Desalination properties of sulfonated poly(arylene ether) composite membrane prepared by electrospinning |
| 초록 |
A novel composite membrane for potential desalination was prepared by coating of sulfonated poly(arylene ether) on non-woven web. The non-woven web was made of end-group crosslinkable flurorinated poly(arylene ether) with electrospinning. The crosslinked non-woven web was obtained by covalent crosslinking among ethynyl groups at the polymer chain end via thermal curing. With varying degree of sulfonation (DS) sulfonated poly(arylene ether) of top layer controlled salt rejection and permeability. The compostie membranes show the increase in NaCl rejection as DS decreases from 20% to 60%, while water permeability decreases due to the increase of hydrophilicity. The order of salt rejection was as follow: Na2SO4 (88.4%), NaCl (79.3%), MgSO4 (70.2%), Mg2Cl2 (62.3%). |
