Crosslinking density of crosslinkng agent affects performance of anion-exchange membrane. The 4-vinylbaenzyl chloride-co-styrene-co-2-hydroxyethyl acrylate copolymer (VSH) was synthesized by solution polymerization. The aminated VSH (AVSH) was synthesized by quaternarization reaction of VSH copolymer. The crosslinked AVSH membranes were prepared by glutaric acid and glutaric dialdehyde onto AVSH. The membranes properties, water uptake, ion-exchange capacity, electrical resistance, and charge-discharge performance, were measured by instrumental analysis. And then, the structure of membranes was investigated by FT-IR, GPC and NMR spectroscopy. |
