Preparation and characterization of γ-Fe₂O₃ dispersed polyvinyl alcohol (PVA) Nanocomposite film

Nanoscaled γ-Fe₂O₃ particles showing supermagnetic behavior have been widely studied in recent years for various applications. γ-Fe₂O₃ dispersed nanocomposites wide applications have attracted many researchers to study their different nature when they are dispersed into polymers matrix. γ-Fe₂O₃ nanoparticles dispersed polyvinyl alcohol (PVA) nanocomposite has many applications in medical field such as drug delivery, magnetic gels, in cancer treatment, and also in memory devices, supermagnetic materials and many more. In the present study we prepared the nano sized γ-Fe₂O₃ dispersed polyvinyl alcohol (PVA) nanocomposite (FPN) film, in the various ratios. These nanocomposites were characterized to understand the molecular structure through FT-IR spectroscopy, magnetic property employing vibrating sample magnetometer, thermal study employing TGA, DSC and the morphology through Scanning Electron Microscopy (SEM) technique. Through the mentioned characterizations we understood the formation of a well dispersed γ-Fe₂O₃ nanoparticles PVA nanocomposite film, with chemical homogeneity.
