In this study, we outline a novel strategy for the synthesis and characterization of single-walled carbon nanotubes (SWCNTs) functionalized with iron oxide nanoparticles (Fe₃O₄|Fe2O3|FeO). The synthesis process involves a two-step approach, first bonding SWCNTs onto a appropriate substrate and then incorporating Fe₃O₄ nanoparticles via a solvothermal method. The resulting SWCNT-Fe₃O₄ nanocomposites were extensively 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 structured nature of the Fe₃O₄ nanoparticles, while VSM measurements demonstrated their ferromagnetic behavior. These findings suggest that the synthesized SWCNT-Fe₃O₄ nanocomposites possess promising properties for various applications in fields such as environmental remediation.

Effect of Functionalization on the Magnetic Properties of Fe₃O₄ Nanoparticles Dispersed in SWCNT Matrix

The physical properties of iron oxide nanoparticles dispersed within a single-walled carbon nanotube scaffold can be significantly altered by the implementation of functional groups. This functionalization can improve nanoparticle distribution 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, nonpolar functional groups can limit nanoparticle dispersion, potentially resulting in agglomeration. Furthermore, the type and number of surface ligands attached to the nanoparticles can significantly influence their magnetic permeability, leading to changes in their coercivity, remanence, and saturation magnetization.
