flexible sensors. In this work, high-strength methylcellulose was introduced into the film increase distance of 2D nanosheets fundamentally overcome self-stacking problem. Thus, concurrent improvement capability mechanical strength obtained. By appropriately modulating ratio MXene, obtained sensor presents a 19.41 kPa–1 (0.88–24.09 kPa), good (10000 cycles), complete biodegradation H2O2 solution within 2 days. Besides, capable detecting wide range human activities (pulse, gesture, joint movement, etc.) can precisely recognize spatial distribution, which serves candidate for next-generation devices.

With the rapid development of electronic information technology, composite materials with outstanding performance in terms electromagnetic interference (EMI) shielding and strain sensing are crucial for next-generation smart wearable devices. However, fabrication flexible films dual functionality remains a significant challenge. Herein, multifunctional exciting EMI properties were constructed using facile vacuum-assisted filtration process transfer method. The consisted ultrathin AgNW/MXene (Ti3C2Tx)/AgNW conductive networks (1 μm) attached to polydimethylsiloxane (PDMS) substrate. obtained AgNW/MXene/PDMS film exhibited an exceptional effectiveness 50.82 dB good flexibility (retaining 93.67 90.18% its original value after 1000 bending stretching cycles, respectively), which attributed enhanced multilayer internal reflection network created by AgNWs MXene as well synergistic effect PDMS. Besides shielding, also displayed remarkable properties. They wide linear range tensile up 68% gauge factor 468. showed fast response, ultralow detection limit, high mechanical stability. Interestingly, could detect motion voice recognition, demonstrating their potential sensors. This study highlights resisting radiation monitoring human motion, thereby providing promising solution devices complex environments.
