Morphological rearrangement of ionic channels in solid state disulfonated poly(arylene ether) copolymers via direct fluorination |
초록 |
Disulfonated poly(arylene ether sulfone) random and multiblock copolymers with the same chemical architecture state were physicochemically tuned in solid membrane via direct fluorination under a dilute fluorine (F2)-nitrogen (N2) mixture, which was expected to minimize chemical degradation by a highly reactive F2 gas. The direct fluorination and subsequent acidification enabled C-H bonds of aromatic rings in hydrophobic domains or blocks of the copolymers to be selectively converted into C-F bonds. Interestingly, the direct fluorination on the copolymer membranes influenced their morphologies and water/ion transport properties in different ways, even though both sulfonic acid level and swelling ratio of the precursor copolymers were similar. |
