“…Absorbing properties of the medium of ferrite-polymer composites were investigated and the possibilities of improvement of the indicators of reflection of electromagnetic fields in a frequency band of 8...20 GHz were shown in [6]. The studies have shown that the conventional ferrite-polymer composites do not provide (because of low levels of their conductivity) required levels of absorption parameters sufficient for the task set in this work.…”

“…An overview of publications [1][2][3][4][5][6][7][8][9][10][11][12] revealed two main unresolved parts of the problem of absorbing screening the premises equipped with electronic hardware from interference of electromagnetic fields. First of all, there is a need for a scientific substantiation of expediency of synthesis of dispersible ferrite broadband fillers with electrical conductivity exceeding that of known fillers by several orders of magnitude.…”

“…Due to the composites' high attenuation of electromagnetic waves may be employed as antiradar devices and shielding materials to reduce electromagnetic interference. [183] Numerous researchers have synthesized nanocomposites materials capable of absorbing EM radiation, including ferrite/polymer, [184][185][186][187][188][189][190][191][192][193][194] graphene/polymer, [195][196][197][198][199][200][201][202] hexaferrite/polymer, [203][204][205] polyaniline/carbon nanotube, [206][207][208][209][279][280][281][282] and polyaniline/MWCNT nanocomposite. In situ polymerization of MWCNTs/BaM/PANI was used by Afghahi et al [210] Their process begins with 30 min of mixing 10 cm 3 DBSA with water.…”

With the fast growth of wireless communication technology in high‐frequency ranges, electromagnetic (EM) interference has become a growing concern that has drawn international attention. The development of materials that can absorb EM radiation is a crucial solution. This review provides a detailed overview of ferrites, specifically hexagonal ferrites and their composites for microwave (MW) absorption. It examines hexagonal ferrite classifications based on the stacking order of their fundamental blocks and their synthesis methods and strategies for improving their magnetic properties. On the other hand, this review included a detailed examination of hexagonal ferrites–conducting polymer, hexagonal ferrites–2D materials, and hexagonal ferrite–other nanomaterials composites for MW absorption applications. Enhancing MW absorption in hexagonal ferrites‐based microwave absorption materials (MAMs) regulates their EM characteristics, improves impedance matching, and creates a diversity of loss mechanisms. In addition, the limitations, challenges, and opportunities of hexagonal ferrites‐based MAMs are discussed, which will be helpful to those working in related areas. As a general application potential, it is worth mentioning that, as a result of recent promising findings in the synthesis of hexagonal ferrites‐based composites, hexaferrite‐based composites are suitable devices in the area of microwave absorption.

Nanocomposite materials were obtained by synthesizing Ba2Bi2Co2Fe12O22 Nano Particles with polyaniline and polyacrylonitrile polymers. Composites in this nanostructure; structural, magnetic and electromagnetic absorption properties were examined. It was observed from the x-ray analysis that the nano-structured particles had crystalline structure and shown Y-type hexagonal structure. It can be also seen from the IR measurements that it has this structure at 878 and 650 cm −1 . The Electron Spin Resonance experiment of nanoparticles have been measured at room temperature and shown quite wide spectra and splitting factor. Vibration Sample Magnetometer measurements were made at 10-50 and room temperature. It can be said that nanoparticles useable so successful the magnetic recording media, applications of microwave technologies. Electromagnetic absorption experiments were measured approximately 5-20 GHz in the frequency band by used the free space method. These electromagnetic absorbers are using for 1,5 mm. thickness of the samples obtained 6 GHz. wide -50 db. loss of reflection was measured.
