New polybenzimidazoles for producing medium-temperature proton-exchange membranes

Autor: A. L. Rusanov, A. Yu. Leikin

Publikováno v: Polymer Science Series C. 51:8-11

H3PO4-doped proton-exchange membranes based on benzimidazole-2-yl-substituted polybenzimidazoles have been obtained and studied. Attempts have been made to stabilize the mechanical properties of doped membranes by crosslinking of the initial polymers
