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 Ti3C2Tx/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 Ti3C2Tx/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 Ti3C2Tx/Fe3O4 composites with bud-like structure exhibit superior microwave absorbing properties which demonstrate a promising application in electromagnetic interference shielding field.
