? 2022 Elsevier B.V.The core@shell structures and compositions hold greatly potential for microwave absorption. Herein, the Fe3O4@1T/2H-MoS2 nanocomposites with core@shell structures were successfully fabricated through a simple hydrothermal process. The impedance matching was significantly promoted by introducing magnetic Fe3O4 nanoparticles and designing the flower-like 1 T/2 H-MoS2 with core@shell structures. It can be seen that the regulation of Fe3O4 contents play an important role in electromagnetic parameters and microwave absorption performances of the Fe3O4@1T/2H-MoS2 nanocomposites with core@shell structures. The Fe3O4@1T/2H-MoS2 nanocomposites with core@shell structures with corresponding thickness of 2.67 mm display the minimum reflection loss (RLmin) value of ? 56.22 dB at 10.36 GHz (in X band), and the maximum absorption bandwidth (ABmax) extend up to 4.76 GHz with thickness of only 1.89 mm. This result is of great significance for improving microwave absorbing performance, and the nanocomposites can be regarded as candidates for high-quality absorbing materials.
