Synchronously boosting microwave-absorbing and heat-conducting capabilities in CeO₂/Ce(OH)₃ core–shell nanorods/nanofibers via Fe-doping amount control

Abstract

To address the electromagnetic interference (EMI) and heat dissipation issues in electronics, we pioneered the synthesis of Fe-doped CeO2/Ce(OH)3 core-shell nanorods/nanofibers (CSNRs/NFs) through a simple one-pot hydrothermal reaction. The growth...

Synchronous achievement of ultra-wideband microwave absorption and high thermal conduction in spongy TiO2-based magnetic composites via constructing magnetic/dielectric double loss and phonon/electron co-transmission

“…11b). 2,11–20,65–70 Moreover, the loading amount of 30% is lower than those of most other fillers (45–100%). 2,11–20,69…”

Graphene/silver nanowire aerogel sponge for highly effective electromagnetic energy attenuation

“…Fluctuations in the dielectric constant may arise from polarization relaxation. 34,35 The diverse relaxation process is conducive to a strong RL absorption peak, high conductive loss, and excellent impedance matching, which are caused by a broad effective absorption frequency. 36…”

Constructing magnetic/dielectric dual loss and phonon/electron thermal carriers γ-Al2O3-based yolk–shell microspheres to collaboratively advance microwave absorption and heat conduction

“…A large surface/interface area can boost interfacial polarization for EMW absorption but reduce heat conductance due to the enhanced phonon-boundary scattering. Generally, the collaborative enhancement of thermal and EMW absorptive properties can be realized through composition modulation, morphology/size design, 19 defect/interface regulation, 20 and the establishment of 3D electron/phonon pathways. 21,22 With these methods adopted, some bifunctional materials have been synthesized with synergistically enhanced heat conduction and EMW absorption.…”
