Incorporation of magnetic loss component is more favorable to high-performance microwave absorbing materials. In this paper, the NiFe2O4-decorated Ti3C2Tx MXene composites were synthesized by the in-situ chemical co-precipitation method. The magnetic NiFe2O4 nanoparticles were attached on the surfaces or inserted into the interlayers of Ti3C2Tx MXene. Interestingly, we reduced effectively complex permittivity and enhanced magnetic loss by increasing the NiFe(2)O(4 )content on Ti3C2Tx MXene. Stronger electromagnetic attenuation ability and preferable impedance matching property were achieved and considered to be responsible mainly for improving absorbing peaks as well as bandwidth of the NiFe2O4-Ti(3)C(2)T(x )MXene composite. In particular, the NiFe2O4-Ti3C2Tx-20 sample exhibited an optimal effective absorption bandwidth (RL < -10 dB) of 7.68 GHz with the material thickness of only 1.5 mm. These findings are believed to pave the way of further promoting microwave absorption performance of Ti3C2Tx MXene from magnetic functionalized decoration of view.
