Pore size control of electrospun nanofiber support layer for improved power density of pressure-retarded osmosis |
| 초록 |
One of the bottle-necks of a salinity gradient power system is the limitation of membrane performance to extract high energy efficiency. This study demonstrates the membrane structure design to improve power density of pressure retarded osmosis (PRO) systems. To achieve an upgraded membrane for PRO, electrospinning technology was used to prepare the high porous support layer. A facile method was developed to fabricate interconnected electrospun nanomats. The opening pore size of nanomat was controlled by the electrical surface charge to promote the stability of active layers. The power density was 10 W/m2 which is quite so high for commercialization when the fully aromatic polyamide was introduced as the active layer. |
