Comparative study of chemical, mechanical, thermal and barrier properties of poly(lactic acid) plasticized with epoxidized soybean oil and epoxidized palm oil

To investigate epoxidized palm oil’s (EPO) potential as plasticizer for poly (lactic acid) (PLA), its plasticizing effect was compared with commercialized epoxidized soybean oil (ESO). The plasticizers were respectively melt-compounded into PLA at 3, 5, 10, and 15 wt.%. As it was aimed for the blend...
