Optical Properties of PVA-BaSO4.5H2O Composites

Raheem G. Kadhim, Mohammed A. Razooqi, Rasha A. Abdullah, Fadhil K. Flaifil


Composites consisting of a polyvinyl alcohol matrix and BaSO4.5H2O as filler are designed. The optical properties were measured in the wavelength range from (190-850) nm. The experimental results showed that the absorption coefficient, extinction coefficient, refractive index and real and imaginary parts of dielectric constants are increasing with increase the addition of BaSO4.5H2O content.

Keywords: Polyvinyl alcohol, Optical constants, Composites.
