In this study, the polymer blend technique was used to improve the amorphous phases of two semi-crystalline polymers. Series of polymer blend films based on polyvinyl alcohol (PVA) and Chitosan (CS) with different compounds were prepared using solution cast technique. The structural characterization of the prepared pure PVA, pure CS, and their blend films was investigated using X-ray diffraction (XRD) technique. The XRD studies indicated that both...
