Synthesis Of A Polybenzimidazole Membranevia Sol-Gel Method

In this study para-polybenzimidazole (p-PBI) was synthesized by solution polymerization method. The synthesized polymer was used to prepare a polymer electrolyte membrane (PEM) via sol-gel method and for characterization. The chemical structure of the synthesized polybenzimidazole was confirmed by 1H NMR and FTIR analysis methods. 1H NMR and FTIR spectrum of the synthesized polymer is consistent with literature. Thermogravimetric analysis showed that the degradation temperature of themembrane is 650oC. Index Terms—p-PBI, Polybenzimidazole, Polymer electrolyte membrane, Sol-gel.
