3D Seed-Germination-Like MXene with In Situ Growing CNTs/Ni Heterojunction for Enhanced Microwave Absorption via Polarization and Magnetization.

ABSTRACT:

Highlights

Benefiting from the possible "seed-germination" effect, the "seeds" Ni²⁺ grow into "buds" Ni nanoparticles and "stem" carbon nanotubes (CNTs) from the enlarged "soil" of MXene skeleton. Compared with the traditional magnetic agglomeration, the MXene-CNTs/Ni hybrids exhibit the highly spatial dispersed magnetic architecture. 3D MXene-CNTs/Ni composites hold excellent microwave absorption performance (-56.4 dB at only 2.4 mm). Ti₃C₂T_x MXene is widely regarded as a potential microwave absorber due to its dielectric multi-layered structure. However, missing magnetic loss capability of pure MXene leads to the unmatched electromagnetic parameters and unsatisfied impedance matching condition. Herein, with the inspiration from dielectr
