Gas membrane separation technology is widely applied in different industry processes because of its advantages on separation performance and economic efficiency. It is usually difficult and time-consuming to determine the suitable membrane materials for specific industrial separation processes through traditional experimental research methods. Molecular simulation is widely used to investigate the microscopic morphology and macroscopic properties of materials, which is helpful to guide the improvement of membrane materials. This paper comprehensively reviews the molecular-level exploration on the dominant mechanism and influencing factors of the gas membrane-based separation. Thermodynamics and kinetics of polymer membrane synthesis, molecular interactions among the penetrated gases, relations between the membrane properties and transport characteristics of different gases in the composite membrane are summarized and discussed. The limitations and perspectives of molecular simulation method in the study of gas membrane separation process are also concluded to rationalize the potential and innovative. This review is expected to provide a more comprehensive reference for promoting the materials design and engineering application of gas separation membrane.
