Abstract
Magnetite nanoparticles (Fe3O4 NPs) are prepared using chemical reduction method. This is a simple, economical, nontoxic, facile, clean, and environment friendly process. Preparation of composite polymeric membrane of polyvinyl alcohol (PVA)/Fe3O4 has been performed using dry phase inversion technique for different medical/filtration applications. PVA coatings using magnetite NPs are focused to passivate the surface and decrease agglomeration and also reduce module biomedical absorption and most of the times increase dispersion stability. Therefore, research on PVA coatings on magnetite NPs are in trend now a days, as they are of high charge density that makes them stable in dispersion by electrostatic repulsion. The prepared samples (Fe3O4 NPs) and PVA/Fe3O4 composite membrane have been analyzed for their different properties by using X-ray direction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), ultraviolet–visible spectroscopy (UV–Vis) and thermogravimetric Analysis (TGA).
