Mixed matrix membranes(MMMs)demonstrate gas separation performance beyond conventional polymer membranes by combining the excellent selectivity of inorganic fillers with the excellent permeability of polymer matrices.The basic assumptions and limitations of the current popular effective medium(EMA)permeation models for predicting mixed matrix membranes were discussed.By comparing the predicted values of the permeability models with the experimental data,the application range of these models in predicting the permeability of MMMs was revealed.On this basis,the future development direction of the model was proposed,aiming at providing theoretical basis and guidance for the design and optimization of high-performance gas separation membrane materials.
