Smart Film Based on Polylactic Acid, Modified with Polyaniline/ZnO/CuO: Investigation of Physicochemical Properties and Its Use of Intelligent Packaging of Orange Juice

In this study, a biodegradable/conducting film based on polylactic acid (PLA) modified with polyaniline, zinc oxide, and copper oxide (PLA/PAn/CuO/ZnO) was prepared. The effect of the electrical, physicochemical, antioxidant, antimicrobial properties films by different techniques such as SEM, FTIR, TGA were investigated. Electricity conductive used for intelligent packaging orange juice. chemical microbial juice electrical conductivity during storage time (56 days) results showed that greatly increased antioxidant film. Polyaniline gave good conductivity, but had no significant it. active to package viability resistance over mathematical relationship established between changes in resistance, which estimate shelf life expiration date Examination performance these an accuracy 90% have ability conductive/antimicrobial/antioxidant has increase detect spoilage
