Porous membrane having hydrophilic surface and preparation thereof |
| abstract |
PURPOSE: To obtain a porous membrane having a hydrophilic surface by irradiating a porous membrane made of polysulfone in a polymerizable monomer solution at room temp. under atmospheric pressure. n CONSTITUTION: A porous membrane made of polysulfone is washed with pure water and subsequently immersed in a solution containing about 0.1-50wt.% of a polymerizable monomer such as acrylamide and irradiated with ultraviolet rays having proper intensity at room temp. under atmospheric pressure under a proper irradiation distance/proper irradiation time condition to perform graft polymerization. The obtained polymer porous membrane having a hydrophilic surface is washed with pure water. By this method, a membrane wherein the rapid lowering of a filtering speed due to the adsorption of protein is solved while the chemical resistance and physical strength of the porous membrane composed of a hydrophobic substrate are held and a high filtering speed is imparted is obtained. Therefore, a filtering time can be shortened to a large extent. n COPYRIGHT: (C)1990,JPO&Japio |
