Low-Temperature Oxidation Induced Phase Evolution with Gradient Magnetic Heterointerfaces for Superior Electromagnetic Wave Absorption

Nano-Micro Letters, Год журнала: 2024, Номер 17(1)

Опубликована: Сен. 22, 2024

Abstract Gradient magnetic heterointerfaces have injected infinite vitality in optimizing impedance matching, adjusting dielectric/magnetic resonance and promoting electromagnetic (EM) wave absorption, but still exist a significant challenging regulating local phase evolution. Herein, accordion-shaped Co/Co 3 O 4 @N-doped carbon nanosheets (Co/Co @NC) with gradient been fabricated via the cooperative high-temperature carbonization low-temperature oxidation process. The results indicate that surface epitaxial growth of crystal Co domains on nanoparticles realizes adjustment magnetic-heteroatomic components, which are beneficial for matching interfacial polarization. Moreover, simultaneously realize coupling, long-range diffraction. Specifically, synthesized @NC absorbents display strong attenuation capability − 53.5 dB at thickness 3.0 mm an effective absorption bandwidth 5.36 GHz, both superior to those single embedded matrix. This design concept provides us inspiration polarization, coupling absorption.

Abstract The modulation of transport properties in ceramic‐based semiconductors can be used to optimize the electromagnetic response mechanism and performance. A semiconductor ceramic foam interlayer wall (SCFW) is designed by a physical vapor deposition method. structural SCFW composed semiconductor‐insulator‐semiconductor layers, incorporating composite system SiC, Al 4.8 Si 1.2 O 9.6 , 2 3 . Moreover, hierarchical network structure controlled pyrolysis‐deposition kinetic process. Electrons holes are transported through heterojunctions between SiC achieving effective charge relaxation. matrix provides lightweight (density 0.967 g cm −3 ), while determines excellent wave (EMW) absorption performance SCFW, with an bandwidth up 14.8 GHz under (minimum reflection loss RL min = −50.6 dB). has been proven exhibit corrosion resistance thermal insulation properties, conductivity 0.025 W m −1 K This study valuable insights into design dielectric property optimization nanocomposites, which leads strong polarization loss, opening new avenues for application EMW absorbers, ceramics.
