The oceans have been investigated to obtain various forms of renewable energy for decades. One of the ocean energy sources is salinity gradient energy, which is available from the change in Gibbs energy during mixing of seawater and river water. The main components of a reverse electrodialysis system are ion exchange membranes such as CEM, AEM. CEM requires low electric resistance , high permselectivity. Semi-interpenetrating network have high mechanical property and good chemical stability. In this study, cation exchange membranes based on semi-IPNs were prepared for RED application. Membrane properties, such as ion exchange capacity, water uptake, morphology, permselectivity, area resistance were measured. In conclusion, lab-made membrane showed excellent power density relatively greater than commercial CMV membrane under the same condition. |
