WebCrosslinking. Before crosslinking, the membranes were stabilized according to the literature. 33 In brief, the membranes were first stabilized by soaking them for 20 minutes in 0.5% sodium hydroxide (NaOH) dissolved in 100% ethanol, followed by five times washing in PBS for 30 seconds. The stabilized membranes were then crosslinked in 5% (w/v) … Web13 de abr. de 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 …
