Optical Properties of (PVA-PEG-PF, PP) Composites

The aim of this paper, study of the effect of Palm fronds and Pomegranate peel on optical properties of (PVA-PEG) composites. The Palm fronds and Pomegranate peel were added to the polymers (polyvinyl alcohol 0.85 and Polyethylene glycol 0.15) with weight percentages are (0, 2, 4, 6) wt. %. . The optical properties were measured in the wavelength range (200-800) nm. The results show that the absorbance (A), absorption coefficient (), extinction coefficient (k), refractive index (n) and real and imaginary dielectric constants (1 and 2) of polymers are increasing with the increase of the weight percentages of Palm fronds and Pomegranate peel. The energy gap (Eg) of polymers is decreased with the increase of the Palm fronds and Pomegranate peel concentrations.
