Construction of multi-dimensional NiCo/C/CNT/rGO aerogel by MOF derivative for efficient microwave absorption

Construction of 1D Heterogeneous Co/C@Ag Nws With Tunable Electromagnetic Wave Absorption And Shielding Performance

“…[ 22b,25 ] On the other hand, there are abundant functional groups and defects in the Co/C@Ag NWs composites, which are facilitated by the improvement of dipole polarization and defect polarization. [ 18 ]…”

“…The porous structure of composites not only extends the transmission path but also facilitates the multiple reflection and scattering of electromagnetic waves in the internal space owing to the large S BET and V pore . [18] 2.1. 4…”

“…[22b,25] On the other hand, there are abundant functional groups and defects in the Co/C@Ag NWs composites, which are facilitated by the improvement of dipole polarization and defect polarization. [18] Figures 4e,f show the μ′ and μ″ values of four samples vary with frequency. The μ′ values of all four samples can be observed to fluctuate from 0.8 to 1.2 but little difference, indicating a sim-ilar magnetic storage capacity.…”

Three-dimensional biotemplate-loaded nickel sulfide vacancies engineered to promote the absorption of electromagnetic waves

“…[1][2][3][4] These devices are being increasingly used in different frequency bands to address significant issues, such as electromagnetic radiation, pollution, and interference. [5][6][7][8] Electromagnetic wave (EMW) absorption materials can effectively absorb EMWs and convert them into thermal energy or alternative forms of energy. 9,10 Additionally, they can dissipate EMWs through interference, thereby reducing unnecessary electromagnetic radiation.…”

Synthesis of nitrogen-doped graphene aerogels modified by magnetic Fe3O4/Fe/C frameworks as excellent dual-band electromagnetic absorbers

“…8 Recent studies have shown that the surface of RGO is rich in chemical groups, which contribute to the generation of electric dipole relaxation. 9,10 Therefore, RGO has potential application prospects as an EMW absorber. However, the impedance mismatch and single dissipation mechanism of RGO result in an unsatisfactory ability to absorb electromagnetic waves.…”
