Dissolution and regeneration of polybenzimidazoles using ionic liquids

We report here the initial results that polybenzimidazole can be dissolved in and regenerated from, 1-butyl-3-methylimidazolium chloride and other hydrophilic ionic liquids, which may enable the application of ionic liquids as alternatives to environmentally undesirable solvents currently used for dissolution of this polymer.

PBI can be dissolved in [BMIM]Cl at 140 °C, which may enable the application of ionic liquids as alternatives to environmentally undesirable solvents currently used for dissolution of this polymer.Figure optionsDownload as PowerPoint slide
