摘　　要：树枝型聚合物是具有内部疏松、外部致密、端基官能团众多等结构的高度支化聚合物,这些特点使得树枝型聚合物具有多种不同于线性聚合物的特性,与膜和膜技术相结合有特殊意义.介绍了树枝型聚合物气体分离膜、支撑液膜、离子交换膜、膜表面改性以及树枝型聚合物参与的膜过程等方面的研究进展,简要展望了基于树枝型聚合物的分离膜与膜技术的发展趋势.Different to their linear analogues, dendritic polymers have a large number of terminal functional groups, highly branched structure, interior voids and dense outer layers etc. Such special structures aroused the interests in their applications in membrane materials and technologies. In this paper, the recent advances in gas separation membranes, supported liquid membranes, ion- exchange membranes, surface modification of membranes and relevant membrane processes basing on dendritic polymers are reviewed. And the future development trends in this field are also briefly proposed.
