| description | Thinness, lightness, width, strength are people's pursuit of efficient electromagnetic wave (EMW) absorption materials. Fe/Fe3C/Fe3O4@C magnetic microspheres were prepared by high temperature calcination of food-grade ferric citrate and source through hydrothermal reaction. By changing the molar ratio of ferric citrate and sucrose, the influence of the content of ferric citrate on the EMW absorption performance of the composite was investigated, and the electromagnetic parameters were effectively controlled to optimize impedance matching. The experimental results show that when the molar ratio of iron citrate and sucrose is 5:3, it has better EMW absorption performance: when the thickness is 2.5 mm, the minimum reflection loss (RL) is -50.17 dB, and the effective absorption band width less than -10 dB is 3.52 GHz. The excellent EMW performance is mainly due to the synergistic effect of the rich interface, porous structure and magnetic properties of Fe/Fe3C/Fe3O4. |
