Poly(ionic liquid)s (PILs) have emerged as powerful materials in gas separation, ion conduction electrolytes and adhesive and anti-fouling coating. The incorporation of ionic groups into the polymer introduces electrostatic interactions that result in intriguing mesoscale structures and macroscopic responses. Using controlled polymerization methods, we highlight (1) low Tg, imidazolium-containing AB diblock copolymers with deuterium labelling to study in situ meso-scale morphological changes during an actuation process, (2) doubly charged ABA triblock copolymers to investigate ion aggregation within microphase-separated morphologies and their influence on macroscopic thermomechanical properties, and (3) the application of phosphonium-containing crosslinked materials in additive manufacturing to achieve conductive 3D objects with access to high resolution structural hierarchy controls. Rational design of ionic liquids in polymers introduces unprecedented microscopic phenomena and macroscopic properties, representing new directions in ion-containing polymers.
