Abstract
A multi-component, special structure of electromagnetic wave absorber produces significant electromagnetic wave absorption performance because of excellent impedance matching. In this work, CoFe2O4 @CNTs composites are prepared. CoFe2O4 exhibits a hollow and open-hole shape with a rough surface, and this structure facilitates more electromagnetic wave absorption. The incorporation of multiwalled carbon nanotubes (MWCNTs) leads to dipole polarization and when wrapped around CoFe2O4 particles, increases the interface loss. The influence of the filler-loading ratio on the microwave absorption performance of wax-based absorbers is thoroughly investigated. The highest electromagnetic wave absorption performance is obtained at 25% filling with a minimum reflection loss (RLmin) of − 36.52 dB at a thickness of 1.9 mm and effective absorption bandwidth (EAB) is 3 GHz. In this study, a method is proposed for creating high-performance electromagnetic wave absorbers.
