Synthesis, Characterization, and Electromagnetic Properties of Ba1.8Sr0.2Co2Fe11.9Pr0.1O22/Ti3C2Tx‐MXene Composites

Ba 1.8 Sr 0.2 Co 2 Fe 11.9 Pr 0.1 O 22 /Ti 3 C 2 T x ‐MXene composites are synthesized with the unique combination of magnetic and conducting components that enhance electromagnetic wave absorption. Ba 1.8 Sr 0.2 Co 2 Fe 11.9 Pr 0.1 O 22 , Ti 3 C 2 T x ‐MXene and their composites in a weight ratio of 100:0 (YM1), 75:25 (YM2) and 50:50 (YM3) are synthesized by sol–gel autocombustion, etching process, and mechanical blending, respectively. From the morphology of the composites, Ba 1.8 Sr 0.2 Co 2 Fe 11.9 Pr 0.1 O 22 particles are confirmed to be well‐integrated with the Ti 3 C 2 T x ‐MXene, indicating that the Ba 1.8 Sr 0.2 Co 2 Fe 11.9 Pr 0.1 O 22 particles are evenly distributed in the Ti 3 C 2 T x ‐MXene, leading to homogeneous composites. M – H loop exhibits a saturation magnetization and coercivity of 23.01 emu g −1 , 14.87 emu g −1 , 12.45 emu g −1 , and 87.44 Oe, 94.06 Oe, 102.97 Oe for YM1, YM2, and YM3, respectively. The reflection losses for YM1, YM2, and YM3 are −8.88, −11.64, and −21.39 dB, respectively. The double‐resonance peaks contribute to two magnetic loss peaks in YM3 within a broad frequency range. The higher attenuation constant is observed for YM3 corresponding to a stronger electromagnetic absorption. The improved electromagnetic properties of the composites can be attributed to the synergistic effect between the Ba 1.8 Sr 0.2 Co 2 Fe 11.9 Pr 0.1 O 22 and Ti 3 C 2 T x ‐MXene, which enhances the impedance matching and increases the absorption of electromagnetic waves. These improved electromagnetic properties are important in applications such as electronic devices and communication systems.
