PBI Membranes Via the PPA Process,the PBI solution directly from PPA not only improves manufacturability, but allows for various chemistries of PBI to be synthesized by overcoming some of the solubility limits seen in the traditional synthesis and imbibing process. PBIs prepared via the sol–gel PPA process exhibit high inherent visc

Polybenzimidazoles with Enhanced Basicity: A Chemical Approach for Durable Membranes,oaches to improve the conductivity and its stability are presented by tailoring the polymer basicity: (a) modification of the polymer backbone by synthesis of new monomers and (b) fabrication of (nano)composite membranes with functionalized fillers. Chemical modification of the polymer backbone is l
