Novel multilayer-like structure of Ti3C2Tx/CNZF composites for low-frequency electromagnetic absorption

Here, a novel hierarchical composite of Co 0.2 Ni 0.4 Zn 0.4 Fe 2 O 4 nanoparticles (CNZF) decorated on MXenes (Ti 3 C 2 T x /CNZF) was fabricated by a moderate hydrothermal reaction. Thanks to the CNZF nanoparticles that are favorable to the delamination of hierarchical structure, the dielectric lo...

Description
Summary:Here, a novel hierarchical composite of Co 0.2 Ni 0.4 Zn 0.4 Fe 2 O 4 nanoparticles (CNZF) decorated on MXenes (Ti 3 C 2 T x /CNZF) was fabricated by a moderate hydrothermal reaction. Thanks to the CNZF nanoparticles that are favorable to the delamination of hierarchical structure, the dielectric loss and multiple scattering of Ti 3 C 2 T x /CNZF are greatly enhanced. Accordingly, the composite exhibited a remarkable microwave absorption, with a maximum reflectivity of −58.4 dB at 6.2 GHz. Likewise, the efficient bandwidth is at lower frequency region of 3.8–6.0 GHz as thickness was 4.2 mm. The present method provide a strategy to design novel 2D absorbers by allowing ultrasmall magnetic particles to deposit at the hierarchical structure.
