In this study, we describe a novel strategy for the synthesis and characterization of single-walled nanotubes (SWCNTs) functionalized with iron oxide nanoparticles (Fe3O4|Fe2O3|FeO). The synthesis process involves a two-step approach, first bonding SWCNTs onto a compatible substrate and then incorporating Fe3O4 nanoparticles via a coprecipitation method. The resulting SWCNT-Fe3O4 nanocomposites were thoroughly 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 uniform dispersion of Fe3O4 nanoparticles on the SWCNT surface. XRD analysis confirmed the polycrystalline nature of the Fe3O4 nanoparticles, while VSM measurements demonstrated their superparamagnetic behavior. These findings indicate that the synthesized SWCNT-Fe3O4 nanocomposites possess promising characteristics for various deployments in fields such as environmental remediation.

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 scaffold can be significantly modified by the incorporation of functional groups. This modification can improve nanoparticle dispersion within the SWCNT structure, thereby affecting their overall magnetic behavior.
For example, polar functional groups can enhance 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 agglomeration. Furthermore, the type and number of chemical moieties attached to the nanoparticles can directly influence their magnetic permeability, leading to changes in their coercivity, remanence, and saturation magnetization.
