Self-cleaning functionalized FeNi/NiFe2O4/NiO/C nanofibers with enhanced microwave absorption performance

Microwave Absorption Properties of Magnetite Particles Extracted from Nickel Slag

“…Microwave energy dissipates when an EM wave interacts with an MAM, which then converts this energy into another one (e.g., thermal) through its own electric and magnetic losses. However, achieving best performance for material containing only a single component is difficult because of impedance mismatch [5,6].…”

Lightweight electromagnetic wave absorbent composites with Fe3O4 nanocrystals uniformly decorated on the surface of carbon spheres

“…Compared with carbon-based microwave absorbent materials from previous work (as shown in Fig. 6), 44–49 the carbon sphere/Fe 3 O 4 (CS/Fe 3 O 4 ) composite electromagnetic wave absorbent material samples exhibited excellent electromagnetic wave absorption performance at relatively small thicknesses and have great potential for application.…”

“…However, the high dielectric constants of single dielectric loss materials often lead to impedance mismatches, limiting their development as electromagnetic wave absorbent materials. Magnetic loss materials, such as Fe, Ni, Co, and their oxides [23][24][25][26][27][28][29] have good electromagnetic wave loss capability due to their magnetic properties. However, the high density and specific gravity of magnetic loss materials make it difficult to meet the development aim of lightweight electromagnetic wave absorbent materials.…”

NiCo@NPC@CF nanocomposites derived from NiCo-MOF/cotton for high-performance electromagnetic wave absorption

“…9. 47 Firstly, the enhanced conductivity of the 3D carbon interconnected network derived from biomass cotton could accelerate the complex permittivity, electron transportation and dielectric loss, thereby giving incomparable impedance matching. [48][49][50] Secondly, the multiple interfaces between the NiCo alloy, CNTs, CFs and paraffins can facilitate the interface polarization.…”
