FOULING RESISTANT POLYSULFONE MEMBRANE USING SULFONATED POLYSULFONE POLYMER, ITS PREPARATION METHOD AND MANUFCTURING METHOD OF SULFONATED POLYSULFONE POLYMER

摘要

PURPOSE: An antifouling polysulfone membrane using a sulfonated polysulfone polymer, a preparation method thereof and a method for manufacturing the sulfonated polysulfone polymer are provided to maintain permeability and a hydrophilic property, to improve an antifouling property, and to ensure excellent mechanical, chemical and thermal stability. CONSTITUTION: An antifouling polysulfone membrane comprises a membrane formed of a polysulfone polymer and 1~20 weight% of a sulfonated polysulfone polymer represented by chemical formula 1 included in the membrane. In chemical formula 1, m/(n+m) is 0.6 - 0.9 and x is 50 - 1000. The polysulfone polymer is a single or mixed form s selected from the group consisting of polysulfone, polyethersulfone and polyarylethersulfone polymer.
