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.

Abstract The pressing demand for ultrathin and flexible shields to counter electromagnetic interference (EMI) has sparked interest in Ti 3 C 2 T x MXene materials due their exceptional electrical conductivity, tunable surface chemistry, layered structure. However, pure films often lack the mechanical properties required practical engineering applications, traditional reinforcement methods tend reduce conductivity. This work demonstrates an effective strategy enhance alignment densely packed structure of by regulating acidity alkalinity aqueous solutions. approach simultaneously improves strength shielding effectiveness (EMI SE). Compared with original films, modified ammonia solution (NH ·H O) via OH − show a significant improvement tensile (27.7 ± 1.9 MPa). Meanwhile, treated hydrochloric acid (HCl) H + reach even higher 39 1.5 MPa. Moreover, EMI SE values increase significantly, each reaching 66.2 58.4 dB. maximum improvements acid- alkali-treated samples are 17.9% 4%, respectively. In conclusion, simultaneous enhancement efficacy highlights potential applications materials. Graphical abstract
