摘要
Abstract
Biodegradable composites were prepared with blending poly (lactic acid)(PLA) with poly (butylene adipate-co-terephthalate)( PBAT), poly (butylenes succinate)(PBS) and poly (propylene carbonate)(PPC) respectively, and then were molded into standard splines. The tensile properties, impact properties and fractured surfaces microstructure of the three kinds of composites were Investigated. The results indicate that PBAT, PBS and PPC can improve the elongation at break and impact strength of PLA. Compared with the PBS and the PPC, the PBAT has better compatibility with the PLA. With the increasing of PBAT content, the impact strength of toughened PLA gradually increases, but the compatibility of PBAT and PLA bacomes worse.关键词
