In this study, we outline a novel strategy for the synthesis and characterization of single-walled nanotubes (SWCNTs) functionalized with iron oxide nanoparticles (Fe₃O₄|Fe2O3|FeO). The fabrication process involves a two-step approach, first attaching SWCNTs onto a compatible substrate and then depositing Fe₃O₄ nanoparticles via a coprecipitation method. The resulting SWCNT-Fe₃O₄ nanocomposites were extensively characterized using a variety of techniques, comprising transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and vibrating sample magnetometry (VSM). TEM images revealed the uniform dispersion of Fe₃O₄ nanoparticles on the SWCNT surface. XRD analysis confirmed the polycrystalline nature of the Fe₃O₄ nanoparticles, while VSM measurements demonstrated their magnetic behavior. These findings demonstrate that the synthesized SWCNT-Fe₃O₄ nanocomposites possess promising characteristics for various uses in fields such as biomedicine.

Effect of Functionalization on the Magnetic Properties of Fe₃O₄ Nanoparticles Dispersed in SWCNT Matrix

The chemical properties of Fe₃O₄ nanoparticles dispersed within a single-walled carbon nanotube network can be significantly influenced by the incorporation of functional groups. This modification can improve nanoparticle alignment within the SWCNT framework, thereby affecting their overall magnetic performance.

For example, charged functional groups can promote water-based solubility of the nanoparticles, leading to a more consistent distribution within the SWCNT matrix. Conversely, hydrophobic functional groups can reduce nanoparticle dispersion, potentially resulting in assembly. Furthermore, the type and number of functional groups attached to the nanoparticles can significantly influence their magnetic permeability, leading to changes in their coercivity, remanence, and saturation magnetization.
