生物可降解聚乳酸(PLA)的合成方法及应用

Synthesis and applications of biodegradable polylactic acid (PLA)

聚乳酸(PLA)作为生物基聚合物,可有效代替石油基产品。同时,完全符合我国“碳减排”大政策,可有效缓解白色污染及环境污染。目前为止,聚乳酸在生物医学、快递包装、组织工程、抗癌领域、纳米生物复合材等领域中表现出优异且独特的性能。然而,聚乳酸机械和物理性能不如石油基材料且生产成本是传统塑料的3~5倍。因此,研发出经济使用的聚乳酸成了重中之重。简要的讲述了PLA在包装行业、组织工程领域及生物医学方面的应用。

Polylactic acid(PLA),as a bio-based polymer,can effectively replace petroleum based products.At the same time,it fully conforms to China's"carbon emission reduction"policy,which can effectively alleviate white pollution and environmental pollution.So far,polylactic acid(PLA)has shown excellent and unique properties in fields such as biomedicine,express packaging,tissue engineering,anticancer fields,and nano biological composites.However,the mechanical and physical properties of polylactic acid are not as good as petroleum based materials and the production cost is 3-5 times higher than traditional plastics.Therefore,the development of economical polylactic acid has become a top priority.The applications of PLA in the packaging industry,tissue engineering,and biomedical fields are briefly described.
