Asymmetric Structural Design for Absorption‐Dominated Electromagnetic Interference Shielding Composites

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 28, 2025

Abstract Excessive electromagnetic pollution caused by waves can interfere with the normal use of electronic devices or cause unnecessary damage to human health. Although conductive polymer composites (CPCs) are used replace traditional metals as an effective strategy for managing undesirable waves, CPCs have a non‐negligible trade‐off in enhancement interference (EMI) shielding effectiveness and absorption coefficient because their reflection‐dominated EMI mechanism. Therefore, alleviate secondary pollution, absorption‐dominated asymmetric structures urgently needed. Recently, structural designs advanced significantly, but seldom been summarized discussed detail. Consequently, this review first systematically summarizes current progress after brief clarification about necessity configuration structure design. Afterward, various fiber, layered, porous, composite described. Besides, versatility is briefly introduced. Finally, challenges prospects proposed guide future advancement field.

3D Porous Graphene with Atomic Fe Coordinated by Pyrrole‐N Dopants for Efficient Electromagnetic Wave Absorption with Low Filler Loading and Thin Thickness

Small, Journal Year: 2025, Volume and Issue: unknown

Published: April 30, 2025

Abstract Achieving effective electromagnetic wave (EMW) absorption performance with less than 2 mm remains a significant challenge in developing EMW materials. Herein, Fe atoms embedded into NH 3 ‐treated 3D porous graphene (3DPG‐NH ‐Fe) are synthesized via simple method of ion impregnation for efficient absorption. The process enables the formation specific pyrrole‐N dopants 3DPG, which provide anchoring sites complexing to construct FeN x moieties. Compared pristine 3DPG‐NH ‐Fe exhibits remarkable characteristics, achieving minimum reflection loss (RL) −56.35 dB and an bandwidth (EAB) 4.45 GHz at low filler loading wt.% thin thickness 1.4 mm, exceeding most reported graphene‐based outstanding is critically attributed incorporation coordinated by strong orbital hybridization N‐p y Fe‐3d x2‐y2 graphene, not only produces additional dipoles but also generates high spin atomic magnetic moment, thus enhancing both dielectric EMW.
