摘要：
Poly lactic acid (PLA) was reinforced with various compositions of talc with plasticizers polyethylene glycol 1500 (PEG1500) and polyethylene glycol 6000 (PEG6000). These reinforced PLA were prepared by melt mixing technique using twin screw extruder. The prepared composite plastic materials were characterized by using mechanical, morphology, and thermal properties. The polylactic acid-talc-PEG1500 composites (PTP1500) show significant increase in flexural strength from 80MPa to 140MPa. Further the impact strength was also increased to the maximum of 23KJ/m(2). PTP1500 showed a better result when compared with Poly lactic acid reinforced with talc and PEG6000 (PTP6000). (c) 2017 Elsevier Ltd. All rights reserved.
