Anion-conducting Pore-filling Membranes with Optimization of Transport Number and Resistance for Reverse Electrodialysis

Abstract

Abstract Pore-filling membranes filled with quaternized poly(styrene-co-ethylene glycol dimethacrylate) were prepared with the degree of crosslinking (DC) for reverse electrodialysis (RED). It was shown in power density performance that the pore-filling membranes with low DC had lower open circuit voltage (Voc) and resistance, but those with high DC had higher Voc and resistance than the commercial AMX membrane. Thus, the compromise between their transport number and resistance is necessary for the application of pore-filling membranes in RED.
