제목 Polyethylene reinforced anion exchange membrane based on cross-linked polystyrene-co-poly(phenylene oxide) for reverse electrodialysis
초록 In recently, reverse electrodialysis(RED) is thought to be a clean energy source that can fulfill the current global electricity demand. Important requisites for ion exchange membrane in RED systems are high power density. In this study, novel anion exchange membranes(AEMs) are composed with different mixtures of functionalized poly(2,6-dimethyl-1,4-phenylene oxide)(PPO) and polystyrene
(PS) in polyethylene matrix. The composite membranes were cross-linked to improve their mechanical stability. Membrane properties, such as chemical structure(1H-NMR), ion exchange capacity, water uptake, pH tolerance, permselectivity, area resistance were measured. Membranes were also evaluated measuring the power density with RED stack system. In conclusion, APSPPO-5.0 that we proposed showed 2.3% power density relatively greater than commercial AMX membrane under the same condition.
