Polymerized ionic liquid (PIL) block polymers are an emerging class of polymers that synergistically combine the benefits of both ionic liquids (ILs) and block polymers into one material, where the former possesses a unique set of physiochemical properties and the latter self assembles into a range of nanostructures. The potential to synthesize a vast array of new block polymers is almost limitless with numerous IL cations and anions available. In this work, the ion transport properties and morphology of a variety of PIL homopolymers, diblock copolymers, and multiblock polymers synthesized in our laboratory will be presented. Specifically, a fundamental understanding of transport-morphology relationships in these materials as a function of various chemistries and chain architectures will be examined. The application of these materials as solid-state separators for lithium-ion batteries, membranes for carbon dioxide separation, and as anion exchange membranes for alkaline fuel cells will also be discussed.
