Majeed Ali, Ahmed Hashim, Safaa Nayyef, Basil Nasih, Farhan Lafta

Abstract: The aims of this paper are preparation of polyvinyl alcohol- poly-acrylic acid- fiber of wheat composites with different for fiber of wheat concentrations by using casting technique and study their optical properties. The results show that the optical properties are changed with increase the fiber of wheat concentrations. The absorbance of (PVA-PAA-FW) composites is increased with increase the fiber of wheat concentrations. The absorption coefficient, extinction coefficient, refractive index, real and imaginary dielectric constants of (PVA-PAA-FW) composites are increasing with increasing the fiber of wheat concentrations. The energy band gap of composites is decreased with increase the fiber of wheat concentrations.

Keywords: composites, fiber, poly-acrylic acid, optical properties
