Reverse electrodialysis (RED) is a promising technology for green energy. Important requisites for ion exchange membrane in this application are low price and high power density. In this work, 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 composite. The selected composite membranes were crosslinked to improve their stability related to swelling ratio in salinity water. Membrane properties, such as chemical composition (NMR), water uptake, ion exchange capacity, 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 equivalent condition. |
