摘要

介绍了近年来对PDMS分离层的改性方法，包括填充、共混、交联、共聚和表面改性，旨在研究新型PDMS疏水性膜材料，实现有机物的高效分离，同时提出目前PDMS分离膜在应用中存在的问题和未来的发展方向。

Abstract

The modification methods for polydimethylsiloxane (PDMS) in recent years,including filling,blending,crosslinking,copolymerization and surface modification,are reviewed,aiming to develop novel PDMS-based hydrophobic membrane material to achieve the efficient separation of organic compounds.The existing problems in the application of PDMS separation membrane and the development direction in the future are also put forward.
