Synthesis and Characterization of Superparamagnetic Iron Oxide Nanoparticles Prepared With Tween-80

Nasir Muhammad, Muhmmad Iqbal Khan, Muhammad Afzal Kamb, et al


In this study attempt was made to develop a simple low temperature procedure for the synthesis of stable, surface modified superparamagnetic iron oxide nanoparticles (SPIONs) in different phases. Tween-80 was used for surface modification of the SPIONs and as prepared samples were air annealed to study the effect on the phase development. Characterization of the samples was carried out using various techniques such as powder XRD, SEM, EDS, FTIR and UV/Vis spectroscopy; and thermal stability was checked by TGA. From PXRD data of the synthesized NPs, crystallite size came out to be approximately 60 nm and samples were polydispersed in nature. FT-IR spectra confirmed the presence organic surfactant used for surface functionalization of SPIONs. At room temperature, these SPIONs attracted towards the external applied magnet. For the evaluation of thermal stability, TGA curves displayed excellent stability due to role of surfactant used in the synthesis of SPIONs at higher temperatures i.e. up to 1000 ºC.
