摘要：
Ti3SiC2 particles encapsulated by Ni0.5Zn0.5Fe2O4 shell were in-situ synthesized via a facile sol-gel method. Effects of Ni(0.5)Zno(5)Fe(2)O(4) shell on electromagnetic properties of Ti3SiC2 were investigated in 2-18 GHz. Moderated complex permittivity and desirable higher complex permeability presented for the Ni0.5Zn0.5Fe2O4/Ti3SiC2 composite, resulting in strong microwave attenuation ability and good impedance matching property. The measured effective absorbing bandwidth (RL < -10 dB) of 5.3 GHz and corresponding maximum RL of -38.6 dB were obtained for the Ni0.5Zn0.5Fe2O4/Ti3SiC2 absorbing coating of 1.2 mm thickness. These results indicate that the Ni0.5Zn0.5Fe2O4/Ti3SiC2 composite may become a new type of microwave absorbent.
