Preparation and Characterization of (PVA-FeNO3) Composites

Abstract

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.
