Simple Method for the Preparation of Fe3O4/MWCNT Nanohybrid as Radar Absorbing Material (RAM)

Abstract

<em>We have successfully prepared Fe₃O₄/MWCNT nanohybrid with a very simple and economical method. Multi-Walled Carbon NanoTubes (MWCNT) encapsulated with Fe₃O₄ nanoparticles were synthesized via pyrolyzing of ferrocene. The sample was characterized with XRD, TEM and Vibrating Sample Magnetometer (VSM). Also, Permeability (µ) and Permittivity (ε) were measured. The reflection-loss was measured at 2-18 GHz with a HP8722ES vector network </em><em>analyzer.</em><em> In 2-18 GHz frequency range (microwave frequency), the dielectric loss (tan δ_E=ε″ / ε′ with an amount between 0.5-0.6) effectively improves via the addition</em><em> of Fe₃O₄/MWCNT nanohybrid</em><em> in the desired composite with paraffin matrix. Therefore, it can be concluded that </em><em>Fe₃O₄/MWCNT nanohybrid</em><em> has good potential to improve microwave absorption and can be used as Radar Absorbing Material (RAM).</em>
