Abstract In the field of electromagnetic interference shielding, ferrite is a commonly used coated microwave absorber, but there are some shortcomings in Fe₃O₄, the leading of ferrite. Herein bud-like Ti₃C₂T_x/Fe₃O₄ composites were successfully prepared by freeze-drying. The multiple reflections of electromagnetic waves caused by bud-like structure, interface polarization and electromagnetic coupling result in a high microwave absorption performance of the Ti₃C₂T_x/Fe₃O₄ composite. When the frequency is 6.74 GHz, the minimum reflection loss is -51.41 dB with the corresponding matching thickness of 2.8 mm, which indicates that it has 99.999 28% absorption of electromagnetic wave. The Ti₃C₂T_x/Fe₃O₄ composites with bud-like structure exhibit superior microwave absorbing properties which demonstrate a promising application in electromagnetic interference shielding field.

Key words： MXene Ti₃C₂T_x/Fe₃O₄ composites wave absorption electromagnetic interference (EMI) shielding microwave absorber
