Abstract
Renewable poly(lactic acid) (PLA) exhibits high strength and stiffness. PLA is fully biodegradable and has received great interest. However, the inherent brittleness of PLA largely impedes its wide applications. In this article, the recent progress in PLA toughening using various routes including plasticization, copolymerization, and melt blending with flexible polymers, was reviewed in detail. PLA toughening, particularly modification of impact toughness through melt blending, was emphasized in this review. Reactive blending was shown to be especially effective in achieving high impact strength. The relationship between composition, morphology, and mechanical properties were summarized. Toughening mechanisms were also discussed. © 2011 Wiley Periodicals, Inc. J Polym Sci Part B: Polym Phys, 2011.
As the environmental impact and sustainability of conventional polymer materials becomes of increasing concern, research into polymers from renewable sources is growing. Poly(lactic acid) (PLA) is the most widely investigated, but for use in as many applications as possible its properties must be enhanced. This Review looks at the recent progress in toughening of PLA by plasticization, copolymerization, and melt‐blending with flexible polymers. Reactive blending was shown to be especially effective in achieving super‐toughness.
