In this study, we describe a novel strategy for the synthesis and characterization of single-carbon nanotube nanotubes (SWCNTs) functionalized with iron oxide nanoparticles (Fe3O4|Fe2O3|FeO). The synthesis process involves a two-step approach, first bonding SWCNTs onto a appropriate substrate and then introducing Fe3O4 nanoparticles via a hydrothermal method. The resulting SWCNT-Fe3O4 nanocomposites were extensively characterized using a variety of techniques, including transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and vibrating sample magnetometry (VSM). TEM images revealed the homogeneous dispersion of Fe3O4 nanoparticles on the SWCNT surface. XRD analysis confirmed the crystalline nature of the Fe3O4 nanoparticles, while VSM measurements demonstrated their superparamagnetic behavior. These findings suggest that the synthesized SWCNT-Fe3O4 nanocomposites possess promising potential for various deployments in fields such as biomedicine.

Effect of Functionalization on the Magnetic Properties of Fe3O4 Nanoparticles Dispersed in SWCNT Matrix
The chemical properties of magnetite nanoparticles dispersed within a single-walled carbon nanotube network can be significantly influenced by the introduction of functional groups. This functionalization can strengthen nanoparticle dispersion within the SWCNT environment, thereby affecting their overall magnetic performance.
For example, charged functional groups can enhance water-based compatibility of the nanoparticles, leading to a more homogeneous distribution within the hydrophobic silica nanoparticles SWCNT matrix. Conversely, alkyl functional groups can limit nanoparticle dispersion, potentially resulting in assembly. Furthermore, the type and number of surface ligands attached to the nanoparticles can indirectly influence their magnetic permeability, leading to changes in their coercivity, remanence, and saturation magnetization.
