Abstract
Triblock copolymers useful for forming ion conductive membranes are provided. The triblock copolymers are characterized by having either a hydrophobic-hydrophilic-hydrophobic or a hydrophilic-hydrophobic-hydrophilic polymer sequence that induces a microphase separated morphology. Variations in which the hydrophilic polymer sequence component includes either acid groups or salts of acid groups are also disclosed. Methods for forming an ion conductive membrane from the triblock copolymers are provided.
