PREPARATION OF PVP MODIFIED CoFe2O4 NANOPARTICLES AND ITS DISPERSION IN ETHANOL
Journal Title: Indian Journal of Scientific Research - Year 2017, Vol 8, Issue 1
Abstract
In this paper CoFe2O4 ultrafine particles of 2nm have been prepared by precipitation method and modified by Poly-vinyl pyrrolidone (PVP). Confirmation of the formation of PVP@CoFe2O4 (PVP modified CoFe2O4) was characterized by XRD, EDX and FTIR comprised analysis. And the size, shape, nature of sample was analyzed and discussed using TEM, XRD. Hydrodynamic size was characterized by PSD-DLS after the ultrasonic ton treatment on the dispersed PVP/CoFe2O4 powder in an ethanol which has been compared to the TEM and XRD estimate. The zeta-potential and conductivity have been analyzed for the varying weight concentration of powder in ethanol dispersion. The nature of PVP@CoFe2O4 powder in ethanol dispersion in term of shift was analyzed using the zeta potential and rendering this study to the stability and the nature for the negative and positive potential.
