A Pomegranate‐Like Nanolayer Featuring A Core‐Shell Architectural Design for Thermal‐Mechanical‐Electromagnetic Responses and Sensor

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 12, 2024

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.
