Synthesis of Fe3O4@SiO2@C/Ni microspheres for enhanced electromagnetic wave absorption
Source abstract
Abstract
With the rapid development of electromagnetic and radar technology, military stealth technology has become an essential measure of a country`s military strength. In this paper, hydrothermal and improved Stober methods prepared the composite absorbing material Fe 3O 4@SiO 2@C/Ni with a double core-shell structure. The minimum reflection loss of the sample is −38.9 dB, and the maximum effective bandwidth is 10.1 GHz. By changing the thickness of the carbon layer and the thickness of the SiO 2 layer, the absorption performance of the prepared sample can be adjusted to achieve the best impedance matching. The synergistic effect of the composite`s dielectric loss and magnetic loss improves its microwave absorption capacity, making it a promising choice for absorptive material applications.
