Enhanced microwave absorption properties of Ti3C2 MXene powders decorated with Ni particles

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.
