Synthesis of Magnetic Nanocomposite (MnFe2O4 @ SiO2 @ NH2) and Attachment to Acylation of Multi-Walled Carbon Nanotubes and Identification

In this work, superparamagnetic nanocomposite of Manganese ferrite was synthesized, using a co-precipitation method, and to prevent oxidation and increase of OH-functional groups on the surface, nanoparticles were reacted with tetra-orthosilicate and Silica coating was created on the surface of nanoparticles. In order to establish a chemical bond in subsequent reactions, the surface of the nanoparticles were covered and functionalized with 3-amino-propyltrimetoxycycline (APTMS). On the other hand, Multi-Walled Carbon NanoTubes (MWCNTs) with a diameter of 8 nm, increase the reactivity was reacted and functionalized with HNO3 Followed by thionyl chloride. Finally, the magnetic nanoparticles of manganese ferrite with an amine functional group are reacted with acylated  MWCNTs. Magnetic nanoparticles were identified using FT-IR spectroscopy, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Vibrating Sample Magnetometers  (VSM), X-Ray Diffraction (XRD) and Raman spectroscopy (RAMAN).
