Effect of MgCl2 dopant on optical properties of tamarind gum based biopolymer electrolytes
Abstract
Recent research on biopolymers based on magnesium salts is scarce in the existing literature. In the current research study, solution-casting technique was used for the preparation of solid biopolymer electrolytes, using Tamarind Seed Polysaccharide (TSP) as the host biopolymer, which was doped with several varying concentrations of magnesium chloride (MgCl2). UV-visible spectroscopic method was used to investigate the thermal and optical parameters in the wavelength range of 200 nm to 800 nm. From the study of optical absorption parameter, the values of optical transmission, optical refractive index, optical absorption coefficient and optical extinction coefficient were calculated. These parameters revealed optimum values for the film of composition TSP:MgCl2 (70:30 wt.%).
