A hydrophilic polymer film consisting of a single phase blend comprising a polysulfone-based polymer and the hydrophilic copolymer

摘要

Polysulfone-based polymers, and poly - made up of a single phase blend comprising (vinylpyrrolidone styrene) copolymer, and initiates the flow of a polymer film having a network structure. ; The polymer film according to the present invention, could significantly reduce the transmission rate may be a conventional polyester is significantly improved without deterioration of the solute removal rate compared to the sulfone membranes, membrane contamination that occurs when a long-term use as separation membranes for water treatment. Thus, using a polymer film using the present invention as a separation membrane for treatment of an aqueous solution can dramatically improve the efficiency of the process, such as ultrafiltration, microfiltration process.
