In this study, equal weight percent of poly(vinyl alcohol) (PVA)/poly(vinyl pyrrolidone) (PVP) blend solutions filled with different weight percent of chitosan (CS) up to 12 wt% were prepared by solution blending followed by solvent evaporation technique in the form of film. The prepared poly(vinyl alcohol) (PVA)/poly(vinyl pyrrolidone) (PVP)/chitosan (CS) ternary blend films of different weight percentage compositions were characterized by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The results obtained show an increase in glass transition temperature of the blend films with increasing chitosan content.
