To meet the demands for high-performance and cost-effective electromagnetic wave absorbers in practical applications, CoNi alloy/N-doped hollow carbon foam (CoNi/NCF) was synthesized using melamine as a precursor through hydrothermal reaction. By introduction of appropriate alloys to form uniform magnetic metal nanoparticles on surface NCF, absorption performance NCF can be adjusted. These formed rich heterogeneous interfaces with enhancing interface polarization loss composite material waves. The alloy increased conductivity materials, which conducive formation three-dimensional conductive network promoted conduction As metal, also brought losses increasing ways consume Additionally, doping N atoms dipole NCF. minimum reflection (RLmin) CoNi/NCF reached −47.35 dB, maximum effective bandwidth (EAB) 5.6 GHz (2.4 mm). effectively reduced radar cross-section (RCS) signal electric conductor layer. This study provides feasible strategy developing materials an efficient performance.

Abstract Polymer‐derived ceramics (PDCs) are typically prepared as ceramic‐based microwave absorption materials by doping with high‐dielectric or transition metals, which may lead to the issue of uneven mixing. This study achieves uniform blending at molecular level using poly(dimethylsilylene)diacetylenes (PDSDA) modify hyperbranched polyborosilazane (PBSZ). The alkynyl group and Si−H bonds crosslink form a ceramic precursor, is then pyrolyzed prepare SiBCN excellent performance high temperature stability. introduction PDSDA significantly improved yield, resulting in situ formation more ordered carbon, SiC nanocrystals, nanowires within ceramics. These nanophases uniformly dispersed throughout matrix, enhancing ceramic's dielectric loss properties. After 1400°C, derived from precursor PBSZ:PDSDA mass ratio 10:1 exhibits electromagnetic wave properties, minimum reflection −50.11 dB maximum effective bandwidth 3.11 GHz. Moreover, maintain stability 1500°C both argon air environments. fully exploits designability molecules, providing new approach for preparation PDCs route.
