Abstract Excellent mechanical flexibility, thermal conductivity, and microwave absorption are essential properties for multifunctional materials applied in next‐generation wearable electronics. However, it remains a great challenge to improve the incompatibility among these properties. Herein, high‐quantity V 2 O 5 @NaV 6 15 @PPy core‐shell nanofibers (CSNFs) synthesized via simple dissolution‐recrystallization situ redox polymerization process. Owing regular, periodic, stable sensing signals, their membrane can serve as strain sensor accurately detect word pronunciation body movement. Their TPU films possess high strength, excellent hydrophobicity, large conductivity (3.56 W m −1 K ); 7 wt.% load. Besides, CSNFs exhibit efficient wide‐band (8.56 GHz) RCS reduction (24.41 dBm ) at low load (7 wt.%), outperforming most other absorbers. The boosted performance be ascribed 1D structure with multiple heterostructures abundant defects, which generate conductive loss, diverse polarizations, scattering, cooperative heat transfer of electrons phonons. Further analyses reveal dielectric loss mechanisms based on density states, electric field distribution, phonon states. Overall, promising applications sensing, management, EM protection, Radar stealth, particularly extreme environments.

Abstract Herein, a novel Janus-structured multifunctional membrane with integrated electromagnetic interference (EMI) shielding and personalized thermal management is fabricated using shear-induced in situ fibrillation vacuum-assisted filtration. Interestingly, within the polytetrafluoroethylene (PTFE)-carbon nanotube (CNT)-Fe 3 O 4 layer (FCFe), CNT nanofibers interweave PTFE fibers to form stable “silk-like” structure that effectively captures Fe particles. By incorporating highly conductive MXene layer, FCFe/MXene (FCFe/M) exhibits excellent electrical/thermal conductivity, mechanical properties, flame retardancy. Impressively, benefiting from rational regulation of component proportions design Janus structure, FCFe/M thickness only 84.9 µm delivers outstanding EMI effectiveness 44.56 dB X-band, normalized specific SE reaching 10,421.3 cm 2 g −1 , which attributed “absorption-reflection-reabsorption” mechanism. Furthermore, demonstrates low-voltage-driven Joule heating fast-response photothermal performance. Under stimulation V voltage an optical power density 320 mW −2 surface temperatures membranes can reach up 140.4 145.7 °C, respectively. In brief, anti-electromagnetic radiation temperature attractive candidate for next generation wearable electronics, compatibility, visual heating, thermotherapy, military aerospace applications.

ABSTRACT The increasing proliferation of electronic devices and advanced communication networks has resulted in heightened electromagnetic interference (EMI), posing significant challenges both technological environmental contexts. Traditional EMI shielding materials, such as metals composite coatings, offer limited adaptability are unable to meet the dynamic demands modern systems. Recent advancements have introduced smart stimuli‐responsive materials for shielding, which provide real‐time tunability, thereby addressing limitations conventional static solutions. These leverage various mechanisms—such compressive tensile strains, phase transitions, shape memory effects, responses chemical agents, humidity, or crossover angle changes—to dynamically adjust their effectiveness (EMI‐SE). This review provides an in‐depth analysis recent progress technologies, highlighting tunable mechanisms, material compositions, applications. Furthermore, it discusses existing potential future research directions required advancement this technology. By enabling environments, present a promising solution telecommunications, wearable electronics, aerospace, defense sectors.
