Abstract :
The present research aimed to study the energy band gaps of Chitosan (CS) -Polyvinyl Alcohol (PVA) blend films crosslinked with Potassium nitrate (KNO3). The morphology of the film surface and blending were investigated by Scanning Electron Microscopy (SEM). The UV-visible spectroscopic studies were done by Parking Elmer UV/Vis Spectrometer Lamda-35. The increase in the absorption intensity and decrease in the optical band gap may be due to a larger absorption increment associated with the charge transfer transition and a similarly Optical conductivity of samples increases due to the decrease in optical band gap and hence promises to be a good material for the biomedical and battery applications.

Key-Words / Index Term :
Chitosan-Polyvinyl Alcohol blend, Potassium nitrate, absorption maxima, direct and indirect energy band gap
