Abstract :
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
analyzer. In 2-18 GHz frequency range (microwave frequency), the dielectric loss (tan δE=ε″ / ε′ with an
amount between 0.5-0.6) effectively improves via the addition of Fe3O4/MWCNT nanohybrid
in the desired composite with paraffin matrix. Therefore, it can be concluded that Fe3O4/MWCNT
nanohybrid has good potential to improve microwave absorption and can be used as Radar
Absorbing Material (RAM).
