| Popis: | In this work, a 3D ternary core–shell Fe3O4@SiO2@MoS2 composite is synthesized by a hydrothermal technique and a modified Stober method, where magnetic Fe3O4@SiO2 microsphere with the core of raspberry-like Fe3O4 nanoparticles is completely coated by the flower-like MoS2. Herein, the electromagnetic parameters of the composites are effectively tuned by the combination of magnetic Fe3O4 with dielectric SiO2 and MoS2. The obtained ternary composites exhibit remarkable enhancement of microwave absorption. The measurement results indicate that the minimum reflection loss (RL) of Fe3O4@SiO2@MoS2 composites reaches −62.98 dB at 1.83 mm with the effective absorption bandwidth (RL |
