“…Metal powders, metallic oxides, ferrites, and other magnetic materials have all been extensively studied in MA applications. Metallic oxides such as Fe 3 O 4 , Co 3 O 4, and CoFe 2 O 4 have greater complex permittivity and complex permeability features than other materials, resulting in better IMPM characteristics [ [11] , [12] , [13] ].…”

“…On the other hand, the structure of composites are favorable to enhance the stability of absorbers [ 21 , 22 , 23 , 24 ]. Reduced graphene oxide (RGO) has great utility in the field of electromagnetic wave absorption due to its residual defects and functional groups [ 25 ].…”

In order to satisfy the requirements of wide frequency bands, the lightweight and strong absorption for the electromagnetic wave absorbing materials, a uniform mixture of FeAl2O4 with RGO/Cu (reduction graphene oxide, RGO) was obtained by the mechanical mixing method, and composite coating was obtained by plasma spraying. The addition of RGO/Cu into FeAl2O4 is conducive to improve the dielectric properties and the impedance matching performance of spinel. When the RGO/Cu composite powders are doped by 10 wt.%, the reflection loss at 15 GHz is −16 dB and the absorption bandwidth is 2 GHz, indicating that the composite material has potential application value in the field of high-frequency wave absorption. The research on the electromagnetic wave absorption mechanism shows that its superior wave absorption performance is determined by the synergistic effect of multiple loss mechanisms such as interfacial polarization, dipole relaxation, natural resonance, exchange resonance, and eddy current loss.

“…In addition, magnetite compositions can be used for electromagnetic (EM) wave absorption, to prevent some human serious diseases such as leukemia and brain tumor; and also, EM interference in precise equipment. 30 With all the mentioned factors in mind, the present research work develops a novel natural laminate, composed of natural Luffa fibers, chitosan, and magnetite nanoparticles. In other words, although in some previous published works, Luffa fibers and chitosan resin have been investigated separately; in the present article, the composite structure of Luffa fibers and chitosan resin is introduced as a natural composite; and the nanocomposite of Luffa fiberschitosan resin-magnetite nanoparticles is introduced as a natural nanocomposite.…”

This article introduces natural composite and nanocomposite panels of Luffa fibers–chitosan resin; and they are subjected to quasi-static penetration tests and compression experiments to discuss their penetration resistance and compression strength. Natural fibers of Luffa cylindrical sponge were used as the reinforcement and natural chitosan resin was produced from shrimp shells. Specimens with various characteristics were produced through hand layup method and they were subjected to penetration test of a blunt-nose punch. Results demonstrated that there is an optimum mass fraction for chitosan and magnetite nanoparticles to achieve the highest penetration strength; and the best layer configuration is as 0 and 90°, alternately. Furthermore, some glass-chitosan composite panels were produced and comparison of their penetration tests and the corresponding Luffa-chitosan composite experiments demonstrated that in a certain condition, the maximum loads of penetrating the punch into the both composite panels are the same. In second type experiments, quasi–static compression tests were performed on some cubic Luffa–chitosan specimens and results showed that the natural composite cube has significant specific absorbed energy; and by selecting its suitable dimensions, a natural energy absorber can be achieved. Development of the natural Luffa–chitosan composite is suggested, based on sustainability considerations; and using it in the bulletproof vests and armors is presented as a creative idea; due to its natural structure, compatibility with human skin, acceptable resistance against the penetration, its biodegradable ability and simple and low cost production process.
