In this study, we outline a novel strategy for the synthesis and characterization of single-walled nanotubes (SWCNTs) modified with iron oxide nanoparticles (Fe3O4|Fe2O3|FeO). The synthesis process involves a two-step approach, first attaching SWCNTs onto a suitable substrate and then incorporating Fe3O4 nanoparticles via a solvothermal 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 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 environmental remediation.

Effect of Functionalization on the Magnetic Properties of Fe3O4 Nanoparticles Dispersed in SWCNT Matrix
The chemical properties of iron oxide nanoparticles dispersed within a single-walled carbon nanotube scaffold can be significantly modified by the implementation of functional groups. This tailoring can enhance nanoparticle dispersion within the SWCNT framework, thereby affecting their overall magnetic characteristics.
For example, charged functional groups can facilitate water-based compatibility of the nanoparticles, leading to a more uniform distribution within the SWCNT matrix. Conversely, nonpolar functional groups can reduce nanoparticle dispersion, potentially resulting in assembly. Furthermore, the type and number of chemical moieties attached to the nanoparticles can directly influence their magnetic response, leading to changes in their coercivity, remanence, and saturation magnetization.
