In this study, we outline 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 immobilizing SWCNTs onto a appropriate substrate and then incorporating Fe₃O₄ nanoparticles via a hydrothermal method. The resulting SWCNT-Fe₃O₄ nanocomposites were thoroughly characterized using a range 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 ferromagnetic behavior. These findings demonstrate 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 magnetic properties of magnetite nanoparticles dispersed within a single-walled carbon nanotube scaffold can be significantly influenced by the incorporation 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 uniform distribution within the SWCNT matrix. Conversely, hydrophobic functional groups can limit nanoparticle dispersion, potentially resulting in assembly. Furthermore, the type and number of functional groups attached to the nanoparticles can directly influence their magnetic permeability, leading to changes in their coercivity, remanence, and saturation magnetization.
