摘要：
Double loss absorbers have attracted considerable attention due to their lightweight, thin thickness and excellent absorption performance. Herein, double loss Ti3C2/Ni absorbent was fabricated by decorating Ti3C2 MXene powders with magnetic Ni particles. Electromagnetic and microwave absorption properties of the Ti3C2/Ni absorbent were investigated in the frequency range of 8.2-12.4 GHz. Combining magnetic Ni particles tailored not only the electromagnetic parameters but also the microwave absorption property. The sample with Ti3C2/Ni powders exhibited favorable absorption performance. For the mixture with a thickness of 2.2 mm, a frequency band range of below - 10 dB reached over 8.66-11.26 GHz, with a minimum reflection loss value of - 24.3 dB at 9.8 GHz. Therefore, novel Ti3C2/Ni powders are expected to be a promising absorbent for thin and lightweight microwave-absorbing materials.
