ABSTRACT

High-entropy alloy/polypyrrole (HEA/PPy) composites were synthesized by magnetic stirring at room temperature. The crystal structures, surface morphologies and electromagnetic parameters were analysed. The experimental results show that the composites with 12 ml PPy content present excellent microwave absorbing properties due to the interface loss and good impedance matching. The minimum reflection loss is − 45.28 dB, which is achieved when the thickness is 2.40 mm, and the effective bandwidth is 6.64 GHz. The HEA/PPy composites develop high-efficiency HEA-based electromagnetic wave absorber and have promising for application. More... »
