High performance polymeric blend membrane materials based on N-heterocycles and acid-base interactions

摘要

The present invention includes method, compositions and devices including acid-base polymer membranes with high proton conductivity at low relative humidity, good thermal and mechanical stabilities and low methanol crossover. The acid-base polymer membrane includes an acidic polymer mixed with a basic polymer. The acidic polymer includes an acidic group attached to an aromatic polymer, while the basic polymer includes at least one heterocyclic ring structure attached to an aromatic polymer.
