摘　　要：聚乳酸(PLA)具有良好的生物相容性和生物可降解性,是最有前途的可生物降解高分子材料之一。本文以层状粘土和聚乳酸为原料,利用物理共混方法,制备了聚乳酸/蒙脱土复合材料,并对其物理性质,如拉伸、冲击、热稳定性等分析,并研究了X-射线衍射(XRD)。PLA is a biocompatible and biodegradable polymer.PLA has been defined as one of the most promising polymeric biodegradable materials.In the paper,the layered silicate clay and PLA were used as materials.PLA/MMT composites were prepared with by physical blending.The tensile strength,TGA and XRD of the composites were studied.
