Preparation and Characterization of (PVA-FeNO3) Composites

This works investigate the effects of addition FeNO3 on optical properties of poly-vinyl alcohol(PVA). The specimens were prepared by adding FeNO3 to the solution of poly-vinyl alcohol with weight percentages from FeNO3 are(0,1,2,3)wt.%. The experimental Results show that the absorbance of (PVA-FeNO3)composites increases with increase the weight percentages of FeNO3. The refractive index, real part of dielectric constant, Berwster angle and coefficient of finesses are increasing with increase weight percentages of FeNO3
