INFLUENCE OF STARCH SOURCE ON PROPERTIES OF BLENDS BASED ON THERMOPLASTIC STARCH AND POLY(BUTYLENE-ADIPATE-CO-TEREPHTHALATE)

This work aims to develop and characterize blends of thermoplastic starch (TPS) modified with citric acid and poly(butylene-adipate-co-terephthalate) (PBAT), using sweet potato (SP) and cassava (C) as starch sources. The blends were produced through extrusion, combining thermoplastic starch with PBA...

description This work aims to develop and characterize blends of thermoplastic starch (TPS) modified with citric acid and poly(butylene-adipate-co-terephthalate) (PBAT), using sweet potato (SP) and cassava (C) as starch sources. The blends were produced through extrusion, combining thermoplastic starch with PBAT, and characterized using Infrared Absorption Spectroscopy, X-ray diffraction, a scanning electron microscope, tensile testing, and swelling analyses. The starch granules from SP and C showed variations in structure and composition (specifically in the amylose-to-amylopectin ratio), influencing the morphology and properties of the blends. The TPS-SP/PBAT blends exhibited greater resistance and lower hydrophilicity compared to the TPS-C/PBAT blends. Variations in the properties of the blends were also observed with different amounts of the biodegradable polyester used. The developed blends offer a long-term sustainable alternative to conventional polymers in the manufacturing of disposable packaging for the food industry.
