MODULATING THE ELECTRICAL PROPERTIES OF HEMATITE NANOSTRUCTURES WITH FUNCTIONALIZED CARBON NANOTUBES

S.A. Guluzade, N.N. Musayeva

ABSTRACT

This paper investigates the effect of functionalized carbon nanotubes (f-MWCNTs) on the electrical properties of nano-sized Hematite (Fe₂O₃) structures. Fe₂O₃ nanoparticles were synthesized using a simple sol-gel method, and 10 wt.% of f-MWCNTs were incorporated into this matrix with the assistance of ultrasound waves. The resulting nanocomposite was analyzed using XRD and FTIR spectroscopy methods. TEM analysis revealed that spherical nanoparticles were distributed on the carbon nanotubes, and decorating their surfaces. The electrical properties of Fe₂O₃, f-MWCNTs, and Fe₂O₃-f-MWCNTs nanocomposites were studied, and it was found that by adding a certain amount of f-MWCNTs to Fe₂O₃ using the above-described method, the electrical properties of the resulting nanocomposite were significantly improved.
