HOLLOW FIBER MEMBRANE, AND METHOD FOR PRODUCING HOLLOW FIBER MEMBRANE |
摘要 |
One aspect of the present invention concerns a porous hollow fiber membrane containing a vinylidene fluoride-based resin. The hollow fiber membrane has a gradient structure in which a pore diameter of pores in the hollow fiber membrane gradually becomes smaller at least toward one of inner and outer peripheral surface sides and is hydrophilized by containing a crosslinked body of a polyvinylpyrrolidone-based resin. |
