“…Moreover, the bandwidth less than −10 dB (90% of EM absorption) was around 4 GHz (from 9.6 to 13.6 GHz) [87]. Other examples of ICP/carbon hybrid materials with MA properties are summarized in Table 2 and can also be found in a recent review published by Lin et al [7]. The symbols ICP@filler indicates that ICP was synthesized in the presence of the carbon filler.…”

“…Electromagnetic interference (EMI) is a kind of environmental pollution caused by natural phenomena (such as solar flares, electrostatic discharge, etc.) and by electronic devices [1][2][3][4][5][6][7][8][9]. The widespread use of smart electronic and communication equipment has increased the emission of electromagnetic radiation in a wide range of frequency, depending on the technology involved in their fabrication.…”

“…Thus, there is a growing concern about the development of materials able to shield from this radiation. The electromagnetic interference shielding efficiency (EMI SE) of a material is based on its ability of attenuating incident radiation through reflection and absorption mechanism [5][6][7][8]. The first phenomenon is promoted by the presence of mobile charge carriers that interact with the EM waves and is important for electrically conducting materials.…”

The development of sophisticated telecommunication equipment and other electro-electronic devices resulted in a kind of electromagnetic pollution that affects the performance of other equipment as well as the health of human beings. Intrinsically conducting polymers (ICP), mainly polyaniline and polypyrrole, have been considered as promising candidates for applications in efficient electromagnetic interference shielding (EMI) due to their ease of preparation, light weight, good conductivity and corrosion resistance. One of the important advantages of these materials is the capability to interact with the EM radiation through both absorption and reflection mechanisms thus enlarging the field of application. In this context, this review article describes a recent overview of the existing methods to produce intrinsically conducting polymers and their blends for electromagnetic shielding application. Additionally, it highlights the relationship between preparation methods reported in the literature with the structure and properties, such as electrical conductivity, electromagnetic shielding effectiveness (EMI SE), complex permittivity and permeability of these materials. Furthermore, a brief theory related to the electromagnetic mechanism and techniques for measuring the microwave absorbing properties are also discussed.

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