In this study, we present a novel strategy for the synthesis and characterization of single-walled carbon nanotubes (SWCNTs) covalently attached with iron oxide nanoparticles (Fe3O4|Fe2O3|FeO). The fabrication process involves a two-step approach, first bonding SWCNTs onto a compatible substrate and then depositing Fe3O4 nanoparticles via a solvothermal method. The resulting SWCNT-Fe3O4 nanocomposites were extensively characterized using a range 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 structured nature of the Fe3O4 nanoparticles, while VSM measurements demonstrated their magnetic click here behavior. These findings suggest that the synthesized SWCNT-Fe3O4 nanocomposites possess promising characteristics for various uses in fields such as biomedicine.

Effect of Functionalization on the Magnetic Properties of Fe3O4 Nanoparticles Dispersed in SWCNT Matrix
The physical properties of magnetite nanoparticles dispersed within a single-walled carbon nanotube scaffold can be significantly influenced by the introduction of functional groups. This functionalization can strengthen nanoparticle dispersion within the SWCNT structure, thereby affecting their overall magnetic behavior.
For example, charged functional groups can promote water-based compatibility of the nanoparticles, leading to a more consistent distribution within the SWCNT matrix. Conversely, hydrophobic functional groups can reduce nanoparticle dispersion, potentially resulting in agglomeration. Furthermore, the type and number of chemical moieties attached to the nanoparticles can significantly influence their magnetic permeability, leading to changes in their coercivity, remanence, and saturation magnetization.
