Effect of lactic acid as plasticizing agent on the tensile and biodegradable properties of corn cob powder/polyvinyl alcohol blend film

In this study, the blended film was prepared from a PVA/CCP/lactic acid blended film using the solution casting method. Blended was prepared by modifying the composition of lactic acid using the one-factor-at-a-time (OFAT) method. Attenuated total reflectance (ATR) spectroscopy was used to identify...
