生物可降解薄膜的研究进展

Research progress of biodegradable film

塑料的大量使用和废弃给全球环境和资源带来了很多问题,包装薄膜是塑料废物的主要来源之一。生物可降解薄膜具有绿色环保、来源广的优点,是目前解决全球环境、资源问题最有潜力的研究方向之一,但也存在性能较差、降解不可控和成本较高的问题。综述了天然高分子合成的生物可降解膜薄(淀粉、蛋白质、果泥等)和人工合成的生物可降解薄膜(聚乳酸、聚己二酸对苯二甲酸丁二酯等)的研究进展,并对生物可降解薄膜材料的发展趋势进行了展望。

The massive use and disposal of plastics have brought many problems to the global environment and resources,and packaging films are one of the main sources of plastic waste.Biodegradable film is environmentally friendly with a wide range of sources,thus is one of the most promising research directions in terms of solving the current global environmental and resource crisis.Despite the advantages,it has the problems of poor performance,uncontrollable degradation and high cost.This article reviews the research progress of a variety of biodegradable films,including natural polymers such as starch and protein synthetic polymers such as polylactic acid and poly(butyleneadipate-co-terephthalate),as well as prospects for the development of biodegradable film materials.
