|dc.description.abstract||Poly (lactic acid) (PLA), a compostable and biodegradable polymer, is a high-brittle polymeric material. Therefore, mechanical property improvement of the PLA is challenging by utilization of natural rubber (NR), a green elastomeric and renewable materials. In this study, NR and chemically modified NR to epoxidized NR (ENR) are explored as impact modifiers for the PLA. The as-prepared ENR with 30 mol% epoxide content (E30NR) and NR are melt-blended with PLA at various rubber contents (1 to 5 wt.%). The result illustrates the concurrent increment in elongation ability and impact performance of PLA, approximately elevenfold and twofold, respectively, with adding 5 wt.% E30NR compared with those of NR/PLA blends with the same rubber content. In addition, the 5 wt.% E30NR is an efficient impact modifier for PLA as the elongation at break and the impact strength is increased approximately fifteen and four times, respectively, compared to the PLA. The E30NR/PLA blends launch superior modulus and strength when compared to NR/PLA blends. Furthermore, E30NR/PLA films transparency demonstrat-ed from transmittance percentage shows higher transparency than NR/PLA blend films. Consequently, NR-based utilization as a mechanical modifier could be considered a sustainable and alternative way for the value-added of NR and increment of PLA’s applications.||en_US|
