Synthesis and Characterization of Imide Functionalized Magnetite-silica Core-shell Nanoparticles

In this paper, the structure of the magnetic core-shell nanoparticles functionalized by an imide group was investigated by a simple co-precipitation method. The Fe3O4 nanoparticles as a super paramagnetic and Non-toxic core it was covered with a layer of silica. The resulting nanoparticle functionalized by amino trie thoxy silane and then by Perylene pigments Ttracrbonic acid anhydride. The magnetic structural and thermal properties of the new imide functionalized nanoparticles investigated. The crystaline structures of the nanoparticles were studied by X-ray diffraction and crystalline size was calculated using the Debye-Scherrer formula. The shape, morphology and The approximate size of the nanoparticles was determined by scanning electron microscopy SEM.The magnetic properties of nanoparticles was investigated by Magnetometer vibrating sample VSM that shown superparamagnetic behavior for the samples. The thermal properties of the new imide functionalized nanoparticles were investigated by thermal analysis TGA. Finally, infrared spectrometer FTIR was used to identify the nanoparticles functionality.
