In this work, we have demonstrated the enhancement of the microwave absorbing capability of Ni-modified MXene within a frequency range of 2–18 GHz. The Ni-modification makes MXene able to attenuate microwave energy through magnetic loss as well as a strong dielectric loss. The effective absorbing bandwidth is greatly broadened, especially at the lower frequency of 2–8 GHz. The synergistic effect of dielectric loss and magnetic loss and the structure effect are believed to be the main reasons behind the broadening of the effective microwave absorbing bandwidth.

具有增强的微波吸收能力的 镍改性的Ti ₃ C ₂ MXene

在这项工作中，我们证明了Ni改性MXene在2–18 GHz频率范围内的微波吸收能力的增强。Ni改性使MXene能够通过磁损耗和强介电损耗来衰减微波能量。有效吸收带宽大大拓宽了，尤其是在2-8 GHz的较低频率下。介电损耗和磁损耗的协同效应以及结构效应被认为是有效微波吸收带宽变宽的主要原因。
