| Description | Journal: Iop Conference Series: Materials Science and Engineering Flake FeNi alloys were fabricated by micromachining, $CoFe_{2}O_{4}$ and PANI were loaded on the surface of the flake FeNi alloys by coprecipitation and in-situ polymerization. Finally the $FeNi/CoFe_{2}O_{4}$/PANI composites with electromagnetic absorption properties were obtained. The morphology, composition and microwave absorbing properties of the composites were studied by SEM, XRD, FTIR and VNA. The results showed that $CoFe_{2}O_{4}$/PANI is deposited on the surface of the matrix, and a small amount was dissociated. The permittivity and the low-frequency absorbing property of the composites was improved. At the frequency of 2.2GHz, the lowest reflection reached -12.2dB. By analyzed the electromagnetic properties and using the theory of 1/4 wavelength interference cancellation, the reasons for the improvement of low frequency absorbing properties of composites were explained. |
