Abstract
Searching forhigh efficiency microwaveabsorbersis to meet the requirements ofelimination of electromagnetic pollution. Herein, the Ni0.5Co0.5Fe2O4 decorated pomelo peel-carbon microwave absorber with uniform particle size was prepared by a facile physical blending method. The skeleton structure formed by biomass carbon (BC) can not only effectively improve the conductive loss, but also extend the propagation path of electromagnetic waves. Besides, the absorber with a great quantity defects and heterogeneous interfaces delivers interfacial polarization and dipole polarization. Also, the Ni0.5Co0.5Fe2O4 particles with good dispersion on BC are beneficial toward dielectric-magnetic combination, resulting in impedance matching. The minimum reflection loss (RL) reaches −41.6 dB and the effective absorption bandwidth (EAB) (RL < −10 dB) is 4.3 GHz with the thickness of 3 mm. This work will promise a good approach to accomplish high performance of microwave absorption.
