Quadrangular cone carbon-constructed effective 3D network for a lightweight and broadband microwave absorbent

Abstract

Quadrangular cone carbon-constructed 3D network shows an excellent broadband performance of 6.7 GHz at an ultra-low filler loading of only 1.04 wt%.

Dendrimer-assisted defect and morphology regulation for improving optical, hyperthermia, and microwave-absorbing features

“…A constructive trade-off between the α and Z leads to an acceptable RL and efficient bandwidth. 76,77 This factor is adjusted by the magnetic and dielectric potentials of the samples. Evidently, Ca/Fe 3 O 4 , CaFe 2 O 4 , and D-A hydrothermal CaFe 2 O 4 exhibited the excess microwave dissipation, generated from the magnetic resonances, boosted polarization types, and conductive loss, modulated by the morphology and phase.…”
