Synthesis of Zinc Oxide Nanoparticles by Sol-gel and Effect of Nanorods on hysicochemical Properties of Sago Starch Films

In this research, synthesizing zinc-oxide nanostructures performed with sol-gel method. Also influence of various parameters of this method in how to synthesizing this composition studied. Phase based and morphologic evaluations of powder performed sequentially by X-ray diffraction analysis (XRD) and scanning electron microscope (SEM). Starch film based sago starch and add plasticizers sorbitol/glycerol weight ratio of 3 to 1 by casting method was developed. Zinc oxide nanorod with density of 0, 1, 3 and 5% (w/w) addet to the films before casting and films were dried at controlled conditions. Physicochemical properties such as water absorption capacity (WAC), permeability to water vaper (WVP) and water solubility of the films were measured. Also the effects of addition of nanoparticles were measured on the antimicrobial properties of the films on the surface by Agar diffusion method. Results showed that by increasing concentration of ZnO nanorod, solubility in water, WAC and WVP of the film significantly (p
