“…Therefore, MXene‐based composite was very thin and exert excellent EMI shielding similar to metallic shielding materials (Figure (d)). In addition, fabricated composite fabric gave rise to good shielding compared with graphene, multiwall carbon nanotube, and other carbon base composites . Hence, nonwoven carbon fabric was an excellent choice over cellulose nanofiber/MXene composite (Cao et al .…”

MXene and nonwoven carbon fabric are good candidate for flexible, light‐weight electromagnetic interference (EMI) shielding fabric. The prepared composite was characterized using X‐ray diffraction, X‐ray photo electron spectroscopy, energy‐dispersive X‐ray spectroscopy, scanning electron microscope, mapping, and Raman spectroscopy. The 15 times coated composite displayed a contact angle of 123°, a wetting energy of −39.86 mN/m, a spreading coefficient of −112.66 mN/m, and 32.94 mN/m work of adhesion. The fabricated composites inhibited thermal degradation until 235 °C. The composite revealed an excellent electric conductivity of 8.5 S/cm with a sheet resistance of 6.5 Ω/sq. The composite showed a maximum EMI shielding of 43.2 dB at 2.3 GHz with 8534.7 dB cm2/g. The composite displays better outlook application areas such as aviation, portable electronics, radars, aerospace, and military.

In this research (PANI/CNT) core/shell nanocomposite were synthesized via in situ chemical oxidative seeding polymerization‚ the results of SEM indicated the structure of synthesized nanocomposite. TEM‚ FTIR‚ UV-Vis‚ XRD analyses of samples showed that this nanocomposite is decorated with (Fe‚ Co) oxide nanoparticles. The VSM test of as prepared and annealed nanocomposite exhibited the saturated magnetization of 1.1 and 3.86 emu/g, respectively; the coercivity values were also − 350 and − 110 Oe, respectively. The reflection loss characteristics of (Fe‚ Co) oxide-Pani-CNT core/shell nanocomposite were also investigated with a vector network analyzer‚ in the 8.2-12.4 GHz range (X band). The maximum absorption increases with enhancement of the dispersed nanoparticles percent in polyurethane matrix from 1 to 10%. The value of the maximum reflection loss in the absorption samples with 1 and 10% of nanoparticles is − 2.14 dB at 9.33 GHz and − 7.32 dB at 11.97 GHZ, respectively.

“…As the development of new types of EM absorbers only by varying magnetic components and permeability is quite limited, much research attention has been directed towards finding innovative dielectric loss materials with low density and high loss performance. Among various kinds of dielectric loss materials, carbon materials have always been attractive due to their low density, abundant resources, and low cost [27][28][29]. In particular, carbon nanotubes have been regarded as one competitive candidate based on their good conductivity, strong mechanical property, and high aspect ratio.…”

The composite structure of Co beads (200-300 nm) threaded by carbon nanotubes has been synthesized through a facile solvothermal method followed by a carbon reduction process. A carbon layer of ca. 5 nm was coated on the surface of Co beads to form a coreshell structure (CNTs/Co@C), in favor of the antioxidation of Co nanoparticles. The CNTs/Co@C hybrid showed a saturation magnetization (M s ) of 82.5 emu g −1 and a larger H c value of 258.8 Oe than bulk Co (ca. 10 Oe). Served as an EM wave absorption material, the epoxy resin composites consisting of 60 wt% and 40 wt% CNTs/Co@C hybrid exhibited effective EM absorption (RL < − 10 dB) over the frequency ranges of 1.5-15 and 1.6-20 GHz with the matching thicknesses of 1.0-7.5 and 1.0-10.0 mm, respectively. The superior EM absorption performances of CNTs/Co@C hybrid containing strong absorption, wide frequency range, thin thickness, and light weight are mainly attributed to the synergy of magnetic loss from Co beads and dielectric loss from carbon nanotubes, as well as remarkable impedance matching.
