Electromagnetic (EM) wave absorbing materials play an increasingly important role in modern society for their multi-functional military stealth and incoming 5G smart era. Dielectric loss EM absorbers underlying mechanism investigation are of great significance to unveil attenuation behaviors guide novel dielectric design. However, current researches focus more on synthesis rather than in-depth study. Herein, comprehensive views toward mechanisms including interfacial polarization, dipolar conductive loss, defect-induced polarization provided. Particularly, some misunderstandings ambiguous concepts each highlighted. Besides, study emphasized. Moreover, new regulation strategies instead regular components compositing summarized provide inspiring thoughts simple effective behavior modulation.

Abstract High‐frequency electromagnetic waves and electronic products can bring great convenience to people's life, but lead a series of interference (EMI) problems, such as potential dangers the normal operation components human safety. Therefore, research EMI shielding materials has attracted extensive attention by scholars. Among them, polymer‐based with light weight, high specific strength, stable properties have become current mainstream. The construction 3D conductive networks proved be an effective method for preparation excellent effectiveness (SE). In this paper, mechanism is briefly introduced, emphasis on methods latest progress different networks. key scientific technical problems solved in field are also put forward. Finally, development trend application prospects prospected.

Abstract Lightweight, ultra-flexible, and robust crosslinked transition metal carbide (Ti 3 C 2 MXene) coated polyimide (PI) (C-MXene@PI) porous composites are manufactured via a scalable dip-coating followed by chemical crosslinking approach. In addition to the hydrophobicity, anti-oxidation extreme-temperature stability, efficient utilization of intrinsic conductivity MXene, interfacial polarization between MXene PI, micrometer-sized pores composite foams achieved. Consequently, show satisfactory X-band electromagnetic interference (EMI) shielding effectiveness 22.5 62.5 dB at density 28.7 48.7 mg cm −3 , leading an excellent surface-specific SE 21,317 g −1 . Moreover, exhibit electrothermal performance as flexible heaters in terms prominent, rapid reproducible, stable effect low voltages superior heat more uniform distribution compared with commercial composed alloy plates. Furthermore, well attached on human body check their electromechanical sensing performance, demonstrating sensitive reliable detection motions wearable sensors. The EMI multifunctionalities, along facile easy-to-scalable manufacturing techniques, imply promising perspectives C-MXene@PI next-generation electronics, aerospace, smart devices.

The construction of structures with multiple interfaces and dielectric/magnetic heterostructures enables the design materials unique physical chemical properties, which has aroused intensive interest in scientific technological fields. Especially, for electromagnetic (EM) wave absorption, enhanced interface polarization improved impedence match high Snoek's limitation could be achieved by heterostructures, respectively, are benificial to high-efficiency absorption (EWA). However, far, principles or relationships between those their EWA performance have not been fully summarized reviewed. This article aims provide a timely review on research progresses high-efficency EM absorbers focusing various promising materials. Particularly, attenuation mechanisms discussed generalized. Furthermore, changllenges future developments based proposed.
