Multifunctional lithium Aluminosilicate/CNT composite for gas filtration and electromagnetic wave absorption

Construction of 1D Heterostructure NiCo@C/ZnO Nanorod with Enhanced Microwave Absorption

“…However, the failure of electronic facilities, human organ damage and other negative effects caused by electromagnetic pollution deserve our attention [4,5]. In order to make better prevention of EMW, EMW-absorbing materials that can attenuate EMW energy and convert incident EMW into heat or otherwise forms of energy have been designed and developed [6,7]. The idealized absorbing material should meet the requirement of wide bandwidth, light weight and thin thickness [8][9][10].…”

The excellent electromagnetic wave absorbing properties of carbon fiber composites: the effect of metal content

“…Combining the different loss mechanisms of the two materials, [30][31][32] in this work, iron/cobalt/carbon (Fe/Co/C) nanocomposite fibers (M-CNFs) with different metal filling ratios were fabricated to investigate the effect of metal content on EM properties. The obtained composites exhibited enhanced microwave absorption performance due to the synergistic effect of magnetic loss and dielectric loss.…”

Marine polysaccharide-based electromagnetic absorbing/shielding materials: design principles, structure, and properties

“…23 As representatives of magnetic and conductive materials, Fe 3 O 4 and CNTs are widely used in the field of EMW absorption by virtue of their extraordinary magnetic loss, dielectric loss, and conductive loss. 155–158 There are a large number of oxygen-containing functional groups (–COOH and –OH) and defects on the surface of the oxidized CNTs, 159 which not only anchor the magnetic Fe 3 O 4 particles tightly on the surface of CNTs and generate multi-interfacial heterostructures that contribute to interfacial polarization, but also produce abundant dipoles that contribute to relaxation loss with Fe 3 O 4 and several defects as polarization centers. 160 The 3D porous conductive network combining the advantages of SA and CNTs, and the effective multi-interface heterostructures constructed between the two types of magnetic particles and the derived carbon skeletons can be obtained by crosslinking Ni 2+ with the SA–Fe 3 O 4 /CNTs hybrid matrix and carbonizing.…”
