“…To show the superiority of GMFs, Table summarizes the microwave absorption performance of the recently reported graphene-based microwave absorption materials ,,− and the GMFs in this work. Compared with most of these absorbers, the GMF5 has low contents of RGO and MWCNT, low cost, and simple synthesis process, as well as strong microwave absorption intensity, and the RL value was −61.29 dB at 10.48 GHz with a thickness of only 2.6 mm.…”

How to effectively regulate the electromagnetic parameters of magnetic composites to achieve better microwave absorption (MA) performances is still a serious challenge. Herein, we constructed nanocomposites composed of magnetic constituents and carbon materials to obtain high-efficiency electromagnetic wave absorbers. Self-assembled, multi-interfacial, and porous RGO/MWCNT/Fe3O4 hybrids (GMFs) were synthesized via in situ one-pot solvothermal method. The growth mechanism of the GMFs would be that the defects on reduced graphene oxide (RGO) provide sites for the crystallization of Fe3O4. Also, the RGO and Fe3O4 were further linked by the cross-connection of multiwalled carbon nanotubes (MWCNTs), which acted as a bridge. The MA mechanism of GMFs was studied while considering the synergistic effects between the three components (RGO, MWCNT, and raspberry-shaped Fe3O4) and their multi-interfacial and porous structure. Also, the MA performance of the GMFs was conducted. The GMFs exhibited a maximum reflection loss (RL) value of −61.29 dB at 10.48 GHz with a thickness of 2.6 mm when the contents of RGO and MWCNT were 6.3 and 1.3 wt %, respectively. The RL values (≤−10 dB) were observed to be in the range of 8.96–12.32 GHz, and the effective microwave absorption bandwidth was tunable from 3.52 to 18 GHz by changing the sample thickness. The results revealed that the multi-interfacial and porous structure of the GMFs is beneficial to MA performance by inducing multiscatterings. Since no toxic solvents were used, this method is environmentally friendly and has potential for large-scale production. The prepared GMFs may have a wide range of applications in MA materials against electromagnetic interference pollution.

“…Base on the transmission line theory complex permeability, complex permittivity, diameter of absorber, and frequency are the most effective factors in microwave properties of materials [7]. Barium hexaferrite as a hard magnetic material has magnetic properties desirable for complex permeability and silicone rubber as a dielectric polymer matrix is desirable for complex permittivity.…”

Recently, barium ferrite nanoparticles have attracted substantial attention because of widespread applications in catalytic degradations, credit cards, storage hardware, sensors, microwave devices, permanent magnets, high frequency devices, photocatalyst, and etc. In this research, templated BaFe 12 O 19 nanoparticles were prepared through the sol-gel method by use of cotton as a template in the sol step. Finally, templated nanoparticles were blended in the silicone rubber matrix and then prepared nanocomposite molded to investigate of microwave absorption properties at x-band frequency. Templated barium hexaferrite nanoparticles were characterized by Fourier transform infrared (FT-IR), diffuse reflection spectroscopy (DRS), vibrating sample magnetometer (VSM), field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and microwave absorption characteristics were obtained by vector network analyzer (VNA). Microwave absorption curves showed that templated BaFe 12 O 19 /silicone rubber nanocomposite absorbed 65.80% of microwaves at 9.87 GHz.
