摘　　要：在全球环境污染愈发严重的背景下,塑料制品环境负面效应越来越显现,其不可降解的特性给环境带来了较大的承载负荷。聚乳酸的出现有效改变了这一现状,其良好的生物特性决定了其广泛的用途,并且由于其良好的生物相容性,所以改性与应用方面吸引了人们的研究目光。基于此,文章先对聚乳酸的生物性质进行了分析,从合成制备、改性研究等方面做了阐述,最后归纳了聚乳酸在各个领域的具体应用。Under the background ofincreasingly serious environmental pollution in China, plastic products are increasingly not recognized, and the non degradable characteristics have brought greater compliance to the environment. The emergence of polylactic acid has effectively changed this situation. Its good biological characteristics determine its wide range of uses, and because ofits good biocompatibility, its modification and application have attracted people’s research attention. Based on this, this paper first analyzes the biological properties of polylactic acid, and expounds the synthesis, preparation, modification and other aspects. Finally, it summarizes the specific applications of polylactic acid in various fields.
