This article defined and provided an overview of the essential affecting factors for the structure and performances of polymeric membranes with asymmectric structure prepared by L-S phase inversion process. The effect of vital thermodynamic factors,  including the molecular weight and concentration of polymer, the solvent and its solvation, the additive selection, and the temperature of casting solution on the structure of casting solution; as well as the impact of critical kinetic factors, such as the solvent evaporation rate and gelation rate on the desolvation rate of the nascent membrane, were systemetically discussed. The methods to charicterize the relavent thermodynamic and kinetic affecting factors were also reviewed.
