title = "Effect of citric acid on physical and mechanical properties of Starch/PLA/PVA bioplastic films",
abstract = "The bioplastics synthesized from starch which is low physical and mechanical properties. Blending polymer (PLA Grafting and PVA Addition) and chemical modification by crosslinking have been investigated as strategies to improve the physical and mechanical properties of bioplastic films. A series of Starch/PLA/PVA films with varying concentration (0-25%, w/w) of citric acid was synthesized by casting method. The improvement in physical and mechanical properties consists of swelling and solubility, biodegradability, tensile strength and elongation percentage of blend films was evaluated as compared to bioplastic without crosslinker. 5% citric acid showed the most optimum concentration to improve the physical and mechanical properties of bioplatics. The blend bioplastics were characterized using Fourier transform infrared spectrophotometry (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA/DTA) and X-Ray diffraction (XRD). The result showed that addition of 5% citric acid also increased crystallinity and temperature glass (Tg), and reduced brittleness the surface morphology of bioplastic films.",
