摘　　要：聚L-乳酸(PLLA)是一种来源于玉米的纯天然高分子材料,无毒副作用、可降解、生物相容性及细胞亲和性好,广泛应用于生物医用材料。本文以聚L-乳酸用作骨折内固定支架为例,简要介绍了PLLA及其复合材料的制备和性能表征,并提出了当前存在的问题。Poly L-lactic acid （PLLA）, widely used in biomedicine, is natural polymer material made from corn, which is nontoxic, biodegradable and biocompatible with organism like cell. In this paper, the preparation and the characterization of PLLA and its composites are introduced briefly, while PLLA is used for internal fracture fixation material as an example, after which some problems are put forward.
