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 appropriate substrate and then depositing Fe3O4 nanoparticles via a hydrothermal method. The resulting SWCNT-Fe3O4 nanocomposites were thoroughly characterized using a combination of techniques, comprising 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 structured nature of the Fe3O4 nanoparticles, while VSM measurements demonstrated their magnetic behavior. These findings demonstrate that the synthesized SWCNT-Fe3O4 nanocomposites possess promising potential for various uses in fields such as electronics.

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 scaffold can be significantly modified by the incorporation of functional groups. This functionalization can enhance nanoparticle distribution within the SWCNT structure, thereby affecting their overall magnetic characteristics.
For example, charged functional groups can enhance water-based dispersion of the nanoparticles, leading to a more consistent distribution within the SWCNT matrix. Conversely, alkyl functional groups can hinder nanoparticle dispersion, potentially resulting in assembly. Furthermore, the type and number of surface ligands attached to the nanoparticles can significantly influence their magnetic response, leading to changes in their coercivity, remanence, and saturation magnetization.
