Abstract Multifunctional electromagnetic wave (EMW) absorbing materials are attracting attention because of their potential applications in medical, livelihood, and military. In this study, a pomegranate‐like nanolayer featuring core‐shell architecture (PNCS) is prepared using confinement strategy. Introducing metal atoms into unique design (M‐PNCS, M = Mn, Fe, Co, Ni, Cu) effectively tuned the response improved functions. The Mn‐PNCS composite exhibited highest absorption. Its reflection loss ( RL ) reached −62.39 dB with an effective absorption bandwidth (EAB) at 1.8 mm 6.0 GHz. As charge transport capacity increases, its can be transformed shielding, green shielding index up to 3.54. On basis, used fabricate multifunctional film new strain sensor. This integrated absorption, thermal insulation, hydrophobicity, flexibility, sensing, thus showing for use wearable protective clothing. addition, sensors simulation achieved sensing through coupling effect between patterns. These findings demonstrate that excellent material technical fields EMW devices.

In response to the increasing need for high‐performance microwave absorption materials (MAMs), this study introduces a multiaxis electrospinning method synthesizing graphene‐based aerogel microspheres (GAMs) aimed at broadband (MA). The micro/nanostructures and shell configurations of GAMs are effectively regulated controlled establish predictable structure‐properties relationship via establishing equivalent electromagnetic (EM) models. computational simulations results structure–property employed as guidance evaluate effects structural features, like hollow structures multilayered shells. analysis reveals that enhancing cavity optimizes impedance matching promotes MA performance. Utilizing these insights, fabricated (HGAMs) achieve an effective bandwidth (EAB) 8.1 GHz optimal reflection loss −34.8 dB 3.3 mm thickness. Further involving various hierarchical arranged into mono/bilayer arrays investigate group coupling on performance through synergistically absorptive, interferential, resonant attenuation mechanisms. Actual examination using arch HGAM bilayer confirms simulations, achieving EAB 15 thickness 7 mm. Consequently, approach demonstrates promising avenue developing lightweight, nanostructured MAMs suitable advanced applications.
