초록
In this study, several anion exchange membranes were successfully prepared by radiationgrafting of vinylbenzyl chloride (VBC) monomer onto a polyethylene-co-tetrafluoroethylene (ETFE)film and subsequent quaternarization with diamins such as 1,4-diazbicyclo[2,2,2]octane, N,N,N′,N′-tetramethyl-1,3-diaminopropane, N,N,N′,N′-tetramethyl-1,6-diaminohexane, and trimethylamine. The anion exchange capacities of the prepared membranes were determined by using acid-basetitration method. The cross-sectional morphology of the membranes was studied by using SEMinstrument. The cross-sectional distribution patterns of the grafted polymers with anion exchangefunctional groups were also studied by EDX analysis.
