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

Abstract

Ba1.8Sr0.2Co2Fe11.9Pr0.1O22/Ti3C2Tx‐MXene composites are synthesized with the unique combination of magnetic and conducting components that enhance electromagnetic wave absorption. Ba1.8Sr0.2Co2Fe11.9Pr0.1O22, Ti3C2Tx‐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, Ba1.8Sr0.2Co2Fe11.9Pr0.1O22 particles are confirmed to be well‐integrated with the Ti3C2Tx‐MXene, indicating that the Ba1.8Sr0.2Co2Fe11.9Pr0.1O22 particles are evenly distributed in the Ti3C2Tx‐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 Ba1.8Sr0.2Co2Fe11.9Pr0.1O22 and Ti3C2Tx‐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.
