POLY-VALENT ION COMPLEX COMPOSITE MEMBRANE FOR SEPARATING ORGANIC MIXTURE AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A poly-valent ion complex composite membrane for separating organic mixture is provided to produce poly-valent ion complex composites which do not show the trade-off phenomena that is a common phenomena of existing products and is useful as separation membrane due to excellent penetrating selectivity. The membrane has a strong mechanical strength and good moldability, the manufacturing process being very easy. CONSTITUTION: The poly-valent complex composite membrane for separating organic mixture is characterized in that a complex membrane of cationic polymer of poly-saccharide and anionic polymer of poly-saccharide formed on the surface of a fine porous supporter, the supporter being a polymer material selected from polysulfone, polyester sulfon, polyimide, polyether imide, polyamide imide and polyacrylonitrile, an inorganic material selected from alumina and silica, and a metal material selected from Ni and steel, the thickness of complex membrane being 0.01-1m.
