Thermoplastic starch films with vegetable oils of Brazilian Cerrado: Thermal characterization

Starch is one of the most promising natural polymers to be abundant, cheap and biodegradable. To get thermoplastic starch (TPS) is necessary mechanical shake, high temperature and use of plasticizers. In this work, TPS films were prepared by casting from cassava starch and three different vegetable...

Zusammenfassung:	Starch is one of the most promising natural polymers to be abundant, cheap and biodegradable. To get thermoplastic starch (TPS) is necessary mechanical shake, high temperature and use of plasticizers. In this work, TPS films were prepared by casting from cassava starch and three different vegetable oils of Brazilian Cerrado as plasticizer: buriti, macauba and pequi. The materials were analyzed by TG, DSC and TMA. Thermal properties of oils depend on their chemical structures. Starch and vegetable oils are natural resources that can be used how alternative to producing materials that cause minor environmental impact.
