高分子塑料生物可降解性的研究进展

Research Progress on the Biodegradability of Polymer Plastics

随着消费者环保意识的提高,可生物降解高分子塑料受到广泛关注。详细介绍了高分子塑料的生物降解机理,重点介绍了有氧生物降解和厌氧生物降解两种不同环境中的生物降解,并针对有氧生物降解过程中降解产物及降解残留材料进行了分析。另外,针对聚乙烯醇的降解机理及影响降解的因素作了详细介绍。

Biodegradable polymer plastics have received widespread attention with the increasing awareness of environmental protection among consumers.This article provides a detailed introduction to the biodegradation mechanism of polymer plastics.Emphasis was placed on the biodegradation in two different environments:aerobic biodegradation and anaerobic biodegradation.And an analysis was conducted on the degradation products and residual materials during the aerobic biodegradation process.In addition,a detailed introduction will be provided on the degradation mechanism and influencing factors of polyvinyl alcohol.
