MEMBRANE FOR WATER PURIFICATION USING MECHANICALLY AND STRUCTURALLY ROBUST SULFONATED BLOCK COPOLYMERS

摘要

PURPOSE: A separation film for water purification using sulfonated polymer film and a manufacturing method thereof are provided to have strong physical strength, rapid separation as a formation of water channel, and separation of neutral molecule according to size. CONSTITUTION: A separation film for water purification comprises a cross-linked sulfonated block copolymer. The cross-linked sulfonated block copolymer comprises at least one of cross-linked block and at least one of sulfonated block. The sulfonated block is a sulfonated polystyrene block.
