Abstract
Membrane separation technology has become popular in recent years as an energy–saving technology in various industrial fields. However, there are almost no membranes that can be used in organic solvents. In this study, we succeeded to fabricate organic solvent resistant microfiltration (MF) and ultrafiltration (UF) membranes by the combined use of thermally induced phase separation (TIPS) method and non–solvent induced phase separation (NIPS) method. Membrane modules made by the prepared membranes were also resistant to many organic solvents, and they could be used in long–term membrane separation test for organic solvent systems such as polystyrene / toluene and Vitamin B12 / methanol.
