Abstract: This paper reviews the development of inorganic and organic oxygen-nitrogen separation membranes. The progress of organic-inorganic mixed membranes is introduced. The problems and solutions of the mixed membranes are presented. The Maxwell model and the modified Maxwell model for predicting permeation properties of the mixed membranes are given. Finally，the development trend of mixed membranes is proposed.
