“…Drop by drop, aqueous organic solvent was then incorporated into the reaction mix to get the pH level to 9.0. To create a uniform solution, the process was continually agitated for 3 h. Last but not least, the material was calcined for 3 h at 500 °C to produce a fine powder of zinc oxide nanoparticles [ 11 ].…”

“…Polythiophene (PT) and its derivatives are very promising conducting polymers due to their numerous remarkable properties such as environmental and thermal stability [1][2][3], high electrical conductivity [4][5][6] and interesting electronic and optical characteristics [7][8][9][10]. Thanks to these features, polythiophene offers several industrial applications in various fields, including electronic devices such as transistors [11][12][13], organic light-emitting diodes (OLEDs) [14,15], photovoltaic cells [16][17][18][19], electrochromic devices [20,21] and sensors [22][23][24].…”

Electropolymerization of thiophene was performed in aqueous acidic media on various substrates, namely, titanium, nickel and SS steel. The films were successfully elaborated using voltamperometric, chronopotentiometric and chronoamperometric techniques. It was shown that concentrated acids increase the solubility of the monomer, lower its oxidation potential and inhibit the dissolution of the working electrode. Furthermore, the electrosynthesized polythiophene (PT) films are homogeneous and present similar properties to those obtained in organic media. On the other hand, analyses by X-ray photoelectron and infrared spectroscopies indicate the higher oxidation state of the polymers and the contribution of the supporting electrolyte in the doping process. In addition, IR spectra have demonstrated the strictly a, a’ linked polythiophene chains and an estimated degree of polymerization (DP) of about 40. Finally, scanning electron microscopy (SEM) has been used to characterize the morphology of the obtained coating. In this context, the nature of the films depends closely on the type of the electrode, the electrosynthesized mode and the electrolytic medium.

“…[4] EMI not only harms telecommunication and technological devices, but it also has negative health consequences. [5][6][7][8][9] EMI causes wireless communication devices to fail; therefore, it is critical to design EMI shielding/absorbing materials suitable over a broad frequency range. [10,11] Therefore, several attempts have been made to eliminate undesired electromagnetic (EM) waves throughout a broad frequency range, as they are detrimental to human health and technological equipment.…”

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.
