In this study, we outline a novel strategy for the synthesis and characterization of single-walled nanotubes (SWCNTs) covalently attached with iron oxide nanoparticles (Fe3O4|Fe2O3|FeO). The preparation process involves a two-step approach, first attaching SWCNTs onto a suitable substrate and then incorporating Fe3O4 nanoparticles via a coprecipitation method. The resulting SWCNT-Fe3O4 nanocomposites were extensively 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 uniform 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 suggest that the synthesized SWCNT-Fe3O4 nanocomposites possess promising potential for various applications in fields such as electronics.

Effect of Functionalization on the Magnetic Properties of Fe3O4 Nanoparticles Dispersed in SWCNT Matrix
The magnetic properties of magnetite nanoparticles dispersed within a single-walled carbon nanotube network can be significantly influenced by the incorporation of functional groups. This tailoring can enhance nanoparticle alignment within the SWCNT environment, thereby affecting their overall magnetic performance.
For example, hydrophilic functional groups can facilitate water-based dispersion of the nanoparticles, leading to a more uniform distribution within the SWCNT matrix. Conversely, alkyl functional groups can hinder nanoparticle dispersion, potentially resulting in assembly. Furthermore, the type and number of chemical moieties attached to the nanoparticles can directly influence their magnetic susceptibility, leading to changes in their coercivity, remanence, and saturation magnetization.
