Structural and Optical Properties of (PVA/PVP:Sr2NO3) Nanocomposites
Doaa E. Al-Kateb , Ali R. Abdulridha
Abstract
In this study preparing and investigating of the (PVA/PVP:Sr2NO3) nanocomposites films by using casting method with
different concentration of Sr2NO3 as (0, 1, 3, 5, and 7 wt. %). Optical properties obtained by UV-Vis spectrometer, OM
and FTIR spectra have been revealed in this study, the absorbance increased by increasing of Sr2NO3 nanoparticles
concentrations, the energy-gap (allowed and forbidden) transitions decreased by increasing of the nanoparticles
concentration
Keywords
SR2NO3 Nanoparticle, Polyvinyl Alcohol, Polyethylene Glycol.
