Abstrakt: Pure and ZnSe nano-particle doped Sodium Alginate (NaAlg) nano-composite films were prepared using solution casting method. The prepared films were characterized using different techniques. The FTIR study shows that the shifts in the bands position upon doping, confirms the chemical modifications that takes place within the polymer nano-composite. This change in the FTIR results is attributed to the formation of complex due to the interaction of dopant and polymer. The XRD results show the variation in degree of crystallinity with increase in dopant concentration indicates the dopant modifies the structure of the polymer film. The presence of the complexes within the nano-composite creates cracks on the surface of the polymer and is studied by FESEM analysis. The electrical study shows that the DC conductivity of the polymer nano-composite increases with increase in the doping level and the highest conductivity is found to be 4.757×10−3 S/cm for 1 Wt.%.
