Desalination properties of side chain crosslinked sulfonated poly(arylene ether) composite membrane |
| 초록 |
Side chain crosslinked (C-SFPEx-CMy) sulfonated poly(arylene ether) (SPAE) membranes with varying degree of sulfonation (DS) were prepared and evaluated for use as a potential desalination film compostie membrane. C-SFPEx-CMy membranes were obtained by covalent crosslinking among ethynyl groups at the polymer side chain through thermal curing. The crosslinked network structure suppressed the water uptake and swelling ratio. C-SFPEx-CMy show the increase in NaCl rejection as DS decreases from 30% to 70%. And NaCl rejection of the membranes increased with increasing corsslinking moiety (CM) while water permeability decreases due to the net work structure. Particularly, crosslinked membrane of 30 % of CM molar ratio could enhance the salt (NaCl) rejection property up to 85.3 % comparing to 69.5% of crosslinked membrane of 10 % of CM molar ratio for the DS of 30 % but showed the decrease in water permeability from 0.10 L/m2hbar (C-SFPE30-CM10) to 0.03 L/m2hbar (C-SFPE30-CM30). |
