| Abstract: | The use of supercritical CO2 as non-solvent has been attracting attentions in the formation of polymer microporous membrane. Advantages of this method are high mass transport coefficient, rapid drying of the polymer membrane without collapse of the structure, easy recovery of solvent and recycling of CO2 and low toxicity of CO2 . The thermodynamics and kinetics theory in the preparation process were presented. The studies on polystyrene, polyacrylonitrile, polyethersulfone microporous membrane etc were mainly introduced. |
