In this study, we outline a novel strategy for the synthesis and characterization of single-carbon nanotube nanotubes (SWCNTs) covalently attached with iron oxide nanoparticles (Fe3O4|Fe2O3|FeO). The fabrication process involves a two-step approach, first bonding SWCNTs onto a suitable substrate and then introducing Fe3O4 nanoparticles via a coprecipitation method. The resulting SWCNT-Fe3O4 nanocomposites were rigorously characterized using a combination of techniques, encompassing 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 indicate that the synthesized SWCNT-Fe3O4 nanocomposites possess promising properties for various applications 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 scaffold can be significantly altered by the introduction of functional groups. This functionalization 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 homogeneous distribution within the SWCNT matrix. Conversely, nonpolar functional groups can reduce nanoparticle dispersion, potentially resulting in agglomeration. Furthermore, the type and number of surface ligands attached to the nanoparticles can indirectly influence their magnetic response, leading to changes in their coercivity, remanence, and saturation magnetization.
