The Effect of NiNO3 on Optical Properties for (PVA- PEG) Composites Polymers
Abstract
The present paper is aimed to modification of the optical properties of poly-vinyl alcohol and poly-ethylene glycol with different concentrations of ( NiNO3). The absorption and transmission spectra have been recorded in the wavelength range (200-800)nm . The absorption coefficient and energy gap of the indirect allowed and forbidden transition have been determined, Also, extinction coefficient, index coefficient, real and imaginary part of dielectric constant have been calculated.
Keywords: optical properties, polymer composites, optical constants, polyethylene glycol.
