Studying the Effect of Nicl2 Addition on the Optical Properties of Synthesized Chitosan

Abstract

In this research natural bio polymer "chitosan" was synthesized using fish shells, Chitosan is made from chitin by a chemical process involving demineralization (DA), deproteinization (DP) and deacetylation (DA). Chitosan was doped with (NiCl 2 ) by using casting method. The effects of addition of nickel chloride concentration optical properties of chitosan have been studied in the wavelength range (200-800) nm. The absorption coefficient, energy gap, refractive index and extinction coefficient have been determined. The results show that the optical constants change with increase of nickel chloride concentration.

Spinach Ferredoxin (Fdx) as an Organic Material to Improve Optical Band Gap of Chitosan (Cs) Biofilm

“…Chitosan is one of the conducting polymers that received a great recognition being used in varies fields which including optical application, sensors, biomedical, water treatment and more [4]. Though a great deal of excellent work has been reported on chitosan for optoelectronic applications [5][6][7][8], it is still meaningful to extend the research of these materials [8]. Therefore, in this study, incorporation of organic material (spinach-ferredoxin) into chitosan has been attempted to further improve the optical properties of the films.…”
