摘要：Poymer blends using chitosan and polyvinyl alcohol were prepared in the presence of peroxide ashardening agent. Peroxide improves the properties of polymer film. The prepared blends were characterised by X-raydiffraction, scanning electron microscopy, thermal studies, tensile and water absorption measurement. The XRD resultsshow that the film containing higher content of polyvinyl alcohol has more crystalline character compared to the other.In thermal analysis it was found that when the amount of polyvinyl alcohol increases the thermal stability of filmincreases. SEM micrographs taken from the surface of sample illustrate a uniform dispersion of chitosan inside thematrix. When the amount of chitosan increases agglomeration of particles takes place which decreases the properties.In tensile studies when the amount of polyvinyl alcohol increases the tensile strength increases with decreases inelongation percentage. Moreover, addition of hydrogen peroxide to the blends increases the mechanical properties.
