Polyphosphoric acid solubility
WebApr 13, 2024 · The appeal of combining polybenzimidazole (PBI) and graphene oxide (GO) for the manufacturing of membranes is increasingly growing, due to their versatility. Nevertheless, GO has always been used only as a filler in the PBI matrix. In such context, this work proposes the design of a simple, safe, and reproducible procedure to prepare self … WebTheir syntheses, characterization, and properties such as density, viscosity, solubility, crystallinity, and thermal stability were described. Two model benzimidazoles (MBI) were also synthesized from o -phenylene diamine (OPDA) and the above two diacetic acids to confirm the formation of polymers from the tetraamines.
