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.
