生物可降解膜的改性制备及其应用进展

Recent progress on preparation,modification and application of biodegradable membrane

高分子废弃物对人类的生存环境已产生了巨大的危害,因此发展可降解的高分子材料迫在眉睫。生物可降解高分子材料是一种对环境友好的材料,可以完全被降解且在降解过程中产生的物质对环境无害。对常用的石油基、生物基和天然高分子基的生物可降解高分子材料及其膜的改性制备,以及在不同领域的应用等方面进行了综述。

Polymer waste has caused great harm to the living environment of human beings,so the development of degradable polymer materials is extremely urgent.Biodegradable polymer materials are environmentally friendly materials that can be completely degraded and the substances produced during the degradation process are not harmful to the environment.The preparation of commonly used petroleum-based,bio-based and natural polymer-based biodegradable polymer materials and their membrane modification,as well as their applications in different fields were reviewed.
