Abstract
Massive efforts have been focused on effective electromagnetic absorbing materials, which have promising applications in suppressing or eliminating the electromagnetic radiation. In this study, Fe3O4@SiO2@PPy composites were prepared via a facile one-pot polyreaction. The results demonstrate that the composites loaded with 30â¯wt% possess an excellent electromagnetic absorbing property. Specifically, the minimum reflection loss value isâ¯â56.90â¯dB at 10.41â¯GHz at an absorber thickness of 3.7â¯mm. The broadest effective frequency bandwidth (reflection loss less thanâ¯â10â¯dB) is 6.38â¯GHz at an absorber thickness of 3â¯mm. The outstanding performance implies that the Fe3O4@SiO2@PPy composites have a huge potential for application as advanced electromagnetic absorber with the advantages of strong absorption, wide bandwidth and low density.
