| 摘要 |
The present invention relates to a double layer hollow fiber membrane including: a porous inner support layer having microscopic voids; and a nanoparticle-containing porous outer selective layer having macroscopic voids, and to a manufacturing method thereof. According to the present invention, a nanoparticle-containing double layer hollow fiber membrane can be manufactured, ranging from: a microfilter membrane (MF) whose water flux and virus removing rates are excellent, without generating exfoliation on the support layer and selective layer through a triple spinning nozzle; ultrafiltration membrane (UF); or nanofiltration membrane (NF), while capable of being applied to a water purifying device. The objective of the present invention is to provide: the nanoparticle containing double layer hollow fiber membrane whose water flux and virus removing rates are excellent without generating exfoliation on the support layer and selective layer; and the manufacturing method thereof. |
