摘　　要：以反渗透复合膜和气体分离用复合膜为例，介绍了复合膜中存在的界面现象，提出了界面控制影响复合膜性能的五个可能因素：界面粗糙度及其分布、界面极性与非极性、界面官能团与化学元素组成、界面荷电性和界面结合能，并对界面控制影响复合膜性能的机理和规律作出了一定的理论分析和预测。This review systematically introduces the interfacial phenomena of the composite membrane emphasizing the focus on the reverse osmosis composite membrane and the composite membrane for gas separation.And on the basis of the above ,five factors that take effect on the performance of composite membrane are suggested: the degree and its distribution of the crudity of the interface ,polar and nonpolar character of the interface,the chemical component and the structure of the functional group of the interface,the electrical character and the combined energy of the composition surface . Furthermore,theoretical analysis is given about the relationship between the interfacial controls and the performance of the composite membrane.
