Abstract
Conductive polymer coated Y3Fe5O12 (YIG)/NiFe2O4 (NFO) hybrid radar absorbing composites were studied in this work. The magnetic YIG and NFO particles were synthesized by sol–gel method, and then covered with a conductive PANI polymer by in-situ polymerization technique. The structural and magnetic properties of produced particles and hybrid composites were studied by XRD, SEM and VSM measurements. The microwave property of the hybrid composites reinforced in the epoxy matrix was studied in the X-band frequency range. The electromagnetic wave absorbing bandwidth in the X-band increases with the content of YIG in the hybrid composites. A broadband radar absorbing has been observed in EPYN08 and EPYN10 hybrid composites having entire X-band with an absorption criterion of − 10 dB. The maximum reflection loss (RL) value was found as − 35.1 dB at 10.8 GHz frequency in EPYN06 sample. The nanocomposite structures formed by combining magnetic and dielectric materials show better electromagnetic wave absorption properties rather than the each components in the composites. Hence, the experimental results of hybrid composites may be a promising candidate for radar and defense vehicles due to their fully absorbing property in the X-band.
