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.

An Electric‐Magnetic Dual‐Gradient Composite Film Comprising MXene, Hollow Fe₃O₄, and Bacterial Cellulose for High‐Performance EMI Shielding and Infrared Camouflage

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

Published: Jan. 15, 2025

Abstract It is crucial to develop electromagnetic interference (EMI) shielding materials with high efficiency (SE) and reduced reflection mitigate the secondary pollution caused by waves (EMWs). Herein, a novel multilayer assembly strategy inspired structure of “Turkish dessert—Baklava” proposed introduce magnetic hollow Fe 3 O 4 nanospheres (HFO) conductive MXene nanosheets into bacterial cellulose (BC) network. Through layer‐by‐layer vacuum filtration approach, composite BC/MXene/HFO film controllable electric‐magnetic dual‐gradient achieved. The construction dual gradients alleviates impedance mismatch at air‐film interface, resulting in reflectivity toward EMWs, while unique HFO facilitates “absorption–reflection–reabsorption” process EMWs. Consequently, as‐prepared (0.35 mm thickness) exhibits an extraordinary EMI SE 67.6 dB as low 5.1 dB. Furthermore, it also demonstrates exceptional mechanical properties, efficient thermal management, Joule heating capabilities, well remarkable passive active infrared camouflage performances. This study offers innovative approach achieve less more absorption expands application scope precision electronics, aerospace, military equipment fields.
