Abstract In this study, a sustainable biomass‐derived structure from Harmal seed peganum (HSP) is used as substrate to facilitate the growth of carbon nanotubes (CNTs) by Ni catalyst. The unique toutia‐like morphology implanted coated with polydopamine (PDA) via an in situ polymerization process. Persian turpentine (PT) chosen novel, green, sustainable, practical, and polarizable medium, selected capable microwave absorbing medium. influence interfacial interaction on performance carefully dissected addition polyvinyl alcohol (PVA). With ultrathin thickness 200 µm, CNT‐implanted sample PDA enhanced PT (HSP/Ni‐CNT/PDA/PT) achieved maximum RL −79.88 dB at 18.22 GHz efficient bandwidth 7.17 GHz. Interestingly architected totally shields ≥95% k‐band frequencies. promoted impedance matching other effective mechanisms HSP/Ni‐CNT/PDA/PVA/PT HSP/Ni‐CNT/PDA/polyethylene (PE) nanocomposites lead highest −92.87 25.39 0.90 mm broadest wide 8.50 1.20 mm, respectively.

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.
