The effect of berry paper mulberry on dielectric and optical properties of polyvinyl acetate and polyethylene-glycol has been studied. The optical properties of biocomposites were measured in the wavelength range 190-790 nm. The experimental results showed that the absorbance, absorption coefficient, extinction coefficient, refractive index and real and imaginary dielectric constants of polymer composites are increasing with increasing of berry paper mulberry concentrations. The energy gap of polymer is decreased with increasing of the berry paper mulberry concentrations. The dielectric properties are measured in frequency range 100-5 MHz. The dielectric parameters are increasing with increases of the berry paper mulberry percentages and change with increase of the berry paper mulberry concentration. ER -
