Nanoporous Membranes Using Asymmetric Block Copolymers for Bio-materials Separation |
| 초록 |
Nano-separated block copolymers have recently gained significant attention as future nano-materials for their potential uses. Especially, uniformity of self-assembled cylindrical domains can make block copolymer to apply for biomaterial separation requiring high selectivity. In this study, we introduce a new double layered nanoporous membrane suitable for biomaterial filtration. One layer is a block copolymer thin film having cylindrical pores induced by UV irradiation and swelling of PMMA block with narrow pore size distribution. The support layer is a conventional micro-filtration membrane with a broad pore size distribution. This asymmetric membrane showed very high selectivity and flux for the separation of human rhinovirus type 14 which has a diameter of ~ 30 nm and is a major pathogen of the common cold in humans. |
