Abstract

A new polymer was synthetized based on the Chitosan polymer. The structural and optical and properties of the films have been investigated The X-ray diffraction (XRD) measurements showed that the powder is amorphous for CH-BHM. The thermal stability of CH-M derived polymer was investigated using TGA measurements. TGA analysis showed that polymer was stable from room temperature up to 373 K. The optical properties of thin films were investigated using the spectrophotometric measurements. The absorption spectrum and The absorption coefficient, α, were determined. The values of the optical energy gap Eg of the compound under test was found to be 5.24 eV. The presence of the localized states in the forbidden gap (Urbach tail) was investigated.A new polymer was synthetized based on the Chitosan polymer.
