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.

Although materials with infrared camouflage capabilities are increasingly being produced, few applications exist in clothing fabrics. Here, graphene/MXene-modified fabric superior camouflage, Joule heating, and electromagnetic shielding all one was prepared by simply scraping a graphene slurry onto alkali-treated cotton fabrics, followed spraying MXene. The functionality of the modified fabrics after different treatment times then tested analyzed. results indicate that mid-infrared emissivity decreases an increase coating When at loads 5 1.2 mg/cm2, respectively, have very low 3–5 8–14 μm bands, surface temperature can be reduced 53.1 °C when placed on heater 100 (surface radiation 95 °C). also demonstrates excellent heating capabilities; 4 V power, 91.7 may reached 30 s. In addition, customized exhibit strong performance. By folding cloth, interference shield effect increased to 64.3 dB. With their thermal management, performance, found extensive use intelligent wearables military applications.

Miniaturized and wearable electronic products require electromagnetic interference shielding (EMI) materials with sensing functions to cope complex application situations. Herein, an effective dual-network structure is designed fabricate two-dimensional transition metal carbides nitrides/bacterial cellulose-thermoplastic polyurethane (MXene/BC-TPU) foams intriguing EMI property piezoelectric ability under both compressive tensile strains. Anisotropic MXene/BC aerogels, as conductive networks, impressive conductivity (1912 S m-1), ultrahigh effectiveness (SE) of 86 dB, absolute SE up 63,608 dB cm2 g-1 can be built by directional freezing. Interpenetrated neuro-like TPU network embedded into the aerogels controllable coagulation provide elasticity. Inheriting elastic network, light weight MXene/BC-TPU show superb elasticity remarkable fatigue resistance suffering strains a wide strain range (-80-80%). Meanwhile, benefiting from separated display outstanding (76 dB) retention 86.8% after 5000 compression-release cycles 69.7% 100 stretch-release cycles, respectively. Furthermore, reveal stable signal output piezoresistive sensors in -80-80%. The highly conductive, stretchable, compressible are suitable motion monitoring for electronics.
