聚乳酸的合成及应用研究

Study on Synthesis and Application of Polylactic Acid

聚乳酸也称聚丙交酯,是以乳酸为主要原料聚合得到的聚合物。聚乳酸原料来源充分,生产过程无污染,产品可生物降解,因此是理想的绿色高分子材料。在环境污染问题日益严峻的背景之下,为更好地解决环境问题,且满足人类发展所需,越来越多的科研人员将目光投到生物可降解高分子材料领域。经过科研人员夜以继日的努力,聚乳酸这一种生物可降解高分子材料应运而生。本文立足于聚乳酸这一新型材料,对它的合成和应用前景进行了探讨分析。

Polylactic acid,also known as poly(lactide),is a polymer derived from lactic acid polymerization as the main raw material.The source of polylactic acid raw material is sufficient,the production process is pollution-free,and the product is biodegradable,so it is an ideal green polymer material.In the background of increasingly severe environmental pollution,in order to better solve environmental problems and meet the needs of human development,more and more researchers focus on the field of biodegradable polymer materials.Through the efforts of researchers day and night,polylactic acid,a biodegradable polymer material,came into being.Based on the new material polylactic acid,the synthesis and application prospect of polylactic acid are discussed in this paper.
