Optical Properties of (PVA-CaO) Composites
نویسنده
چکیده
Polyvinyl alcohol and calcium oxide composites appeared by casting technique. The calcium oxide added to polyvinyl alcohol with different weight percentages are (0,1,2 and 3) wt.%. Results showed that the absorbance increases with increase the weight percentage of calcium oxide. The absorption coefficient, extinction coefficient, refractive index and real and imaginary parts of dielectric constants are increasing with increase calcium oxide concentration.
