Abstract

In this study, biodegradable film based on Starch-Kefiran-ZnO was made by casting method. The produced films contain different content of nano ZnO (ZN) (1%, 3%, and 5% wt. ). Also ZN dispersed by ultrasonic homogenizer and added to the Starch-Kefiran solution. Surface characteristics, thickness, moisture content, water vapor permeability and mechanical properties were investigated. In the images of water droplets, it was observed that the contact angle of Starch-Kefiran was 89. 67 degrees. By increasing the amount of zinc oxide nanoparticles up to 1%, the contact angle increased significantly to 95. 63 degrees, which means improving the surface properties and hydrophobicity. The water vapor permeability for Starch-kefir film (×10− 10 g m-1s− 1Pa− 1) was 3. 12, which was increased to 2. 03 (×10− 10 g m-1s− 1Pa− 1) by increasing the concentration of zinc oxide up to 3%. Tensile strength and Young’ s modulus of the specimens were increased by increasing ZN content up to 3%. On the other hand, elongation at break of the Nanocomposites was decreased, simultaneously. It is obvious that, ZN was improved some of the packaging properties of the Starch-Kefiran film.
