ENHANCEMENT OPTICAL PROPERTIES OF CARBOXYMETHYL CELLULOSE BIOPOLYMER COMPOSITE FILMS DOPED WITH CHROMIUM CHLORIDE
Abstract
Polymers are used in a wide range of manufacture applications for their low cost, light weight, mechanical and optical properties. In this paper, optical properties were studied by various experimental techniques in order to understand the impact of the chromium chloride metal salt on the biopolymer CMC properties. The chromium chloride was add to carboxymethyl Cellulose with weight percentages are (0, 1, 5, 9, 13) wt%. The absorption and transmission spectra has been recorded in the wavelength range (190-1100) nm. The experimental results showed that the absorption coefficient, optical energy gap, extinction coefficient, refractive index and real and imaginary dielectric constant effected by addition different weight percentages from chromium chloride.
