Ni-modified Ti3C2 MXene with enhanced microwave absorbing ability

Abstract

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.
