Since Loeb and Sourirajan has introduced phase inversion method for membrane fabrication, the phase separation technique became the mainstream of membrane fabrication methods. Phase inversion includes solvent evaporation, vapor induced phase separation, thermally induced phase separation (TIPS) and nonsolvent induced phase separation (NIPS). Among those, NIPS and TIPS process is widely studied and employed for membrane fabrication. Depending on the membrane fabrication processes such as NIPS and TIPS, corresponding morphology differs from macrovoid structure to spherulitic structure, respectively. In this presentation, comparison of NIPS and TIPS effect on the final membrane morphology and controlling the membrane morphology by tuning the NIPS and TIPS effect will be presented.
