제목 Synthesis and Properties of Poly(p-phenylene)-based Ionomers with Controlled Molecular Weight and Highly Sulfonated Multi-phenyl Pendants for VRFB
초록 Vanadium redox flow battery(VRFB) is a promising technology for energy storage system. In VRFB, The ideal  polymer electrolyte membranes for VRFB is expected to possess high proton conductivity, low vanadium ion permeability and good chemcial stability. We synthesized Poly(p-phenylene)-based membrane materials by Ni(ǁ)-catalyzed coupling polymerization. We have investigated their physical properties and morphology. This membrane showed well-developed phase separation between the hydrophilic and hydrophobic domains and also showed highly connected hydrophilic channels, which gave enhanced proton conduction and good dimensional stability. Also These membranes show low vanadium ions permeability and superior chemical stability. Furthermore, These membranes exhibit relatively high efficiencies and a stable performance in 100 cycle test, which demonstrates its excellent chemical stability under the strong acidic and oxidizing conditions.
