硅橡胶渗透蒸发分离膜改性研究进展

Progress in Modification Technology of Silicone Rubber(PDMS) Membranes for Pervaporation

膜材料改性和膜结构改性作为改变硅橡胶渗透蒸发膜的分离性能(渗透通量和分离因子)、抗污染性、物理化学稳定性的有效手段而吸引了大量的研究和开发兴趣。重点介绍了硅橡胶渗透膜的改性方法研究进展,包括交联法、填充法、溶剂占位法等,并对其发展前景进行了展望。

The modification as an effective approach to improve the separation performance（permeation flux and selectivity）,the antifouling performance,the physical and chemical stability of pervaporation membranes,have attracted more and more research and development interests.The membrane modification methods including filling method,blending method and solvent occupation method,were discussed,and its development prospects was proposed.
