Abstract

The innovation in microwave absorbing material has increased exponentially to support telecommunication technology. Fe₃O₄ could be one candidate for absorber material; however, Fe₃O₄ still has lower permeability at high frequency and high density; thus, it fails to meet one of MAM's ideal characteristics. In this research, we try to make an excellent microwave absorber material by combining conventional microwave absorber Fe₃O₄ with multi-walled carbon nanotubes and TiO₂ (Fe₃O₄/MWCNT/TiO₂ nanocomposites). Structural characterization results strongly suggested that the Fe₃O₄/MWCNT/TiO₂ nanocomposites have been successfully fabricated. The nanocomposite presented superparamagnetic properties and has a band gap energy range between 2.236 and 2.255 eV, which is suitable for microwave absorbers. We found that increased TiO₂ concentration in the nanocomposite enhanced the microwave absorption performance. The maximum reflection loss of this study was 44.3 dB with thicknesses of 20 mm, in which 99% of the microwave was absorbed by Fe₃O₄/MWCNT/TiO₂, indicating excellent microwave absorption performance.
