摘要：NOVELTY - The method involves taking polysulfone polymer resin dissolved in strong polar solvent, and performing a phase separation process to prepare uniform transparent solution. A primary film is immersed in water. A solidifying, cleaning and drying process is carried out to obtain a finished product. USE - Reverse thermally induced phase separation method for preparing a polysulfone polymer micro-porous film. ADVANTAGE - The polysulfone polymer micro-porous film prepared by the method has environment-friendliness, low energy consumption and simple film forming process. DESCRIPTION OF DRAWING(S) - The drawing shows a photographical representation of a reverse thermally induced phase separation method for preparing a polysulfone polymer micro-porous film.
