An anion-conductive microporous membrane composed of a rigid ladder polymer with a spirobiindane backbone

摘要

A free-standing membrane that consists of a newly synthesized spirobiindane-based microporous polymer carrying trimethylammonium hydroxide groups exhibited a good OH- conductivity of 65 mS cm(-1) at 80 degrees C under 100% relative humidity, which demonstrates its potential for use in solid-state alkaline fuel cells.
