A novel polysulfone-based ternary nanocomposite membrane consisting of metal-organic framework and silica nanoparticles: As proton exchange membrane for polymer electrolyte fuel cells

What is it about?

In this study, the preparation and characterization of a new ternary nanocomposite polymer electrolyte membrane containing sulfonated PSU, MOF and silica nanoparticles were investigated as a polymer electrolyte membrane. The encapsulation of imidazole in NH2MIL-53(Al) and sulfonic acid functionalization of silica have been developed to produce proton-conducting nanoparticles. In addition, photografting polymerization of AMPS from PSU and sulfonation of PSU backbone was designed to prepare PSU chains bearing sulfonic acid groups.
