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.

Recent Advances in Stimuli‐Responsive Materials for Electromagnetic Interference Shielding

Polymers for Advanced Technologies, Год журнала: 2025, Номер 36(2)

Опубликована: Фев. 1, 2025

ABSTRACT The increasing proliferation of electronic devices and advanced communication networks has resulted in heightened electromagnetic interference (EMI), posing significant challenges both technological environmental contexts. Traditional EMI shielding materials, such as metals composite coatings, offer limited adaptability are unable to meet the dynamic demands modern systems. Recent advancements have introduced smart stimuli‐responsive materials for shielding, which provide real‐time tunability, thereby addressing limitations conventional static solutions. These leverage various mechanisms—such compressive tensile strains, phase transitions, shape memory effects, responses chemical agents, humidity, or crossover angle changes—to dynamically adjust their effectiveness (EMI‐SE). This review provides an in‐depth analysis recent progress technologies, highlighting tunable mechanisms, material compositions, applications. Furthermore, it discusses existing potential future research directions required advancement this technology. By enabling environments, present a promising solution telecommunications, wearable electronics, aerospace, defense sectors.
