Abstract

Nanocomposites of polyvinyl alcohol- poly-acrylic acid- cobalt oxide nanoparticles have been prepared. The polymer matrix consisting of PVA0.85 and PAA0.15). The cobalt oxide nanoparticles was added to polymers with concentrations are (0, 2, 4 and 6) wt. %. The experimental results show that the absorbance of naoocomposites is increased with the increase of cobalt oxide nanoparticles and optical constants (absorption coefficient, extinction coefficient, refractive index, real and imaginary dielectric constants) of (PVA-PAA-CoO) nanocomposites are increased with the increasing of cobalt oxide nanoparticles concentrations. The energy band gap of nanocomposites is decreased with the increase of cobalt oxide nanoparticles concentrations.
