Resumo

The aim of this research was to study the heat distortion temperature, oxygen transmission rate and water vapor transmission rate of PLA/PBAT/ENR ternary blends. Climate change, pollution, and depletion of natural resources are pressing global environmental issues. As the urgency of these issues increases, the need for sustainable alternatives becomes more apparent. Hence, the biodegradable plastics still have a limitation, i.e. high cost. This research studied methods of lowering the cost of biodegradable plastic and of improving its properties by using epoxidized natural rubber as another polymer of polymer blends. Then, ternary blends of poly (lactic acid), epoxidized natural rubber and poly (butylene adipate-co-terephthalate) were investigated and prepared by using twin-screw extruder, followed by use of a blown film extruder to fabricate biodegradable films.  The proportion of ENR in the ternary blends was fixed at 10 wt%, with the remainder being PLA and PBAT. Moreover, the heat distortion temperature, oxygen gas transmission rate, and water vapor transmission rate were investigated.
