Abstract : Advances in batteries, fuel cells, and perm selective membranes are materials limited. New acid- and ion-containing polymers must be designed and synthesized to deliver improved combinations of mechanical toughness, transport selectivity and ionic conductivity. A formidable obstacle toward producing the next generation of polymer membranes is the fundamental understanding of how chemical structure and polymer processing impact the morphology that subsequently dictates ionic conductivity.
